In addition – if I use a direwolf.conf for the left port @ 1200 baud and PTT set to GPIO 12, exactly the same as below. PPT is proper timing with no sound. Grrr….

Making some progress – but not there yet with Direwolf.
To troubleshoot the DRAWS board over lunch, compiled fldigi using the UDRCII destructions to see if I could get fldigi to start up properly without a crash after the configuration step. It starts up but lacks a waterfall. I did not stick around to see errors unfortunately. The good news is that it hears and transmits using the DRAWS board, so I have to assume there is nothing wrong with the board right port (port 0). The mixer adjusted the audio levels to those recommended for the IC-7000. I can’t see the waterfall so I can’t zero in on a signal, but decodes “noise” in PSK31 when close to a signal and decoded some CW (but typically in my experience with fldigi, poor copy). Now will assume the sound circuitry is OK.
As I was playing with fldigi, I noticed in those instructions that the right channel PTT was set for GPIO23, not GPIO12? On a hunch, I swapped the GPIO assignments for PTT and de-configured left port as shown below. The rig now keys up for an appropriate length of time for digipeating the beacon of my HT @ 1200 baud… but is still not transmitting audio – not even noise.
SO why this apparent problem with PTT assignment? Still trying to understand the audio issue too.
