I have an FTM-400 that I have connected my new Digirig mobile to. If I switch to the national weather service(NWS) frequency I can hear the audio from the transmission on my PC which is great. However, if I switch to a repeater frequency I get static like the squelch level is turned off unless someone is keying up the repeater. Is there a third party app that I can pipe the audio through to act as squelch control? Ideally I would really love to push audio to/from the PC to the FTM-400. The main driving factor of this is that I am wanting to use my desktop PC (using VB-Audio VoiceMeter) as a mixer for listening to the FTM-400 and FTDX10 using the same headphones. Especially helpful when late at night and the wife/kids are asleep upstairs. ---

Ham-audio-bridge is a project to do what you are describing: > [@Use DigiRig v1.9 for USB microphone interface to radio mic audio input](https://forum.digirig.net/t/use-digirig-v1-9-for-usb-microphone-interface-to-radio-mic-audio-input/2780/6): > > @ve7tzb I think [this project, ham-audio-bridge on GitHub,](https://github.com/jrobertfisher/ham-audio-bridge/wiki) has the goals you set out in your original post. I have not tried out this software. Please post any feedback here because the [author posts on this forum](https://forum.digirig.net/t/ham-audio-bridge-v1-0-testing/1667) too. 73 Constrainted Good luck. 73 Constrainted ---

Your other option, would be to not use the data jack, where the audio is unsquelched, and instead make a cable that ports the speaker audio in, where the squelch does work. A challenge you’ll run into with ham-audio-bridge, is that it doesn’t squelch, so you’re right back where you started. And just to be clear, unsquelched audio has a higher “level” than actual voice, so you can’t simply set a level (on FM). When using LSB/USB, you actually can set a level to “break squelch”, however, you can miss a LOT of voice traffic in doing so, just to avoid random noise spikes. You might also consider a plain simple physical mixer, where you can port the “speaker out” from each radio and mix it. I do this with a MAckie ProFX (FT857, FTM100DR, CS800, TYT9000D 220, FT991A, XPR5550e, and an IC7300.) I have a headset to listen to if I don’t want “room audio” and I can easily vary the level of each radio on the mixer. Matt AL0R ---

That is a good idea. I was most likely trying to do things the difficult way. I will have to look into an external physical mixer. ---

I am a feed provider on broadcastify and I use an audio gate program called Noisegator. It cleans up my scanner audio nicely.
