Re: DRAWS downloadable Image? #draws #earlyadopters #setup #compassimage

The muting is great for packet but once we get fldigi working I’m going to need that RX audio to find signals.  If we can’t do it in software then I’ll have to savage one of these cables to inline a switch.

All in all, very happy with draws so far.  The only complaint I have is the power connector.  Hopefully once I get a case built I’ll be able to mount a proper one on it (5mm barrel or powerpole)

Hi Brian,


My testbed FT-817 does the same muting (but I like it). I am listening to transmitted audio with a TH D74A. DRAWS receive audio was basically fine after I ran the bash script for setting up the soundcard. The system has run flawlessly with Xastir all evening. DRAWS makes the 817 key up and make noise (with the 9600 port volume at 70), but I still need to adjust the DRAWS transmit audio level and change the timing parameter (hangtime, etc) so my other APRS gear will decode it… something for tomorrow.

I have Direwolf running now, but I couldn't deduce which of these three parameters was "input sensitivity" -- instead I changed the impedance from 10 kOhm to 20kOhm to get the levels right.  What is the recommended procedure?  

Is there any way to set these impedance values in software to get a Yaesu to stop muting audio?  I have no idea what pin causes a Yaesu to decide it is no longer going to output audio to the speaker, but I can't use it like this.  If I keep plugging and unplugging the mini-din I'm going to break the connector off the board.

Is there a way instead to enable the Raspberry Pi onboard audio and route the RX audio via mixer to it?
