How do I play ARRL segment over Anytone 578UV

,
1

I’m a net operator and I use the Anytone 578UV on a UHF repeater. As part of my net operation I need to cut to a computer audio segment from ARRL Newsline. I purchased the digrig interface and cable and interconnected with a RJ45 switch between mic and computer. What software should I download to be able to simply Key the radio from the computer the digrig does show up working in the device manager. Appreciate any help

To continue our email conversation here so others can benefit from the findings:

Digirig is a standard sound card as far as your computer is concerned. You can play audio from any app that can play audio as long as you route it into Digirig’s playback device.
You can assign default playback devices to different apps in the system settings. Here are some of the suggestions on how this can be done in windows:

Next is the question about keying up the radio for the playback:

With the digital modes the PTT is typically handled by the software generating the audio payload. In this case I’m not sure if there is an existing app that will key up the radio (PTT by RTS in case of Digirig Mobile) while the voice audio is playing. Below see a custom Python code that will do that - didn’t have a chance to test it so it will be up to you or somebody involved in the project. The alternative option is to use radio’s PTT by VOX if available.

Install the dependencies with:

pip install sounddevice soundfile pyserial

Usage examples:

bash

# List audio devices to find the right ID
python play_wav_with_rts.py --list-devices

# List available COM ports
python play_wav_with_rts.py --list-ports

# Play on default audio device, RTS on COM3
python play_wav_with_rts.py audio.wav --com COM3

# Play on a specific audio device (e.g. device 5)
python play_wav_with_rts.py audio.wav --com COM3 --device 5

# Linux example
python play_wav_with_rts.py audio.wav --com /dev/ttyUSB0 --device 2

How the timing works:

  1. RTS goes HIGH

  2. Wait 0.5 s (leading pad)

  3. WAV playback starts and blocks until done

  4. Wait 0.5 s (trailing pad)

  5. RTS goes LOW

Ctrl+C during playback will immediately drop RTS low and stop audio.

The team there especially Denis has been great helping me work through this issue. Drivers installed no issues. Installed WSJT -X software. Configured per the troubleshooting and still no transmit on the Anytone 578 UV. If I remove the serial cable the radio does not transmit when touching shield a ring which points to radio anyone have this working with some configuration checks ? Would really be appreciated

Anytone AT-D578 is a special case with their unfortunate decision to reuse the mic wiring for different functions. For that reason, the cable variant you connect must match the PTT method you select in the transceiver settings and in software. For hardware PTT the cable variant should be one without serial CAT control and the mic type should be set to “Volt-Det” in transceiver settings. More details are in the product page for the cable:

Thanks Denis I will try this

So as a start I did buy the one with CAT control so Denis are you stating I should purchase the one without CAT control?

You can key up the radio with the cable you purchased as long as radio is set to the CAT-capable mic (default), and you use software configured to key up your Anytone via the CAT command (not PTT by RTS).

Ok will try that thank you
