To start, The Digirig was working perfectly. I purchased the unit (digirig mobile) approximately a year ago (I think) but didn’t use It at all until two days ago, when I got my amateur license. It was working great, I was able to send an email with winlink using PAT (open source winlink client) and direwolf on my linux box, and I was able to connect to bulletin board nodes on ax25 using direwolf as the modem and paracon as the UI. So now onto the problem ☹ which is unfortunate. The digirig still shows up as a sound device, can still key the PTT. I wasn’t using it to TX audio to begin with, but it can do that as well (I am using a QYT kt-8900d. (audio into the radio is a btech aprs cable on the splitter accessory from btech that has a rj45 port, plug, and k1 port on the front. I was recieving audio from the radio to my computer using 3 lead trrs cables on the back port (data + audio in + audio out) and also using that for the ptt (with the digirig). Kinda a bootleg setup but I didn’t have any 4 lead trrs cables available so I made do with what I had lying around. I also tested it with my baofeng uv5r and non-homebrew stock digirig cables. Which was working fine before as well but wasn’t anymore either. So what I need to know, is this a hardware issue with the digirig? Both radios worked before with this digirig mobile unit and now both do not. I also tested both radios off of two different linux PCs as well just to be sure it wasn’t a PC hardware/pipewire-pulse software issue. Any help is greatly appreciated. Thank you! TL:dr When the radio recieves audio the mic interface of the digirig goes quiet and does not decode packets. ---

Not an expert, but with any troubleshooting, the aim is to first reduce variables and reproduce the problem. You have tried the stock cables with a baofeng and you have tried with a different computer. The next step is to try with a different digirig. The results of that will determine what the issue is. ---

Sorry, I feel really bad for taking so long to follow up. I know longer think it is a digirig issue but wrather a direwolf/pulseaudio issue. Sorry. I will be purchasing another digirig soon however and hopefully I can get it worked out so I won’t have to switch to windblows. (on at least one of my old laptops that is) direwolf just won’t operate ax25 connections… ☹ ---

I’m working on a pure python based packet radio protocol. It won’t need direwolf or fldigi or any of the others. Just python. I’ll leave a link when I make the first version public. Probably a few months out still.
