Hello Isaiah,

Thank you for closing that Direwolf Github issue and coming here (or the Direwolf list).? Few things here:

?? 1. Don't use a relay for PTT as you will dramatically impact your packet performance.? Just use a simple transistor circuit like this one: .? There are literally 100s of examples out there on the web:? "PTT"+circuit .? Just make you use one that uses a transistor for PTT and has capacitors to isolate any microphone DC bias voltage.

?? 2. How else have you connected your radio to the soundcard?? It's worth mentioning that the above circuit is missing a capacitor on the "Speaker out" line.

Good afternoon,

I’m have Direwolf set up on my raspberry pi and it will not tx audio. I have the PTT configured with a relay and that will not fire either when I see the magenta text appear. It IS receiving and decoding signals, and is indicating so on the light I configured so I know GPIO is functional. Thoughts?

David,

Thanks for the response.

I have the input and output wired directly to each other with a Baofeng as the transceiver. I simply have two RCA plugs that go to a dismantled baofeng handheld microphone cable. The PTT works by applying the PTT line to ground, that's what's connected to the relay (I'll upgrade this). I certainly can improve the connection as you've suggested but it isn't attempting to output at all nor trying to trigger the GPIO. That's what's strange.

I have?an ICOM IC-7100 with Direwolf connected and it works flawlessly with reception, decoding, and transmission - but this won't attempt to transmit.

If it's not even attempting to trigger the gpio, there are a couple possibilities....

What does 'systemctl status direwolf' show you?? ?If it's not running as root, it may not have access to the gpio pins

So I tried moving it to GPIO 17, no change. I see the magenta text, but no transmission. Yet it receives audio perfectly fine and the light turns on for DCD.

The PTT works by applying the PTT line to ground, that's what's connected to the relay (I'll upgrade this). I certainly can improve the connection as you've suggested but it isn't attempting to output at all nor trying to trigger the GPIO. That's what's strange.

I have?an ICOM IC-7100 with Direwolf connected and it works flawlessly with reception, decoding, and transmission - but this won't attempt to transmit.

Good afternoon,

I’m have Direwolf set up on my raspberry pi and it will not tx audio. I have the PTT configured with a relay and that will not fire either when I see the magenta text appear. It IS receiving and decoding signals, and is indicating so on the light I configured so I know GPIO is functional. Thoughts?

Thanks for the response.

I have the input and output wired directly to each other with a Baofeng as the transceiver. I simply have two RCA plugs that go to a dismantled baofeng handheld microphone cable. The PTT works by applying the PTT line to ground, that's what's connected to the relay (I'll upgrade this). I certainly can improve the connection as you've suggested but it isn't attempting to output at all nor trying to trigger the GPIO. That's what's strange.

I would recommend to move the DCD LED over to the GPIO pin being used for PTT and see if the LED lights up when you send a beacon or other packet transmission.? If that doesn't light up, there is something wrong.? Also consider running Direwolf with debugging turned on:

Hey Isaiah,

Please be specific, WHAT worked?? You put an LED on the PTT GPIO pin and now it lights up when Direwolf wants to send something?? If that's true, your radio's PTT shouldn't be connected or did you connect both at the same time?
If it's the later, it's critical that you get the antenna away from the overall Raspberry Pi system.? For now, lower the power to the lowest level, etc.? Btw.. a diode won't help here.. you'll need to figure out how to keep the RF out of the system using shielding, ferrite chokes, etc.
