New DigiRig - no RX audio

M0NFZ · April 22, 2024, 11:01am

Hello All,

Got My new DigiRig mobile last week and so far im impressed with the quality of the board, case, leads etc. however I’ve been struggling to use it all weekend. First tried it connected to a Pi and running direwolf. nothing was received. even with the volume on the radios adjusted. So thought to try and debug it I would plug it into the windows PC. This is where I notice no audio on the mic line.

I’ve followed the guides and videos etc and its setup exactly as it should but i get no audio at all on my windows 11 PC. If i enable ACG however I get the smallest amount of audio. not enough to even hear it though the loopback to the PC speakers.

to rule out anything else ive even gone as simple as running the baofeng in FM broadcast mode to output some from of audio, and then used audacity to record it. Again no audio at all unless AGC is enabled and even then its barely even moving the UV meter and not enough to even make out the audio on playback on pc speakers at full volume.

Ive also tried a second radio (anytone 878) and its the same on that too. pc gets no to very little audio.

Ive got the lead to connect it to a 891 as well, so I will try that lead to see if its an issue with the audio lead but im not sure it is as the leads look to be good quality. anyone else had these issues?

Im a little disappointed as otherwise this looks to be a great product, however this is confusing me.

So apperes to be more to this story now. I have tried to test TX as well now and also found that it triggers PTT but does not actually TX anything. Plugging headphones into the unit also gives no audio. so it seems this unit may be deaf and mute. maybe Im doing something wrong so open to suggestions.

Apologies for the difficulties with your Digirig setup.
Considering the amount of troubleshooting you went through I’m not expecting this to be something obvious. I’ll shoot you a pre-tested Digirig replacement unit and we’ll see if that fixes the issue with your audio.

M0NFZ · April 22, 2024, 10:17pm

Now that is what I call absolutely fantastic support and customer service. I am more then impressed honestly if everyone looked after everyone like this, the world would be a happier place

Honestly, I’m blown away. Thank you!!

I am curious to hear how this turns out.

How did this turn out? I am also not receiving any audio from my digirig with headphones plugged in. Tried different cables, headphones, and PC.

K0TX · May 16, 2024, 1:22am

Mark,
If there is a problem with your Digirig then I’ll handle the replacement.
Before we go ahead with that, let’s make sure it’s not some configuration issue.

When you test the audio output, do you see the bars next to Digirig’s playback audio device in the control panel?

Mark_G · May 16, 2024, 1:58am

Yes, the bars move up and down with the audio. Using WJTX this time for testing, I moved the “Power Slider” and was able to see the bars in the sound control panel move up and down with it. I have a pair of headphones plugged into the audio port on the Digirig and no sound is output.

K0TX · May 16, 2024, 2:12am

Ok, your test methodology checks out. Please PM me your order info including the shipping address and I’ll handle the exchange.

I’m having a similar problem to the fellas above. I tried to get digirig to work with svxlink following a few howtos on the web and could usually get Tx to work (Pi → other rigs on the freq) but no Rx (other rigs to the Pi). At one point I could get svxlink to respond to DTMF, but no actual voice to the Parrot server (for example).

I redid the whole Pi using SvxlinkBuilder and re-configuring the resulting svxlink to use serial/RTS for PTT. But now it transmits OK (Periodic station IDs are heard) but the Pi does not receive well … not even DTMF at present. When I send DTMF squelch opens and closes for a second, followed by PTT transmitting for a couple of seconds, but the sound does not come through.

Help anyone???

Peter,
There is a lot going on with your setup. Is there a chance you can try basic audio troubleshooting on a windows machine to rule out any software related issues?

KL7KUB · June 6, 2024, 11:59pm

I too have a similar issue. Open js8 and error in sound input message instantly pops up. Unable to receive any audio, no waterfall. When trying to transmit, same thing. I followed everything in the troubleshooting video and the part that I get to that doesn’t work is seeing if the digirigs bars go up in sounds (windows 10) when transmitting.

In other research, others are saying it could be interference. I’ve put tons of ferrite chokes and a toroid on the cables and still nothing.

I have a feeling it’s a setting in my tablet (Panasonic fz-m1) that isn’t recognizing or authorizing the digirig. But I sure am at a loss…

K0TX · June 7, 2024, 5:17pm

In the audio setting for the JS8Call try explicitly re-selecting Digirig’s audio components and then saving the form.

KL7KUB · June 7, 2024, 10:34pm

Thanks for getting back to me. I have a folder selected but there doesn’t appear to be anyway to ‘save’ anything.

Also sorry for the kinda crappy photos

Constrainted · June 7, 2024, 10:41pm

Very cool that you are running in a Japanese language environment! Digirig does not usually present its devices with Katakana characters, though.

Pressing OK will save the settings. Selecting Configurations → “Default” or “Some named Configuration” will let you manage configurations for different radios, or for testing, etc.

If you are on Windows, I have success getting screen captures by pressing Winkey-Shift-S at the same time and then selecting the area to be captured.

Good luck.

KL7KUB · June 7, 2024, 11:06pm

I’m using a Japanese version of the Panasonic fz-m1. Even with English selected, there’s some occasional Japanese. But I know that is definitely the digirig there

mlzinicola · April 15, 2025, 9:17pm

Ugh, I hate to add to the pile but I have been working on my DIGIRIG to work with Linux for days with DIREWOLF and cannot get it to RCV. It will transmit just fine and is recognized by alsamixer. I have viewed many videos on Youtube and still cannot get it to work even though I can hear the packet signals on the radio.

K0TX · April 15, 2025, 11:16pm

Michael, did you have a chance to try it on a PC? This will clarify if the issue is hardware related or in software configuration.

mlzinicola · April 16, 2025, 3:09pm

Yes and the problem appears to be with the configuration on the raspberry pi and Direwolf in Linux. I will definitely find out what the issue is and post it on the site.

Michael
