title: RS-UVPA Power Amplifier
|
||||||
|
description: 5W power amplifier companion board for the RS-UV3A
|
||||||
|
---
|
||||||
|
|
||||||
|
The RS-UVPA is a 5W power amplifier designed to integrate with the RS-UV3A transceiver, boosting output power for improved range.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The RS-UVPA provides:
|
||||||
|
- **5W output** on 2m and 1.25m bands
|
||||||
|
- **4W output** on 70cm band
|
||||||
|
- **Low-noise preamplifier** for improved RX sensitivity
|
||||||
|
- **SWR protection** to prevent amplifier damage
|
||||||
|
- **Band-keying outputs** for external amplifiers
|
||||||
|
|
||||||
|
## Specifications
|
||||||
|
|
||||||
|
| Parameter | Specification |
|
||||||
|
|-----------|---------------|
|
||||||
|
| **TX Frequency Range** | 144–148 MHz, 220–225 MHz, 432–450 MHz |
|
||||||
|
| **RX Frequency Range** | 130–500 MHz |
|
||||||
|
| **Drive Level** | 200 mW – 1W |
|
||||||
|
| **Output Power** | 5W min (2m/1.25m), 4W min (70cm) |
|
||||||
|
| **Spurious** | > 53 dBc, typically 60 dBc |
|
||||||
|
| **Antenna Impedance** | 50Ω |
|
||||||
|
| **SWR Trip** | 3:1 |
|
||||||
|
| **RX Gain** | 2–3 dB or 12–15 dB (jumper selectable) |
|
||||||
|
| **RX Noise Figure** | 1.5 dB max |
|
||||||
|

|
||||||
|
| **TX Current** | 2A max |
|
||||||
|
| **RX Current** | < 50 mA |
|
||||||
|
| **Size** | 120 × 75 × 25 mm |
|
||||||
|
|
||||||
|
## Operation
|
||||||
|
|
||||||
|
Once installed, the RS-UVPA operates transparently—it automatically switches between TX and RX and selects the correct band filtering.
|
||||||
|
|
||||||
|
### SWR Protection
|
||||||
|
|
||||||
|
The RS-UVPA includes SWR protection:
|
||||||
|
- **SWR LED** illuminates when high SWR is detected
|
||||||
|
- Amplifier is disabled for remainder of transmission
|
||||||
|
- Normal operation resumes on next transmission
|
||||||
|
|
||||||
|
:::warning[Antenna Required]
|
||||||
|
Always connect an antenna or 50Ω load before transmitting. Operating without a load can damage the amplifier despite SWR protection.
|
||||||
|
:::
|
||||||
|
|
||||||
|
:::danger[Shielding Required]
|
||||||
|
Do NOT operate with the antenna directly connected to the PCB unless the RS-UVPA is mounted in a **shielded metal enclosure**. Otherwise, the PCB becomes part of the antenna system, causing unexpected behavior or component damage.
|
||||||

### Required Modifications
|
||||||
|
|
||||||
|
Before installing the RS-UVPA on the RS-UV3A:
|
||||||
|
|
||||||
|
#### Step 1: Prepare the RS-UV3A
|
||||||
|
|
||||||
|
1. **Remove solder from SJ1** — This solder jumper routes RF to the SMA jack. Use solder wick to clear it.
|
||||||
|
2. **Remove the VIN power connector** — It interferes with the amplifier's power connector. The RS-UVPA will supply power to the RS-UV3A.
|
||||||
|
|
||||||
|
:::tip
|
||||||
|
The SMA jack can remain installed—it doesn't interfere mechanically and is difficult to remove.
|
||||||
|
:::
|
||||||
|
|
||||||
|
#### Step 2: Add Headers to RS-UV3A
|
||||||
|
|
||||||
|
Solder three headers to the RS-UV3A:
|
||||||
|
|
||||||
|
| Header | Pins | Purpose |
|
||||||
|
|--------|------|---------|
|
||||||
|
| AMP | 6 | Amplifier interface |
|
||||||
|
| PW | 2 | Power switch |
|
||||||
|
| PA | 2 | RF connection |
|
||||||
|
|
||||||
|
**Soldering tips:**
|
||||||
|
- Solder one pin first
|
||||||
|
- Verify header is seated flat and perpendicular
|
||||||
|
- Solder remaining pins
|
||||||
|
|
||||||
|
#### Step 3: Mate the Boards
|
||||||
|
|
||||||
|
1. Align headers on RS-UV3A with sockets on RS-UVPA
|
||||||
|
2. Press boards together firmly
|
||||||
|
3. Install jumper across PW header (or connect switch)
|
||||||
|
|
||||||
|
The RS-UVPA has a redundant PW header for switch connection.
|
||||||
|
|
||||||
|
#### Step 4: Enclosure Mounting
|
||||||
|
|
||||||
|
The board stack can be mounted using:
|
||||||
|
- PCB mounting holes
|
||||||
|
- Extruded enclosures for 120×75 mm boards (e.g., Hammond 1455K1201)
|
||||||
|
- HobbyPCB enclosure (available on website)
|
||||||
|
|
||||||
|
**Important:** Transfer the plastic cap from the RS-UVPA's SMA connector to the unused RS-UV3A SMA connector to prevent confusion.
|
||||||
|
|
||||||
|
## Connections
|
||||||
|
|
||||||
|
### Power
|
||||||
|
|
||||||
|
| Parameter | Specification |
|
||||||
|
|-----------|---------------|
|
||||||
|
| Connector | On RS-UVPA (shared with RS-UV3A) |
|
||||||
|
| Voltage | 8V – 15V DC |
|
||||||
|
| Current | 2A max (TX) |
|
||||||
|
|
||||||
|
The RS-UVPA provides power to the RS-UV3A through the interconnecting headers.
|
||||||
|
|
||||||
|
### Antenna
|
||||||
|
|
||||||
|
Connect antenna to the RS-UVPA SMA jack (not the RS-UV3A jack when mated).
|
||||||
|
|
||||||
|
### Control Outputs
|
||||||
|
|
||||||
|
The RS-UVPA provides band-select outputs for keying external amplifiers:
|
||||||
|
|
||||||
|
| Signal | Description |
|
||||||
|
|--------|-------------|
|
||||||
|
| 2m Key | Active during 2m TX |
|
||||||
|
| 1.25m Key | Active during 1.25m TX |
|
||||||
|
| 70cm Key | Active during 70cm TX |
|
||||||
|
|
||||||
|
## RX Preamplifier
|
||||||
|
|
||||||
|
The RS-UVPA includes a switchable LNA (Low-Noise Amplifier):
|
||||||
|
|
||||||
|
| Mode | Gain | Use Case |
|
||||||
|
|------|------|----------|
|
||||||
|
| Low Gain | 2–3 dB | Overcomes amplifier insertion loss |
|
||||||
|
| High Gain | 12–15 dB | Improved weak-signal reception |
|
||||||
|
|
||||||
|
Select mode via jumper on the RS-UVPA board.
|
||||||
|
|
||||||
|
### When to Use High Gain
|
||||||
|
|
||||||
|
- Weak signal work (DX, satellites)
|
||||||
|
- When the RS-UV3A's sensitivity is limiting
|
||||||
|
- Base station installations with long feedlines
|
||||||
|
|
||||||
|
### When to Use Low Gain
|
||||||
|
|
||||||
|
- Strong signal environments
|
||||||
|
- To avoid receiver overload
|
||||||
|
- Mobile installations in urban areas
|
||||||
|
|
||||||
|
## Drive Level Adjustment
|
||||||
|
|
||||||
|
The RS-UVPA is optimized for the RS-UV3A's ~200 mW output. If using with other transmitters:
|
||||||
|
|
||||||
|
| Drive Power | Notes |
|
||||||
|
|-------------|-------|
|
||||||
|
| < 200 mW | Reduced output power |
|
||||||
|
| 200 mW – 500 mW | Optimal range |
|
||||||
|
| 500 mW – 1W | May require attenuator adjustment |
|
||||||
|
| > 1W | Not recommended |
|
||||||
|
|
||||||
|
For drive levels above 500 mW, internal attenuator adjustment may be required—contact HobbyPCB for guidance.
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Low Output Power
|
||||||
|
|
||||||
|
1. Check drive level from RS-UV3A (`PW1` = high power)
|
||||||
|
2. Verify antenna connection
|
||||||
|
3. Check for SWR LED illumination
|
||||||
|
4. Measure DC input voltage (should be 8V–15V)
|
||||||
|
|
||||||
|
### SWR LED Always On
|
||||||
|
|
||||||
|
1. Check antenna connection
|
||||||
|
2. Verify antenna is for correct band
|
||||||
|
3. Measure antenna SWR with analyzer
|
||||||
|
4. Check for damaged feedline
|
||||||
|
|
||||||
|
### No TX
|
||||||
|
|
||||||
|
1. Verify RS-UV3A is transmitting (TX LED)
|
||||||
|
2. Check header connections between boards
|
||||||
|
3. Verify power is applied to RS-UVPA
|
||||||
|
|
||||||
|
### Receiver Desensitized
|
||||||
|
|
||||||
|
1. Check antenna connection
|
||||||
|
2. Try low-gain preamp mode
|
||||||
|
3. Verify no strong nearby transmitters
|
||||||
|
|
||||||
|
## Using with Other Radios
|
||||||
|
|
||||||
|
The RS-UVPA can be used with other VHF/UHF transmitters that provide up to 1W output, including:
|
||||||
|
|
||||||
|
- Hamshield (Arduino shield radio)
|
||||||
|
- Other RS-UV3 variants
|
||||||
|
- Low-power transmitter modules
|
||||||
|
|
||||||
|
For non-RS-UV3 applications:
|
||||||
|
1. Connect TX output to RS-UVPA input
|
||||||
|
2. Connect RS-UVPA output to antenna
|
||||||
|
3. Provide PTT signal for TX/RX switching
|
||||||
|
4. Provide 8V–15V DC power
|
||||||
|
|
||||||
|
Contact HobbyPCB for detailed integration guidance.
|
||||||
|
|
||||||
|

|
---
|
||||||
|
|
||||||
|
The RS-UV3A provides multiple connection options for power, audio, control, and expansion. This page covers all physical connections on the board.
|
||||||
|
|
||||||
|
## Board Layout
|
||||||
|
|
||||||
|
The RS-UV3A has the following major connection points:
|
||||||
|
|
||||||
|
1. **VIN** — DC power input jack
|
||||||
|
2. **USB** — Micro USB for power and serial
|
||||||
|
3. **ANT** — SMA antenna connector
|
||||||
|
4. **JP1** — Arduino/serial header
|
||||||
|
5. **ICSP** — PIC programmer header
|
||||||
|
6. **AMP** — Power amplifier header
|
||||||
|
7. **I/O** — DB-9 external interface
|
||||||
|
8. **SPK/MIC** — 3.5mm TRRS jack
|
||||||
|
9. **JP2** — FTDI cable header
|
||||||
|
10. **26M** — Oscillator output
|
||||||
|
11. **PW** — Power switch header
|
||||||
|
12. **PA** — Internal PA header
|
||||||
|
13. **I/O_P** — I/O power jumper
|
||||||
|
|
||||||
|
## DC Power (VIN)
|
||||||
|
|
||||||
|
The main power input uses a 2.1mm barrel connector.
|
||||||
|
|
||||||
|
| Parameter | Value |
|
||||||
|
|-----------|-------|
|
||||||
|
| Connector | 5.5 × 2.1 mm barrel |
|
||||||
|
| Polarity | Center positive |
|
||||||
|
| Voltage | 3.5V – 16V DC |
|
||||||
|
| Protection | Reverse polarity diode |
|
||||||
|
| Recommended Fuse | 1A |
|
||||||
|
|
||||||
|
The on-board buck-boost converter provides stable power across this wide input range. Power consumption is approximately 1.6W maximum; actual current draw varies inversely with input voltage.
|
||||||
|
|
||||||
|
## Micro USB
|
||||||
|
|
||||||
|
The USB connector provides both power and serial communication.
|
||||||
|
|
||||||
|
- **Power:** 5V from USB host
|
||||||
|
- **Serial:** Driverless FTDI chip (most OS)
|
||||||
|
- **Baud Rate:** 19200 (default), configurable via `B1` command
|
||||||
|
|
||||||
|
USB and VIN power are diode-isolated—you can connect both simultaneously for backup power operation.
|
||||||
|
|
||||||
|
## Antenna (ANT)
|
||||||
|
|
||||||
|
The SMA female jack handles both TX and RX.
|
||||||
|
|
||||||
|
| Parameter | Specification |
|
||||||
|
|-----------|---------------|
|
||||||
|
| Connector | SMA female |
|
||||||
|
| Impedance | 50Ω |
|
||||||
|
| Max RF Input | -10 dBm |
|
||||||
|
| Max DC | 25V |
|
||||||
|
|
||||||
|
Internal filtering:
|
||||||
|
- **RX:** 100 MHz high-pass filter, LNA with band-equalizing filter
|
||||||
|
- **TX:** Individual low-pass filters for 2m, 1.25m, and 70cm bands
|
||||||
|
|
||||||
|

|
|
||||||
|
This guide will help you get your RS-UV3A up and running for basic voice operation.
|
||||||
|
|
||||||
|
## What You'll Need
|
||||||
|
|
||||||
|
Before powering on your RS-UV3A, gather these essentials:
|
||||||
|
|
||||||
|
1. **Antenna** or 50Ω dummy load
|
||||||
|
2. **Power source** (one of the following):
|
||||||
|
- USB cable and USB power supply/computer
|
||||||
|
- 9V battery
|
||||||
|
- 12V DC wall adapter (5.5×2.1mm barrel connector)
|
||||||
|
3. **Speaker** (or headphones)
|
||||||
|
4. **Microphone** (electret type)
|
||||||
|
5. **PTT switch** (momentary contact)
|
||||||
|
|
||||||
|
## Minimum Connections
|
||||||
|
|
||||||
|
### 1. Antenna
|
||||||
|
|
||||||
|
Connect a suitable antenna or 50Ω load to the SMA jack. The RS-UV3A is tolerant of antenna mismatches (even open or short circuits), but a well-matched antenna gives best performance and equipment longevity.
|
||||||
|
|
||||||
|
:::caution[Never transmit without a load]
|
||||||
|
While the RS-UV3A can survive momentary antenna mismatches, always connect an antenna or dummy load before transmitting.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### 2. Power
|
||||||
|
|
||||||
|
You have several options for powering the RS-UV3A:
|
||||||
|
|
||||||
|
| Method | Voltage | Notes |
|
||||||
|
|--------|---------|-------|
|
||||||
|
| **USB** | 5V | Powers board and provides serial |
|
||||||
|
| **VIN Jack** | 3.5–16V | 5.5×2.1mm barrel, center positive |
|
||||||
|
| **PW Header** | 3.5–16V | For custom installations |
|
||||||
|
|
||||||
|
The RS-UV3A includes diode protection, so USB and external power can be connected simultaneously. This provides backup power capability—connect a USB power bank to keep operating if primary power fails.
|
||||||
|
|
||||||
|
:::tip[Power Switch]
|
||||||
|
The PW header has a factory-installed jumper. Remove it and wire in a switch for on/off control.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### 3. Audio and PTT
|
||||||
|
|
||||||
|
For basic voice operation, connect:
|
||||||
|
|
||||||
|
| Connection | Signal | Notes |
|
||||||
|
|------------|--------|-------|
|
||||||
|
| **SPKR** | Speaker output | 8Ω speaker, level via VR1 |
|
||||||
|
| **MIC** | Microphone input | 3.3V bias for electret mic |
|
||||||
|
| **PTT** | Push-to-talk | Ground to transmit |
|
||||||
|
|
||||||
|
The ground pads next to each signal provide convenient connection points.
|
||||||
|
|
||||||
|
## Factory Default Settings
|
||||||
|
|
||||||
|
Out of the box, your RS-UV3A is configured for:
|
||||||
|
|
||||||
|
- **Frequency:** 146.520 MHz (2m FM simplex calling frequency)
|
||||||
|
- **Mode:** Simplex (TX and RX on same frequency)
|
||||||
|
- **Power:** High (~200 mW)
|
||||||
|
- **Squelch:** Level 3
|
||||||
|
- **Baud Rate:** 19200
|
||||||
|
|
||||||
|
At this point, you can listen on 146.52 MHz and transmit by pressing PTT!
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
To change frequencies or adjust other parameters, you'll need a serial connection:
|
||||||
|
|
||||||
|
- [Serial Setup](/getting-started/serial-setup/) — Connect to a computer for full control
|
||||||
|
- [Connections Reference](/getting-started/connections/) — Detailed pinouts for all connectors
|
||||||
|
- [Voice Operation](/guides/voice-operation/) — In-depth guide for voice communications
|
||||||
|
|
||||||
|
## Quick Test
|
||||||
|
|
||||||
|
1. Power on the RS-UV3A
|
||||||
|
2. Connect a speaker to hear receiver audio
|
||||||
|
3. Turn the squelch control (VR1) to hear background noise
|
||||||
|
4. Tune a handheld radio to 146.52 MHz and transmit
|
||||||
|
5. You should hear the signal on your RS-UV3A speaker
|
||||||
|
|
||||||
|
If you have a serial terminal connected:
|
||||||
|
|
||||||
|
```
|
||||||
|
FS146520 # Confirm frequency
|
||||||
|
SQ3 # Set squelch level
|
||||||
|
VU15 # Set volume
|
||||||
|
```

|
Full control of the RS-UV3A requires a serial connection. This guide covers the various ways to connect and configure serial communication.
|
||||||
|
|
||||||
|
## Connection Options
|
||||||
|
|
||||||
|
The RS-UV3A provides three serial connection methods:
|
||||||
|
|
||||||
|
| Method | Connector | Best For |
|
||||||
|
|--------|-----------|----------|
|
||||||
|
| **On-board USB** | Micro USB | Most users—single cable for power and control |
|
||||||
|
| **JP1 Header** | 0.1" header | Arduino and microcontroller projects |
|
||||||
|
| **JP2 Header** | 6-pin header | FTDI cable or Raspberry Pi |
|
||||||
|
| **DB-9 I/O** | DB-9 pins 7/8 | External serial devices |
|
||||||
|
|
||||||
|
:::note[Important]
|
||||||
|
JP1 and JP2 share the same internal serial port (`B1` baud setting). The DB-9 uses a separate serial port (`B2` baud setting).
|
||||||
|
:::
|
||||||
|
|
||||||
|
## On-board USB (Recommended)
|
||||||
|
|
||||||
|
The RS-UV3A Rev A includes an FTDI FT230X USB-serial chip that works without drivers on most modern operating systems.
|
||||||
|

|
||||||
|
1. Connect a micro USB cable to the RS-UV3A
|
||||||
|
2. Connect the other end to your computer
|
||||||
|
3. The board powers on and enumerates as a serial port
|
||||||
|
|
||||||
|
### Finding the Port
|
||||||
|
|
||||||
|
**Linux:**
|
||||||
|
```bash
|
||||||
|
ls /dev/ttyUSB*
|
||||||
|
# or
|
||||||
|
dmesg | grep tty
|
||||||
|
```
|
||||||
|
|
||||||
|
**macOS:**
|
||||||
|
```bash
|
||||||
|
ls /dev/tty.usbserial*
|
||||||
|
```
|
||||||
|
|
||||||
|
**Windows:**
|
||||||
|
- Open Device Manager
|
||||||
|
- Look under "Ports (COM & LPT)"
|
||||||
|
- Note the COM port number (e.g., COM3)
|
||||||
|
|
||||||
|
## Terminal Software
|
||||||
|
|
||||||
|
Use any serial terminal program to communicate with the RS-UV3A:
|
||||||
|
|
||||||
|

|
||||||
|
|----------|---------|
|
||||||
|
| Linux | `minicom`, `screen`, `picocom`, `putty` |
|
||||||
|
| macOS | `screen`, `CoolTerm`, `Serial` |
|
||||||
|
| Windows | PuTTY, Tera Term, RealTerm |
|
||||||
|
| Cross-platform | Arduino Serial Monitor, VS Code Serial Monitor |
|
||||||
|
|
||||||
|

```
|
||||||
|
|
||||||
|
Configure: `Ctrl-A` then `O` → Serial port setup → Hardware flow control: No
|
||||||
|
|
||||||
|
## Verifying Connection
|
||||||
|
|
||||||
|
Send a command to verify communication:
|
||||||
|
|
||||||
|
```
|
||||||
|
FW
|
||||||
|
```
|
||||||
|
|
||||||
|
Expected response:
|
||||||
|
```
|
||||||
|
FW: 2.4A
|
||||||
|
```
|
||||||
|
|
||||||
|
(Version number may vary)
|
||||||
|
|
||||||
|
Try a few more commands:
|
||||||
|
|
||||||
|
```
|
||||||
|
F? # Query frequency
|
||||||
|
SS # Read signal strength
|
||||||
|
VT # Read voltage
|
||||||
|
TP # Read temperature
|
||||||
|
```
|
||||||
|
|
||||||
|
## Changing Baud Rate
|
||||||
|
|
||||||
|
The RS-UV3A supports multiple baud rates:
|
||||||
|
|
||||||
|
| Code | Baud Rate |
|
||||||
|
|------|-----------|
|
||||||
|
| 0 | 1200 |
|
||||||
|
| 1 | 4800 |
|
||||||
|
| 2 | 9600 |
|
||||||
|
| 3 | 19200 (default) |
|
||||||
|
| 4 | 38400 |
|
||||||
|
| 5 | 57600 |
|
||||||
|
|
||||||
|
### Internal Serial (USB/JP1/JP2)
|
||||||
|
|
||||||
|
```
|
||||||
|
B13 # Set to 19200 (default)
|
||||||
|
B15 # Set to 57600
|
||||||
|
```
|
||||||
|
|
||||||
|
### External Serial (DB-9)
|
||||||
|
|
||||||
|
```
|
||||||
|
B23 # Set to 19200 (default)
|
||||||
|
B25 # Set to 57600
|
||||||
|
```
|
||||||
|
|
||||||
|
:::caution
|
||||||
|
Baud rate changes require a **power cycle** to take effect. After changing, you'll need to reconnect your terminal at the new baud rate.
|
||||||
|
:::
|
||||||
|
|
||||||
|
## Arduino Connection
|
||||||
|
|
||||||
|
To connect the RS-UV3A to an Arduino:
|
||||||
|
|
||||||
|
1. Install headers on JP1 (see [Connections](/getting-started/connections/))
|
||||||
|
2. Connect:
|
||||||
|
- RS-UV3A RXD → Arduino TX pin
|
||||||
|
- RS-UV3A TXD → Arduino RX pin
|
||||||
|
- RS-UV3A GND → Arduino GND
|
||||||
|
|
||||||
|
3. Use SoftwareSerial or hardware UART at 19200 baud
|
||||||
|
|
||||||
|
### Arduino Example
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
#include <SoftwareSerial.h>
|
||||||
|
|
||||||
|
SoftwareSerial radio(10, 11); // RX, TX
|
||||||
|
|
||||||
|
void setup() {
|
||||||
|
Serial.begin(9600);
|
||||||
|
radio.begin(19200);
|
||||||
|
|
||||||
|
delay(100);
|
||||||
|
radio.println("F?"); // Query frequency
|
||||||
|
}
|
||||||
|
|
||||||
|
void loop() {
|
||||||
|
if (radio.available()) {
|
||||||
|
Serial.write(radio.read());
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Logic Levels
|
||||||
|
|
||||||
|
The RS-UV3A accepts 3.3V or 5V logic inputs. Output voltage depends on the VIO pin:
|
||||||
|
|
||||||
|
- If Arduino VIN powers the RS-UV3A: outputs match Arduino logic
|
||||||
|
- For 3.3V devices (like Raspberry Pi): jumper JP1 3.3V to JP2 VIO
|
||||||
|
|
||||||
|
## Raspberry Pi Connection
|
||||||
|
|
||||||
|
Connect directly to GPIO UART:
|
||||||
|
|
||||||
|
| RS-UV3A (JP1/JP2) | Raspberry Pi |
|
||||||
|
|-------------------|--------------|
|
||||||
|
| TXD | GPIO 15 (RXD) |
|
||||||
|
| RXD | GPIO 14 (TXD) |
|
||||||
|
| GND | GND |
|
||||||
|
| 3.3V → VIO | (jumper on RS-UV3A) |
|
||||||
|
|
||||||
|
Enable UART on Raspberry Pi:
|
||||||
|
```bash
|
||||||
|
sudo raspi-config
|
||||||
|
# → Interface Options → Serial Port
|
||||||
|
# → Login shell: No
|
||||||
|
# → Serial hardware: Yes
|
||||||
|
```
|
||||||
|
|
||||||
|
## Command Syntax
|
||||||
|
|
||||||
|
All RS-UV3A commands follow these rules:
|
||||||
|
|
||||||
|
- **Not case sensitive** — `fs146520` equals `FS146520`
|
||||||
|
- **Terminated by CR** — Carriage return (ASCII 13)
|
||||||
|
- **Fixed digit counts** — Some parameters require all digits (e.g., `FS146520` not `FS14652`)
|
||||||
|
- **Query with ?** — Most commands accept `?` to query current value
|
||||||
|
|
||||||
|
### Quick Command Test
|
||||||
|
|
||||||
|
```
|
||||||
|
FS146520 # Set frequency to 146.520 MHz
|
||||||
|
F? # Query current frequency
|
||||||
|
SQ5 # Set squelch to level 5
|
||||||
|
TX1 # Transmit for 1 minute max
|
||||||
|
TX0 # Stop transmitting
|
||||||
|
```
|
||||||
|
|
||||||
|
See the [Command Reference](/reference/commands/) for the complete command list.
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### No Response to Commands
|
||||||
|
|
||||||
|
1. Check USB cable is data-capable (not charge-only)
|
||||||
|
2. Verify correct COM port
|
||||||
|
3. Confirm baud rate is 19200
|
||||||
|
4. Ensure line ending is CR (not LF or CRLF)
|
||||||
|
5. Check for loose connections
|
||||||
|
|
||||||
|
### Garbled Output
|
||||||
|
|
||||||
|
- Wrong baud rate — try 19200, then other rates
|
||||||
|
- Line ending issues — try CR only
|
||||||
|
- Noise on serial line — use shorter cables, add bypass capacitors
|
||||||
|
|
||||||
|
### USB Not Recognized
|
||||||
|
|
||||||
|
- Try a different USB cable
|
||||||
|
- Try a different USB port
|
||||||
|
- On Windows, install [FTDI drivers](https://ftdichip.com/drivers/) if needed
|
||||||
|
- Check `dmesg` output on Linux for errors

title: Beacon Operation
|
||||||
|
description: Using the RS-UV3A as an automatic CW beacon
|
||||||
|
---
|
||||||
|
|
||||||
|
The RS-UV3A has built-in beacon functionality for transmitting periodic CW identification or messages. This is useful for propagation studies, fox hunting, and repeater ID.
|
||||||
|
|
||||||
|
## Beacon Types
|
||||||
|
|
||||||
|
The RS-UV3A supports two beacon modes:
|
||||||
|
|
||||||
|
| Type | Command | Description |
|
||||||
|
|------|---------|-------------|
|
||||||
|
| **MCW** (Audio CW) | `BT` | FM carrier with CW-modulated audio tone |
|
||||||
|
| **True CW** | `BC` | On-off keyed carrier (OOK) |
|
||||||
|
|
||||||
|
### MCW vs True CW
|
||||||
|
|
||||||
|
**MCW (Modulated CW):**
|
||||||
|
- Transmits on FM frequencies
|
||||||
|
- Can be received with any FM receiver (HT, mobile radio)
|
||||||
|
- Must be used in voice portions of the band
|
||||||
|
|
||||||
|
**True CW:**
|
||||||
|
- Traditional on-off keying
|
||||||
|
- Requires a CW receiver (SSB/CW mode)
|
||||||
|
- Can be used in CW/data portions of bands
|
||||||
|
- Better range due to narrower bandwidth
|
||||||
|
|
||||||
|
## Setting Up a Beacon
|
||||||
|
|
||||||
|
### Step 1: Set the Beacon Message
|
||||||
|
|
||||||
|
```
|
||||||
|
BMWA2EUJ # Simple callsign
|
||||||
|
BMWA2EUJ BEACON # Callsign with text
|
||||||
|
BM? # Query current message
|
||||||
|
```
|
||||||
|
|
||||||
|
Maximum message length is 32 characters. Valid characters:
|
||||||
|
- Letters A–Z
|
||||||
|
- Numbers 0–9
|
||||||
|
- Punctuation: period, comma, question mark, slash
|
||||||
|
- Space
|
||||||
|
|
||||||
|
### Step 2: Set CW Parameters
|
||||||
|
|
||||||
|
```
|
||||||
|
CS15 # 15 WPM (words per minute)
|
||||||
|
CF0800 # 800 Hz tone frequency
|
||||||
|
CS? # Query speed
|
||||||
|
CF? # Query frequency
|
||||||
|
```
|
||||||
|
|
||||||
|
Speed range: 5–25 WPM
|
||||||
|
Tone range: 400–1300 Hz
|
||||||
|
|
||||||
|
### Step 3: Set the Beacon Timer
|
||||||
|
|
||||||
|
For MCW beacon:
|
||||||
|
```
|
||||||
|
BT120 # Send beacon every 120 seconds (2 minutes)
|
||||||
|
BT600 # Every 10 minutes (maximum)
|
||||||
|
BT060 # Every 60 seconds (minimum)
|
||||||
|
BT000 # Disable beacon
|
||||||
|
```
|
||||||
|
|
||||||
|
For true CW beacon:
|
||||||
|
```
|
||||||
|
BC120 # Send CW beacon every 120 seconds
|
||||||
|
BC000 # Disable beacon
|
||||||
|
```
|
||||||
|
|
||||||
|
:::note
|
||||||
|
Setting `BT` automatically disables `BC`, and vice versa. Only one beacon type can be active.
|
||||||
|
:::
|
||||||
|
|
||||||
|
## Advanced Beacon Features
|
||||||
|
|
||||||
|
### Carrier Insertion (True CW Only)
|
||||||
|
|
||||||
|
In true CW mode, you can insert unmodulated carrier segments for DF (direction finding):
|
||||||
|
|
||||||
|
```
|
||||||
|
BM#10WA2EUJ # 10 seconds of carrier, then callsign
|
||||||
|
BMWA2EUJ#05 # Callsign, then 5 seconds carrier
|
||||||
|
BM#15WA2EUJ#10 # 15s carrier, call, 10s carrier
|
||||||
|
```
|
||||||
|
|
||||||
|
The `#nn` syntax inserts `nn` seconds of unmodulated carrier (1–30 seconds).
|
||||||
|
|
||||||
|
### Message Repeat
|
||||||
|
|
||||||
|
Use `&` to repeat the message continuously during the beacon:
|
||||||
|
|
||||||
|
```
|
||||||
|
BMWA2EUJ & # Repeats "WA2EUJ" until timer expires
|
||||||
|
```
|
||||||
|
|
||||||
|
Everything after `&` is sent once at the end.
|
||||||
|
|
||||||
|
### Multi-Channel Beacons
|
||||||
|
|
||||||
|
Send beacons on multiple frequencies by storing different frequencies in memory channels:
|
||||||
|
|
||||||
|
```
|
||||||
|
# Setup channel 1
|
||||||
|
FS144275 # 2m frequency
|
||||||
|
PW1 # High power
|
||||||
|
ST1 # Save to channel 1
|
||||||
|
|
||||||
|
# Setup channel 2
|
||||||
|
FS222100 # 1.25m frequency
|
||||||
|
PW1 # High power
|
||||||
|
ST2 # Save to channel 2
|
||||||
|
|
||||||
|
# Setup channel 3
|
||||||
|
FS432100 # 70cm frequency
|
||||||
|
PW0 # Low power (different power level example)
|
||||||
|
ST3 # Save to channel 3
|
||||||
|
|
||||||
|
# Enable multi-channel beacon
|
||||||
|
MC3 # Cycle through channels 1-3
|
||||||
|
BT120 # Beacon every 2 minutes
|
||||||
|
```
|
||||||
|
|
||||||
|
The beacon will:
|
||||||
|
1. Recall channel 1, transmit beacon
|
||||||
|
2. Wait 2 minutes
|
||||||
|
3. Recall channel 2, transmit beacon
|
||||||
|
4. Wait 2 minutes
|
||||||
|
5. Recall channel 3, transmit beacon
|
||||||
|
6. Wait 2 minutes
|
||||||
|
7. Return to channel 1, repeat...
|
||||||
|
|
||||||
|
To disable multi-channel mode:
|
||||||
|
```
|
||||||
|
MC0 # Single channel beacon
|
||||||
|
```
|
||||||
|
|
||||||
|
## CW Sidetone
|
||||||
|
|
||||||
|
Enable sidetone to hear the CW through the speaker:
|
||||||
|
|
||||||
|
```
|
||||||
|
SD1 # Sidetone on
|
||||||
|
SD0 # Sidetone off (default)
|
||||||
|
```
|
||||||
|
|
||||||
|
The sidetone level follows the DTMF/CW gain setting:
|
||||||
|
|
||||||
|
```
|
||||||
|
GT08 # Default tone gain
|
||||||
|
GT12 # Louder tones
|
||||||
|
```
|
||||||
|
|
||||||
|
## Manual CW Transmission
|
||||||
|
|
||||||
|
Send CW messages on demand:
|
||||||
|
|
||||||
|
```
|
||||||
|
CTWA2EUJ # Send "WA2EUJ" as MCW (audio)
|
||||||
|
CWWA2EUJ # Send "WA2EUJ" as true CW
|
||||||
|
```
|
||||||
|
|
||||||
|
Maximum manual message length is 28 characters.
|
||||||
|
|
||||||
|
## Fox Hunting Setup
|
||||||
|
|
||||||
|
For a hidden transmitter (fox hunt):
|
||||||
|
|
||||||
|
```
|
||||||
|
FS146565 # Out-of-the-way frequency
|
||||||
|
BMFOX # Simple message
|
||||||
|
BC060 # Beacon every minute
|
||||||
|
PW0 # Low power for nearby hunting
|
||||||
|
ST0 # Save settings
|
||||||
|
```
|
||||||
|
|
||||||
|
For longer-range hunts, use true CW with carrier segments:
|
||||||
|
|
||||||
|
```
|
||||||
|
BM#30FOX # 30 seconds carrier + "FOX"
|
||||||
|
BC120 # Every 2 minutes
|
||||||
|
PW1 # High power
|
||||||
|
```
|
||||||
|
|
||||||
|
## Propagation Beacon
|
||||||
|
|
||||||
|
For propagation studies across multiple bands:
|
||||||
|
|
||||||
|
```
|
||||||
|
# Store frequencies for each band
|
||||||
|
FS144280
|
||||||
|
ST1
|
||||||
|
|
||||||
|
FS222100
|
||||||
|
ST2
|
||||||
|
|
||||||
|
FS432400
|
||||||
|
ST3
|
||||||
|
|
||||||
|
# Configure beacon
|
||||||
|
BMWA2EUJ/B QTH # Beacon message with locator
|
||||||
|
CS12 # Slow speed for weak signal copy
|
||||||
|
MC3 # Three bands
|
||||||
|
BC300 # Every 5 minutes
|
||||||
|
```
|
||||||
|
|
||||||
|
## Beacon with External Controller
|
||||||
|
|
||||||
|
For more sophisticated beacon applications (APRS beacons, GPS-based beacons), connect an Arduino or Raspberry Pi:
|
||||||
|
|
||||||
|
1. Connect MCU to JP1 (serial + control)
|
||||||
|
2. Use `CT` or `CW` commands to send messages
|
||||||
|
3. Use `TX1`/`TX0` for transmitter control
|
||||||
|
4. MCU handles timing and message generation
|
||||||
|
|
||||||
|
This allows:
|
||||||
|
- GPS-derived position beacons
|
||||||
|
- Temperature/telemetry beacons
|
||||||
|
- Conditional beacons (only when conditions met)
|
||||||
|
|
||||||
|
## Stopping a Beacon
|
||||||
|
|
||||||
|
```
|
||||||
|
BT000 # Disable MCW beacon
|
||||||
|
BC000 # Disable CW beacon
|
||||||
|
```
|
||||||
|
|
||||||
|
Or simply power cycle the RS-UV3A if beacon was not saved with `ST0`.
|
||||||
|
|
||||||
|
## Complete Beacon Example

description: How to update the RS-UV3A firmware using the bootloader
|
||||||
|
---
|
||||||
|
|
||||||
|
The RS-UV3A firmware can be updated using a built-in bootloader. This guide covers the upgrade process.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
You'll need:
|
||||||
|
|
||||||
|
1. **RS-UV3A** connected via USB or serial
|
||||||
|
2. **Windows PC** (bootloader software is Windows-only)
|
||||||
|
3. **mikroBootloader 2.3** software
|
||||||
|
4. **Latest firmware file** (.HEX format) from HobbyPCB
|
||||||
|
|
||||||
|
## Getting the Software
|
||||||
|
|
||||||
|
### Bootloader Software
|
||||||
|
|
||||||
|
Search for and download `mikroBootloader2.3.zip`. This is a standalone tool from MikroElektronika that doesn't require installation.
|
||||||
|
|
||||||
|
### Firmware File
|
||||||
|
|
||||||
|
Download the latest `RS_UV3_FIRMWARE_VX-X.HEX` from the [HobbyPCB Files](https://sites.google.com/site/hobbypcbrsuv3awiki/) page.
|
||||||
|
|
||||||
|
## Upgrade Process
|
||||||
|
|
||||||
|
### Step 1: Configure the Bootloader
|
||||||
|
|
||||||
|
1. Extract and run `mikroBootloader.exe`
|
||||||
|
2. Click **Change Settings**
|
||||||
|
3. Set **Port** to your RS-UV3A's COM port
|
||||||
|
4. Set **Baud rate** to **115200**
|
||||||
|
5. Leave other settings at defaults
|
||||||
|
6. Click **OK**
|
||||||
|
|
||||||
|
:::tip[Finding Your COM Port]
|
||||||
|
On Windows, check Device Manager → Ports (COM & LPT) to find the RS-UV3A.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### Step 2: Enter Bootloader Mode
|
||||||
|
|
||||||
|
The RS-UV3A must be listening for the bootloader before you can connect.
|
||||||
|
|
||||||
|
**Method 1: BL Command (Normal Operation)**
|
||||||
|
|
||||||
|
If your RS-UV3A is working and responsive:
|
||||||
|
|
||||||
|
1. Open a terminal program (PuTTY, Tera Term)
|
||||||
|
2. Connect at 19200 baud
|
||||||
|
3. Send the command:
|
||||||
|
```
|
||||||
|
BL
|
||||||
|
```
|
||||||
|
4. **Close the terminal program** (important!)
|
||||||
|
|
||||||
|
The RS-UV3A is now waiting for the bootloader. It will wait indefinitely.
|
||||||
|
|
||||||
|
**Method 2: ICSP Jumper (If Unresponsive)**
|
||||||
|
|
||||||
|
If the RS-UV3A won't respond to commands (corrupted firmware):
|
||||||
|
|
||||||
|
1. Power off the RS-UV3A
|
||||||
|
2. Place a jumper on the ICSP header:
|
||||||
|
- Pins 1-2 for USB/JP1 serial upload
|
||||||
|
- Pins 4-5 for DB-9 serial upload
|
||||||
|
3. Power on the RS-UV3A
|
||||||
|
|
||||||
|
The RS-UV3A will boot directly into bootloader mode.
|
||||||
|
|
||||||
|
### Step 3: Connect and Upload
|
||||||
|
|
||||||
|
1. Ensure your terminal program is **closed**
|
||||||
|
2. In mikroBootloader, ensure **PIC18** is selected in "Select MCU"
|
||||||
|
3. Click **Connect**
|
||||||
|
4. You should see "Connected" in the History window
|
||||||
|
5. Click **Browse** and select the firmware .HEX file
|
||||||
|
6. Click **Begin uploading**
|
||||||
|
7. Wait for the upload to complete (progress bar fills)
|
||||||
|
|
||||||
|
### Step 4: Restart
|
||||||
|
|
||||||
|
1. Power cycle the RS-UV3A
|
||||||
|
2. Connect with a terminal program
|
||||||
|
3. Verify the new version:
|
||||||
|
```
|
||||||
|
FW
|
||||||
|
```
|
||||||
|
|
||||||
|
You should see the new firmware version reported.
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### "No response from device"
|
||||||
|
|
||||||
|
- Verify the COM port is correct
|
||||||
|
- Ensure the terminal program is closed
|
||||||
|
- Check that you sent `BL` command successfully
|
||||||
|
- Try the ICSP jumper method
|
||||||
|
|
||||||
|
### Upload Fails Partway
|
||||||
|
|
||||||
|
- Check USB cable connection
|
||||||
|
- Try a different USB port
|
||||||
|
- Reduce cable length
|
||||||
|
- Ensure stable power supply
|
||||||
|
|
||||||
|
### RS-UV3A Unresponsive After Failed Upload
|
||||||
|
|
||||||
|
Use the ICSP jumper method to force bootloader mode, then re-upload.
|
||||||
|
|
||||||
|
### Wrong Bootloader Baud Rate
|
||||||
|
|
||||||
|
The bootloader always runs at 115200 baud, regardless of the `B1` setting. Don't confuse this with the normal operating baud rate (default 19200).
|
||||||
|
|
||||||
|
## After Upgrading
|
||||||
|
|
||||||
|
After a successful upgrade:
|
||||||
|
|
||||||
|
1. Check version: `FW`
|
||||||
|
2. Your saved settings should be retained
|
||||||
|
3. If settings were lost, restore defaults: `FD1`
|
||||||
|
4. Reconfigure as needed
|
||||||
|
5. Save settings: `ST0`
|
||||||
|
|
||||||
|
## Version History
|
||||||
|
|
||||||
|
Check the HobbyPCB wiki for release notes on each firmware version. Typical improvements include:
|
||||||
|
- New commands
|
||||||
|
- Bug fixes
|
||||||
|
- Improved receiver performance
|
||||||
|
- Additional features
|
||||||
|
|
||||||
|
## Important Notes
|
||||||
|
|
||||||
|
:::caution[Don't Interrupt the Upload]
|
||||||
|
Never power off or disconnect during the upload process. This can leave the RS-UV3A in an unresponsive state requiring the ICSP jumper recovery method.
|
||||||
|
:::
|
||||||
|
|
||||||
|
:::note[Windows Only]
|
||||||
|
The mikroBootloader software only runs on Windows. For Linux/Mac users, a Windows VM or separate Windows PC is required for firmware updates.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### Exiting Bootloader Mode Without Uploading
|
||||||
|
|
||||||
|
If you accidentally entered bootloader mode (`BL` command) and want to exit without uploading:
|
||||||
|
- Simply power cycle the RS-UV3A
|
||||||
|
- It will boot normally (unless you have an ICSP jumper installed)
|
||||||
|
|
||||||
|
## ICSP Header Pinout
|
||||||
|
|
||||||
|
For reference, the ICSP header pins (when viewed from the top):
|
||||||
|
|
||||||
|
```
|
||||||
|
1 2
|
||||||
|
3 4
|
||||||
|
5 6
|
||||||
|
```
|
||||||
|
|
||||||
|
- **Pins 1-2 jumper:** Bootloader on USB/JP1 serial
|
||||||
|
- **Pins 4-5 jumper:** Bootloader on DB-9 serial
|
||||||
|
|
||||||
|
Remove the jumper after successful upload to resume normal operation.

|
description: Using the RS-UV3A for packet radio and APRS
|
||||||
|
---
|
||||||
|
|
||||||
|
The RS-UV3A supports packet radio and APRS (Automatic Packet Reporting System) operations when connected to a TNC (Terminal Node Controller) or software modem.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The RS-UV3A provides:
|
||||||
|
- **TX audio input** for packet tones from the TNC
|
||||||
|
- **RX audio output** for received signals to the TNC
|
||||||
|
- **PTT control** for keying the transmitter
|
||||||
|
- **COR output** for carrier-operated relay
|
||||||
|
|
||||||
|
## Hardware Connections
|
||||||
|
|
||||||
|
### Using the DB-9 I/O Connector
|
||||||
|
|
||||||
|
Connect your TNC or sound card modem to the DB-9:
|
||||||
|
|
||||||
|
| DB-9 Pin | Signal | TNC Connection |
|
||||||
|
|----------|--------|----------------|
|
||||||
|
| 1 | TX Audio In | TNC TX audio out |
|
||||||
|
| 2 | PTT | TNC PTT output |
|
||||||
|
| 3 | GND | TNC ground |
|
||||||
|
| 4 | RX Audio Out | TNC RX audio in |
|
||||||
|
| 5 | COR | TNC COR/DCD input (optional) |
|
||||||
|
|
||||||
|
:::danger[TTL Levels!]
|
||||||
|
The DB-9 is NOT RS-232! Use only TTL (3.3V/5V) devices or a level converter.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### Audio Level Adjustment
|
||||||
|
|
||||||
|
1. **TX Audio:** Adjust VR3 on the board for proper deviation (typically 3–3.5 kHz for packet)
|
||||||
|
2. **RX Audio:** Use the `VU` command to set receiver audio level
|
||||||
|
|
||||||
|
```
|
||||||
|
VU15 # Good starting point for DTMF/packet decode
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration for Packet
|
||||||
|
|
||||||
|
### Basic Setup for 1200 Baud
|
||||||
|
|
||||||
|
Standard 2m packet uses 144.39 MHz (APRS) or 145.01 MHz (general packet):
|
||||||
|
|
||||||
|
```
|
||||||
|
FS144390 # APRS frequency
|
||||||
|
AF0 # Wide audio filter for data
|
||||||
|
DP0 # Disable pre/de-emphasis for flat response
|
||||||
|
SQ3 # Moderate squelch
|
||||||
|
ST0 # Save as defaults
|
||||||
|
```
|
||||||
|
|
||||||
|
### APRS Digipeater/iGate Configuration
|
||||||
|
|
||||||
|
For unattended operation:
|
||||||
|
|
||||||
|
```
|
||||||
|
FS144390 # 144.39 MHz
|
||||||
|
TM0 # No tone squelch
|
||||||
|
SQ3 # Open on moderately weak signals
|
||||||
|
AF0 # Wide audio bandwidth
|
||||||
|
DP0 # Flat audio response
|
||||||
|
TO000 # Disable timeout (TNC controls TX)
|
||||||
|
ST0 # Save settings
|
||||||
|
```
|
||||||
|
|
||||||
|
## COR (Carrier Operated Relay)
|
||||||
|
|
||||||
|
The DB-9 pin 5 provides a COR output:
|
||||||
|
- **Low (ground)** when squelch is open
|
||||||
|
- **Open circuit** when squelch is closed
|
||||||
|
|
||||||
|
This can signal the TNC that a carrier is present, useful for collision avoidance in packet operations.
|
||||||
|
|
||||||
|
### COR Inhibit
|
||||||
|
|
||||||
|
After transmitting, there's often a burst of noise as the receiver recovers. Use COR inhibit to prevent false DCD triggers:
|
||||||
|
|
||||||
|
```
|
||||||
|
CO0100 # 100 ms COR inhibit after TX
|
||||||
|
CO0200 # 200 ms inhibit
|
||||||
|
CO? # Query current setting
|
||||||
|
```
|
||||||
|
|
||||||
|
## External Serial for TNC Control
|
||||||
|
|
||||||
|
If your TNC needs to send commands to the RS-UV3A, configure the DB-9 serial:
|
||||||
|
|
||||||
|
```
|
||||||
|
EX1 # Enable serial on E_TX/E_RX pins
|
||||||
|
B23 # Set external serial to 19200 baud
|
||||||
|
```
|
||||||
|
|
||||||
|
Now pins 7 (E_TX) and 8 (E_RX) function as a TTL serial port.
|
||||||
|
|
||||||
|
## Using with Software TNCs
|
||||||
|
|
||||||
|
### Direwolf on Linux
|
||||||
|
|
||||||
|
Connect the RS-UV3A to a USB sound card:
|
||||||
|
|
||||||
|
```
|
||||||
|
# direwolf.conf
|
||||||
|
ADEVICE plughw:1,0
|
||||||
|
CHANNEL 0
|
||||||
|
MYCALL N0CALL-1
|
||||||
|
MODEM 1200
|
||||||
|
PTT /dev/ttyUSB0 RTS # If using RS-UV3A serial for PTT
|
||||||
|
```
|
||||||
|
|
||||||
|
### SoundModem on Windows
|
||||||
|
|
||||||
|
1. Connect RS-UV3A audio to sound card line in/out
|
||||||
|
2. Configure SoundModem with your sound card
|
||||||
|
3. Use a serial port (or VOX) for PTT
|
||||||
|
|
||||||
|
## Channel Bandwidth
|
||||||
|
|
||||||
|
Standard packet uses 25 kHz channel spacing:
|
||||||
|
|
||||||
|
```
|
||||||
|
BW1 # 25 kHz bandwidth (default)
|
||||||
|
```
|
||||||
|
|
||||||
|
For narrow-band packet environments:
|
||||||
|
|
||||||
|
```
|
||||||
|
BW0 # 12.5 kHz bandwidth
|
||||||
|
```
|
||||||
|
|
||||||
|
:::note
|
||||||
|
Bandwidth changes require a power cycle to take effect.
|
||||||
|
:::
|
||||||
|
|
||||||
|
## Multiple Frequency Operation
|
||||||
|
|
||||||
|
Store different packet frequencies in memory channels:
|
||||||
|
|
||||||
|
```
|
||||||
|
FS144390 # APRS
|
||||||
|
ST1 # Save to channel 1
|
||||||
|
|
||||||
|
FS145010 # General packet
|
||||||
|
ST2 # Save to channel 2
|
||||||
|
|
||||||
|
FS144990 # Alternate
|
||||||
|
ST3 # Save to channel 3
|
||||||
|
```
|
||||||
|
|
||||||
|
Switch channels via serial:
|
||||||
|
|
||||||
|
```
|
||||||
|
RC1 # Recall APRS frequency
|
||||||
|
RC2 # Recall general packet
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting Packet
|
||||||
|
|
||||||
|
### Not Decoding Packets
|
||||||
|
|
||||||
|
1. **Check audio level:** `VU15` is a good starting point
|
||||||
|
2. **Disable filters:** `AF0` and `DP0` for flat response
|
||||||
|
3. **Check squelch:** `SQ2` or `SQ3` for reliable opening
|
||||||
|
4. **Verify frequency:** `F?` to confirm
|
||||||
|
|
||||||
|
### TX Not Working
|
||||||
|
|
||||||
|
1. **Verify PTT:** Ground pin 2 should key TX
|
||||||
|
2. **Check audio:** Use a speaker to verify TNC is sending tones
|
||||||
|
3. **Adjust deviation:** VR3 controls TX audio level
|
||||||
|
|
||||||
|
### Audio Distortion
|
||||||
|
|
||||||
|
1. **TX too hot:** Turn down TNC output or VR3
|
||||||
|
2. **RX overdriven:** Reduce `VU` setting
|
||||||
|
3. **Check filters:** Try `AF1`/`AF0`, `DP1`/`DP0` combinations
|
||||||
|
|
||||||
|
## 9600 Baud Considerations
|
||||||
|
|
||||||
|
The RS-UV3A Rev A can support 9600 baud packet, but requires careful setup:
|
||||||
|
|
||||||
|
- Use wide bandwidth mode (`BW1`)
|
||||||
|
- Disable all audio filtering (`AF0`, `HP0`, `DP0`)
|
||||||
|
- Adjust audio levels carefully—9600 baud is more sensitive to deviation errors
|
||||||
|
- VR3 adjustment is critical for proper deviation
|
||||||
|
|
||||||
|
:::caution
|
||||||
|
9600 baud operation is more demanding than 1200 baud. Some experimentation may be required for reliable operation.
|
||||||
|
:::
|
||||||
|
|
||||||
|
## Complete APRS Setup Example
|
||||||
|
|
||||||
|
For a typical APRS tracker/digipeater:
|
||||||
|
|
||||||
|
```
|
||||||
|
# Set frequency and save
|
||||||
|
FS144390 # APRS frequency
|
||||||
|
|
||||||
|
# Optimize for data
|
||||||
|
AF0 # Wide audio
|
||||||
|
DP0 # Flat response
|
||||||
|
|
||||||
|
# Squelch and volume
|
||||||
|
SQ3 # Moderate squelch
|
||||||
|
VU15 # Good decode level
|
||||||
|
|
||||||
|
# TX settings
|
||||||
|
PW1 # High power
|
||||||
|
TO060 # 60 second timeout (safety)
|
||||||
|
CO0150 # 150 ms COR inhibit
|
||||||
|
|
||||||
|
# Save as defaults
|
||||||
|
ST0
|
||||||
|
```
|
||||||
|
|
||||||
|
Then connect your TNC, configure it with your callsign and path, and you're ready for APRS!

description: Using two RS-UV3A boards for full duplex operation
|
||||||
|
---
|
||||||
|
|
||||||
|
A single RS-UV3A cannot transmit and receive simultaneously. However, two RS-UV3As can be combined to create a full-duplex system for repeater or satellite communications.
|
||||||
|
|
||||||
|
## Full Duplex Configuration
|
||||||
|
|
||||||
|
### Hardware Setup
|
||||||
|
|
||||||
|
You'll need:
|
||||||
|
- Two RS-UV3A boards
|
||||||
|
- Two antennas (with sufficient isolation)
|
||||||
|
- Shared power supply
|
||||||
|
- Audio interconnection between boards
|
||||||
|
|
||||||
|
**Basic wiring:**
|
||||||
|
|
||||||
|
| RX Board | TX Board |
|
||||||
|
|----------|----------|
|
||||||
|
| RX Audio Out (DB-9 pin 4) | TX Audio In (DB-9 pin 1) |
|
||||||
|
| COR Out (DB-9 pin 5) | PTT (DB-9 pin 2) |
|
||||||
|
| Ground | Ground |
|
||||||
|
|
||||||
|
The COR-to-PTT connection automatically keys the TX board when the RX board hears a signal.
|
||||||
|
|
||||||
|
### Frequency Configuration
|
||||||
|
|
||||||
|
**Repeater example (2m input, 70cm output):**
|
||||||
|
|
||||||
|
*RX Board:*
|
||||||
|
```
|
||||||
|
FS146940 # 2m input frequency
|
||||||
|
TF10000 # 100.0 Hz CTCSS (input tone)
|
||||||
|
TM2 # Require tone to open squelch
|
||||||
|
SQ4 # Moderate squelch
|
||||||
|
```
|
||||||
|
|
||||||
|
*TX Board:*
|
||||||
|
```
|
||||||
|
FS446100 # 70cm output frequency
|
||||||
|
TF10000 # 100.0 Hz CTCSS (output tone) - optional
|
||||||
|
TM1 # Encode tone on TX
|
||||||
|
PW1 # High power
|
||||||
|
```
|
||||||
|
|
||||||
|

||||||
|
The RS-UV3A includes several features specifically for repeater operation.
|
||||||
|
|
||||||
|
### Hang Time
|
||||||
|
|
||||||
|
Keep the transmitter keyed briefly after the input signal drops:
|
||||||
|
|
||||||
|
```
|
||||||
|
HT1000 # 1000 ms (1 second) hang time
|
||||||
|
HT2000 # 2 second hang time
|
||||||
|
HT0000 # No hang time (immediate drop)
|
||||||
|
HT? # Query current setting
|
||||||
|
```
|
||||||
|
|
||||||
|
Range: 0–5000 ms
|
||||||
|
|
||||||
|
### CW Identification
|
||||||
|
|
||||||
|
FCC requires repeaters to identify at least every 10 minutes. Configure automatic CW ID:
|
||||||
|
|
||||||
|
```
|
||||||
|
CLWA2EUJ # Set callsign (15 characters max)
|
||||||
|
IT600 # ID every 600 seconds (10 minutes)
|
||||||
|
CS15 # 15 WPM CW speed
|
||||||
|
CF0750 # 750 Hz CW tone
|
||||||
|
```
|
||||||
|
|
||||||
|
The CW ID is sent after the current transmission ends, not interrupting conversations.
|
||||||
|
|
||||||
|
### Timeout Timer
|
||||||
|
|
||||||
|
Prevent stuck transmitters from tying up the repeater:
|
||||||
|
|
||||||
|
```
|
||||||
|
TO180 # 3 minute timeout
|
||||||
|
TG TIMEOUT # Message to send on timeout
|
||||||
|
```
|
||||||
|
|
||||||
|
When a user exceeds the timeout, the repeater sends the timeout message in CW and unkeys.
|
||||||
|
|
||||||
|
### Courtesy Beep
|
||||||
|
|
||||||
|
Signal users that the repeater is ready for the next transmission:
|
||||||
|
|
||||||
|
```
|
||||||
|
CB0 # No courtesy beep (default)
|
||||||
|
CB1 # Low tone beep
|
||||||
|
CB2 # High tone beep
|
||||||
|
CB3 # High/low beep
|
||||||
|
CB4 # Two-tone beep
|
||||||
|
```
|
||||||
|
|
||||||
|
The courtesy beep sounds after the hang time expires.
|
||||||
|
|
||||||
|
### COR Inhibit
|
||||||
|
|
||||||
|
Prevent receiver squelch noise from keying the transmitter after TX drops:
|
||||||
|
|
||||||
|
```
|
||||||
|
CO0200 # 200 ms inhibit after TX
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Satellite Communications
|
||||||
|
|
||||||
|
For satellite work, configure one RS-UV3A for uplink and one for downlink.
|
||||||
|
|
||||||
|
**Example for a 2m uplink / 70cm downlink satellite:**
|
||||||
|
|
||||||
|
*Uplink Board:*
|
||||||
|
```
|
||||||
|
FS145980 # Uplink frequency
|
||||||
|
TM1 # Encode any required tone
|
||||||
|
PW1 # High power for satellite
|
||||||
|
```
|
||||||
|
|
||||||
|
*Downlink Board:*
|
||||||
|
```
|
||||||
|
FS435800 # Downlink frequency
|
||||||
|
SQ2 # Sensitive squelch
|
||||||
|
VU20 # Good volume for weak signals
|
||||||
|
```
|
||||||
|
|
||||||
|
### Doppler Considerations
|
||||||
|
|
||||||
|
Satellite frequencies shift due to Doppler effect. You'll need to adjust frequencies during the pass:
|
||||||
|
- Use a tracking program to calculate Doppler
|
||||||
|
- Send frequency commands via serial as the pass progresses
|
||||||
|
- Or use an Arduino to automate frequency updates
|
||||||
|
|
||||||
|
```
|
||||||
|
# Example Doppler correction commands
|
||||||
|
FR435804 # Adjust downlink as satellite approaches
|
||||||
|
FR435800 # Nominal at TCA
|
||||||
|
FR435796 # Adjust as satellite recedes
|
||||||
|
```
|
||||||
|
|
||||||
|
## Cross-Band Repeat
|
||||||
|
|
||||||
|
A simpler configuration where you repeat between two bands:
|
||||||
|
|
||||||
|
**2m to 70cm:**
|
||||||
|
|
||||||
|
*2m Board:*
|
||||||
|
```
|
||||||
|
FS146520 # 2m simplex
|
||||||
|
COR Out → TX Board PTT
|
||||||
|
RX Audio → TX Board TX Audio
|
||||||
|
```
|
||||||
|
|
||||||
|
*70cm Board:*
|
||||||
|
```
|
||||||
|
FS446000 # 70cm simplex
|
||||||
|
TX triggered by 2m board COR
|
||||||
|
```
|
||||||
|
|
||||||
|
This allows extending range between a 2m mobile and a 70cm HT, for example.
|
||||||
|
|
||||||
|
## Important Considerations
|
||||||
|
|
||||||
|
### Antenna Isolation
|
||||||
|
|
||||||
|
For full-duplex operation, the TX and RX antennas must have sufficient isolation to prevent the TX signal from desensing or damaging the RX:
|
||||||
|
|
||||||
|
- **Physical separation:** Different poles, opposite sides of building
|
||||||
|
- **Frequency separation:** Different bands provide natural isolation
|
||||||
|
- **Filtering:** Cavity filters or duplexers for same-band operation
|
||||||
|
|
||||||
|
:::danger[Same-Band Full Duplex]
|
||||||
|
Operating a repeater with input and output on the same band (e.g., both 2m) requires expensive cavity duplexers. The RS-UV3A alone cannot provide sufficient isolation.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### Power Supply
|
||||||
|
|
||||||
|
Both boards can share a power supply, but ensure adequate current capacity:
|
||||||
|
- Two boards: ~3.5W maximum during TX
|
||||||
|
- If using RS-UVPA amplifiers: plan for up to 30W total
|
||||||
|
|
||||||
|
### Cooling
|
||||||
|
|
||||||
|
Extended TX duty cycles may require additional cooling. The RS-UV3A will read its temperature:
|
||||||
|
|
||||||
|
```
|
||||||
|
TP # Read PCB temperature
|
||||||
|
```
|
||||||
|
|
||||||
|
If temperatures exceed 60°C, consider adding airflow or heatsinking.
|
||||||
|
|
||||||
|
## Controller Integration
|
||||||
|
|
||||||
|
For more sophisticated repeater control, interface both RS-UV3As to a repeater controller or Raspberry Pi:
|
||||||
|
|
||||||
|
1. Connect both boards via USB (each gets its own COM port)
|
||||||
|
2. Use serial commands for:
|
||||||
|
- Frequency changes
|
||||||
|
- Power control
|
||||||
|
- Status monitoring
|
||||||
|
- Remote programming
|
||||||
|
|
||||||
|
This enables features like:
|
||||||
|
- DTMF remote control
|
||||||
|
- Internet linking (EchoLink, IRLP)
|
||||||
|
- Weather announcements
|
||||||
|
- Scheduled operations

description: Using the RS-UV3A for voice communications
|
||||||
|
---
|
||||||
|
|
||||||
|
This guide covers setting up the RS-UV3A for voice communications, including simplex operation, repeater access, and tone squelch configuration.
|
||||||
|
|
||||||
|
## Basic Voice Setup
|
||||||
|
|
||||||
|
For voice operation you need:
|
||||||
|
|
||||||
|
1. **Antenna** connected to SMA jack
|
||||||
|
2. **Power** via USB or VIN
|
||||||
|
3. **Speaker** connected to SPKR pads or SPK/MIC jack
|
||||||
|
4. **Microphone** (electret) connected to MIC pad
|
||||||
|
5. **PTT switch** connected to PTT pad
|
||||||
|
|
||||||
|
## Setting Frequencies
|
||||||
|
|
||||||
|
### Simplex Operation
|
||||||
|
|
||||||
|
For simplex (same frequency TX and RX), use the `FS` command:
|
||||||
|
|
||||||
|
```
|
||||||
|
FS146520 # 146.520 MHz (2m FM calling)
|
||||||
|
FS223500 # 223.500 MHz (1.25m FM calling)
|
||||||
|
FS446000 # 446.000 MHz (70cm FM calling)
|
||||||
|
```
|
||||||
|
|
||||||
|
:::tip[Frequency Format]
|
||||||
|
Always use 6 digits for frequency in kHz. For example, 146.52 MHz = `146520` kHz.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### Repeater Operation (Split Frequencies)
|
||||||
|
|
||||||
|
Use the `FD` (down) or `FU` (up) commands for standard repeater offsets:
|
||||||
|
|
||||||
|
```
|
||||||
|
FD146940 # RX 146.940, TX 146.340 (600 kHz down)
|
||||||
|
FU147060 # RX 147.060, TX 147.660 (600 kHz up)
|
||||||
|
```
|
||||||
|
|
||||||
|
Standard offsets by band:
|
||||||
|
- **2m:** ±600 kHz
|
||||||
|
- **1.25m:** ±1600 kHz
|
||||||
|
- **70cm:** ±5000 kHz
|
||||||
|
|
||||||
|
For non-standard splits, set TX and RX separately:
|
||||||
|
|
||||||
|
```
|
||||||
|
FR146940 # Set RX frequency
|
||||||
|
FT146340 # Set TX frequency
|
||||||
|
```
|
||||||
|
|
||||||
|
## Volume and Audio
|
||||||
|
|
||||||
|
### Receiver Volume
|
||||||
|
|
||||||
|
The volume can be adjusted two ways:
|
||||||
|
|
||||||
|
1. **Hardware:** Turn VR1 potentiometer on the board
|
||||||
|
2. **Software:** Use the `VU` command (0–39, in 1 dB steps)
|
||||||
|
|
||||||
|
```
|
||||||
|
VU15 # Set volume to 15 (recommended for DTMF decode)
|
||||||
|
VU20 # Increase volume
|
||||||
|
VU? # Query current volume
|
||||||
|
```
|
||||||
|
|
||||||
|
### Audio Filters
|
||||||
|
|
||||||
|
The RS-UV3A has switchable audio filters:
|
||||||
|
|
||||||
|
| Command | Filter | Passband |
|
||||||
|
|---------|--------|----------|
|
||||||
|
| `AF1` | Low-pass ON | 300–2500 Hz |
|
||||||
|
| `AF0` | Low-pass OFF | 300–5500 Hz |
|
||||||
|
| `HP1` | High-pass ON | Higher low corner |
|
||||||
|
| `HP0` | High-pass OFF | Lower low corner |
|
||||||
|
|
||||||
|
For natural-sounding voice, use the defaults (`AF1`, `HP1`). For data modes, you may want wider audio (`AF0`).
|
||||||
|
|
||||||
|
### Microphone Gain
|
||||||
|
|
||||||
|
Adjust microphone sensitivity with the `GM` command:
|
||||||
|
|
||||||
|
```
|
||||||
|
GM10 # Default gain (10)
|
||||||
|
GM15 # Maximum gain
|
||||||
|
GM05 # Lower gain for hot mics
|
||||||
|
GM? # Query current setting
|
||||||
|
```
|
||||||
|
|
||||||
|
Range is 0–15 in 2 dB steps.
|
||||||
|
|
||||||
|
## Squelch Settings
|
||||||
|
|
||||||
|
### RSSI Squelch
|
||||||
|
|
||||||
|
The basic squelch uses received signal strength:
|
||||||
|
|
||||||
|
```
|
||||||
|
SQ3 # Default, opens on moderate signals
|
||||||
|
SQ0 # Always open (listen to noise)
|
||||||
|
SQ9 # Very tight (strong signals only)
|
||||||
|
SQ? # Query current level
|
||||||
|
```
|
||||||
|
|
||||||
|
For extended range (weak signal work), enable high squelch range:
|
||||||
|
|
||||||
|
```
|
||||||
|
SR1 # Add 30 dB to squelch setting
|
||||||
|
SR0 # Normal range (default)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Checking Squelch Status
|
||||||
|
|
||||||
|
Query whether the squelch is currently open:
|
||||||
|
|
||||||
|
```
|
||||||
|
SO # Returns SO: 0 (closed) or SO: 1 (open)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Tone Squelch (CTCSS/PL)
|
||||||
|
|
||||||
|
Many repeaters require CTCSS (Continuous Tone-Coded Squelch System) tones.
|
||||||
|
|
||||||
|
### Setting the Tone Frequency
|
||||||
|
|
||||||
|
```
|
||||||
|
TF10000 # 100.0 Hz (multiply desired Hz by 100)
|
||||||
|
TF13180 # 131.8 Hz
|
||||||
|
TF08850 # 88.5 Hz
|
||||||
|
TF? # Query current tone
|
||||||
|
```
|
||||||
|
|
||||||
|
Common CTCSS frequencies: 67.0, 71.9, 74.4, 77.0, 79.7, 82.5, 85.4, 88.5, 91.5, 94.8, 97.4, 100.0, 103.5, 107.2, 110.9, 114.8, 118.8, 123.0, 127.3, 131.8, 136.5, 141.3, 146.2, 151.4, 156.7, 162.2, 167.9, 173.8, 179.9, 186.2, 192.8, 203.5
|
||||||
|
|
||||||
|
### Tone Mode
|
||||||
|
|
||||||
|
Control when tones are transmitted/required:
|
||||||
|
|
||||||
|
```
|
||||||
|
TM0 # Off (default)
|
||||||
|
TM1 # TX only (encode tone on transmit)
|
||||||
|
TM2 # TX and RX (encode + tone squelch)
|
||||||
|
```
|
||||||
|
|
||||||
|
- **TM1:** Use when the repeater requires a PL tone to access but you want to hear all traffic
|
||||||
|
- **TM2:** Use when you only want to hear stations with your tone (tone squelch)
|
||||||
|
|
||||||
|
### Tone Squelch Sensitivity
|
||||||
|
|
||||||
|
If tone squelch is unreliable:
|
||||||
|
|
||||||
|
```
|
||||||
|
TSL # Low sensitivity (default)
|
||||||
|
TSM # Medium sensitivity
|
||||||
|
TSH # High sensitivity
|
||||||
|
```
|
||||||
|
|
||||||
|
## Transmitting
|
||||||
|
|
||||||
|
### Manual PTT
|
||||||
|
|
||||||
|
Ground the PTT pad or press the button on a speaker-mic. The TX LED illuminates during transmission.
|
||||||
|
|
||||||
|
### Software Control
|
||||||
|
|
||||||
|
Transmit via serial command:
|
||||||
|
|
||||||
|
```
|
||||||
|
TX1 # Transmit with 1 minute timeout
|
||||||
|
TX2 # Transmit with 2 minute timeout
|
||||||
|
TX5 # Transmit with 5 minute timeout
|
||||||
|
TX0 # Stop transmitting immediately
|
||||||
|
```
|
||||||
|
|
||||||
|
:::caution[TX0 Override]
|
||||||
|
`TX0` will stop transmission even if the hardware PTT line is still held low.
|
||||||
|
:::
|
||||||
|
|
||||||
|
### Timeout Timer
|
||||||
|
|
||||||
|
Prevent excessive transmissions with the timeout timer:
|
||||||
|
|
||||||
|
```
|
||||||
|
TO120 # 120 second (2 minute) timeout
|
||||||
|
TO300 # 5 minute timeout
|
||||||
|
TO000 # Disable timeout
|
||||||
|
TO? # Query current setting
|
||||||
|
```
|
||||||
|
|
||||||
|
When timeout occurs, the RS-UV3A sends a configurable CW message and unkeys:
|
||||||
|
|
||||||
|
```
|
||||||
|
TG TO # Set timeout message to "TO"
|
||||||
|
TGTIME # Set timeout message to "TIME"
|
||||||
|
```
|
||||||
|
|
||||||
|
## TX Power
|
||||||
|
|
||||||
|
The RS-UV3A has two power levels:
|
||||||
|
|
||||||
|
```
|
||||||
|
PW1 # High power (~200 mW, 23 dBm)
|
||||||
|
PW0 # Low power (~10 mW, 10 dBm)
|
||||||
|
PW? # Query current setting
|
||||||
|
```
|
||||||
|
|
||||||
|
## VOX Operation
|
||||||
|
|
||||||
|
The RS-UV3A includes voice-operated transmit (VOX):
|
||||||
|
|
||||||
|
```
|
||||||
|
VX1 # Enable VOX
|
||||||
|
VX0 # Disable VOX (default)
|
||||||
|
VL0 # High sensitivity
|
||||||
|
VL1 # Medium sensitivity (default)
|
||||||
|
VL2 # Low sensitivity
|
||||||
|
```
|
||||||
|
|
||||||
|
:::warning[Don't use VOX with speaker-mic]
|
||||||
|
VOX will key the transmitter when it hears audio from the speaker. Only use VOX with headphones or when the speaker is isolated from the microphone.
|
||||||
|
:::
|
||||||
|
|
||||||
|
## Pre/De-emphasis
|
||||||
|
|
||||||
|
For standard FM voice, keep pre-emphasis and de-emphasis enabled:
|
||||||
|
|
||||||
|
```
|
||||||
|
DP1 # Enabled (default)
|
||||||
|
DP0 # Disabled (for some data modes)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Signal Monitoring
|
||||||
|
|
||||||
|
Read current signal conditions:
|
||||||
|
|
||||||
|
```
|
||||||
|
SS # Signal strength in dBm
|
||||||
|
SN # Noise level (lower = cleaner signal)
|
||||||
|
SO # Squelch state (0 = closed, 1 = open)
|
||||||
|
```
|
||||||
|
|
||||||
|

## DP – Pre/De-emphasis
|
||||||
|
|
||||||
|
Enables or disables TX pre-emphasis and RX de-emphasis.
|
||||||
|
|
||||||
|
### Syntax
|
||||||
|
|
||||||
|
```
|
||||||
|
DPn
|
||||||
|
DP?
|
||||||
|
```
|
||||||
|
|
||||||
|
### Parameters
|
||||||
|
|
||||||
|
| Value | Description |
|
||||||
|
|-------|-------------|
|
||||||
|
| 0 | Pre/de-emphasis OFF (flat response) |
|
||||||
|
| 1 | Pre/de-emphasis ON (standard FM) |
|
||||||
|
|
||||||
|
### Default
|
||||||
|
|
||||||
|
1 (ON)
|
||||||
|
|
||||||
|
### Examples
|
||||||
|
|
||||||
|
```
|
||||||
|
DP1 # Standard FM voice mode
|
||||||
|
DP0 # Flat response for data
|
||||||
|
DP? # Query current setting
|
||||||
|
```
|
||||||
|
|
||||||
|
### Notes
|
||||||
|
|
||||||
|
- Standard FM uses pre-emphasis on TX and de-emphasis on RX
|
||||||
|
- Pre-emphasis boosts high frequencies on transmit
|
||||||
|
- De-emphasis cuts high frequencies on receive
|
||||||
|
- For packet radio, `DP0` may provide flatter audio response
|
||||||
|
- 9600 baud packet typically requires `DP0`

|
||||||
|
|
||||||
|
```
|
||||||
|
FS146520 # Simplex on 146.520 MHz
|
||||||
|
FD146940 # RX 146.940, TX 146.340 (-600 kHz)
|
||||||
|
FU147060 # RX 147.060, TX 147.660 (+600 kHz)
|
||||||
|
FR223500 # Set RX only to 223.500 MHz

|
||||||
|
TX: 146520
|
||||||
|
```
|
||||||
|
|
||||||
|
### Notes
|
||||||
|
|
||||||
|
- Frequency range: 136-174 MHz, 200-260 MHz, 400-520 MHz
|
||||||
|
- The RS-UV3A is designed to transmit only on amateur frequencies
|
||||||
|
- TX outside amateur bands may have reduced power due to filtering
|
||||||
|
- Firmware 2.4+ supports 0.5 kHz steps by adding `5` to frequency
|
||||||
|
|
||||||
|
### 0.5 kHz Steps (Firmware 2.4+)
|
||||||
|
|
||||||
|
For frequencies like 146.5225 MHz:
|
||||||
|
|
||||||
|
```
|
||||||
|
FS1465225 # 146.5225 MHz (note: 7 digits)
|
||||||
|
```
|
||||||
|
|
||||||

||||||
|
### Notes
|
||||||
|
|
||||||
|
- Measurement takes approximately 100 ms
|
||||||
|
- Returns to original frequency after measurement
|
||||||
|
- Useful for channel activity monitoring
|
||||||
|
- Can be used to build a basic spectrum display with a controller
|
||||||
|
- Signal level is raw RSSI, not calibrated to a specific standard
|
||||||
|
|
||||||
|
### Applications
|
||||||
|
|
||||||
|
**Channel scanning:**
|
||||||
|
```
|
||||||
|
FM144390 # Check APRS frequency
|
||||||
|
FM146520 # Check calling frequency
|
||||||
|
FM146940 # Check local repeater
|
||||||
|
```
|
||||||
|
|
||||||
|
**Signal survey:**
|
||||||
|
Use with an Arduino or other controller to scan frequencies and log signal levels for propagation studies or interference hunting.

This page provides a quick reference for all 66 RS-UV3A serial commands. Click on a command to see detailed documentation.
|
||||||
|
|
||||||
|
## Command Syntax
|
||||||
|
|
||||||
|
- Commands are **not case sensitive** (`fs` = `FS`)
|
||||||
|
- Commands end with **carriage return** (CR, ASCII 13)
|
||||||
|
- Numeric parameters require **all digits** (e.g., `FS146520` not `FS14652`)
|
||||||
|
- Query current value with **`?`** suffix (e.g., `F?`, `SQ?`)
|
||||||
|
- Default baud rate is **19200**
|
||||||
|
|
||||||
|
:::danger[Serial Port Warning]
|
||||||
|
The DB-9 connector uses **TTL levels (3.3V/5V)**, NOT RS-232 voltages. Do not connect to a standard RS-232 port.

||||||
|
| 2 | Encode + decode (TX tone + tone squelch) |
|
||||||
|
| 3 | DCS mode (if supported by firmware) |
|
||||||
|
|
||||||
|
### Default
|
||||||
|
|
||||||

0 (Off)
|
||||||
|
|
||||||
|
### Examples
|
||||||
|
|
||||||
|
```
|
||||||
|
TM0 # No CTCSS
|
||||||
|
TM1 # Encode tone on TX only
|
||||||
|
TM2 # Encode tone + require tone to open squelch
|
||||||
|
TM? # Query current mode
|
||||||
|
```
|
||||||
|
|
||||||
|
### Use Cases
|
||||||
|
|
||||||
|
| Mode | Use Case |
|
||||||
|
|------|----------|
|
||||||
|
| `TM0` | Open repeaters, simplex |
|
||||||
|
| `TM1` | Repeater requires PL, hear all traffic |
|
||||||
|
| `TM2` | Only hear stations with your PL tone |
|
||||||
|
|
||||||
|
### Notes
|
||||||
|
|
||||||
|
- `TM1` sends tone but doesn't require it to receive
|
||||||
|
- `TM2` provides selective calling capability
|
||||||
|
- Tone frequency set by `TF` command
|
||||||
|

## TS – Tone Sensitivity
|
||||||
|
|
||||||
|
Sets CTCSS decoder sensitivity for tone squelch.
|
||||||
|
|
||||||
|
### Syntax
|
||||||
|
|
||||||
|
```
|
||||||
|
TSx
|
||||||
|
TS?
|
||||||
|
```
|
||||||
|
|
||||||
|
### Parameters
|
||||||
|
|
||||||
|
| Value | Description |
|
||||||
|
|-------|-------------|
|
||||||
|
| L | Low sensitivity |
|
||||||
|
| M | Medium sensitivity |
|
||||||
|
| H | High sensitivity |
|
||||||
|
|
||||||
|
### Default
|
||||||
|
|
||||||
|
L (Low)
|
||||||
|
|
||||||
|
### Examples
|
||||||
|
|
||||||
|
```
|
||||||
|
TSL # Low sensitivity (default)
|
||||||
|
TSM # Medium sensitivity
|
||||||
|
TSH # High sensitivity
|
||||||
|
TS? # Query current setting
|
||||||
|
```
|
||||||
|
|
||||||
|
### Notes
|
||||||
|
|
||||||
|
- Higher sensitivity = detects weaker tones
|
||||||
|
- May cause false triggers on noise with `TSH`
|
||||||
|
- Use `TSM` or `TSH` if tone squelch is unreliable
|
||||||
|
- Only affects RX tone detection, not TX encoding
|
||||||
|
|
||||||
|

|
## Firmware Compatibility
|
||||||
|
|
||||||
|
All revisions use the same firmware, but some features are revision-specific:
|
||||||
|
|
||||||
|
| Feature | Rev A | Rev D | Rev C | Rev B |
|
||||||
|
|---------|:-----:|:-----:|:-----:|:-----:|
|
||||||
|
| `LD` (ST LED) | ✓ | ✓ | ✓ | — |
|
||||||
|
| `BS` (Battery Status) | Legacy | ✓ | ✓ | ✓ |
|
||||||
|
| `VT` (Voltage) | ✓* | ✓ | ✓ | ✓ |
|
||||||
|
|
||||||
|
*Rev A returns internal 8.5V rail voltage
|
||||||
|
|
||||||
|
## Physical Compatibility
|
||||||
|
|
||||||
|
All revisions share the same:
|
||||||
|
- Board dimensions (120 × 75 mm)
|
||||||
|
- Mounting hole positions
|
||||||
|
- SMA antenna position
|
||||||
|
- Arduino header pinout
|
||||||
|
|
||||||
|
This ensures enclosures and accessories are compatible across revisions.
|
||||||
|
|
||||||
|
## Upgrading from Older Revisions
|
||||||
|
|
||||||
|
### Rev C/D to Rev A
|
||||||
|
|
||||||
|
If upgrading from Rev C/D:
|
||||||
|
|
||||||
|
1. **Battery:** Rev A has no charging—use external power management
|
||||||
|
2. **Serial:** Rev A has on-board USB—FTDI cable not required
|
||||||
|
3. **Voltage:** Rev A accepts lower voltages (3.5V vs 9V)
|
||||||
|
4. **Settings:** Use `FD1` to reset to defaults after firmware update
|
||||||
|
|
||||||
|
### Power Considerations
|
||||||
|
|
||||||
|
| Revision | Minimum Voltage | USB Power |
|
||||||
|
|----------|-----------------|-----------|
|
||||||
|
| Rev A | 3.5V | Yes |
|
||||||
|
| Rev C/D | 9V | No (FTDI for serial only) |
|
||||||
|
|
||||||
|
## RS-UVPA Compatibility
|
||||||
|
|
||||||
|
The RS-UVPA power amplifier is compatible with:
|
||||||
|
- RS-UV3A Rev A
|
||||||
|
- RS-UV3 Rev D
|
||||||
|
- RS-UV3 Rev C
|
||||||
|
|
||||||
|
Rev B may require additional modifications—contact HobbyPCB.
|
||||||
|
|
||||||
|
### Installation Differences
|
||||||
|
|
||||||
|
**Rev A Installation:**
|
||||||
|
1. Remove solder from SJ1
|
||||||
|
2. Add AMP, PW, and PA headers
|
||||||
|
3. Remove VIN connector (interferes with amp)
|
||||||
|
4. Mate boards
|
||||||
|
|
||||||
|
**Rev C/D Installation:**
|
||||||
|
1. Remove solder from SJ1
|
||||||
|
2. Add required headers
|
||||||
|
3. Remove VIN connector
|
||||||
|
4. Mate boards
|
||||||
|
|
||||||
|
## Identifying Your Revision
|
||||||
|
|
||||||
|
Check the silkscreen on the PCB near the edge for the revision letter:
|
||||||
|
- "RS-UV3A Rev A"
|
||||||
|
- "RS-UV3 Rev D"
|
||||||
|
- "RS-UV3 Rev C"
|
||||||
|
|
||||||
|
Or query firmware:
|
||||||
|
```
|
||||||
|
FW
|
||||||
|
```
|
||||||
|
|
||||||
|
Firmware versions don't indicate hardware revision, but feature behavior may hint at the hardware (e.g., `BS` command behavior).
|
||||||
|
|
||||||
|
