Re: New to DRAWS - what order to troubleshoot installation/setup? #draws #gps #ft817 #ft-817 #draws-manager


Hi Basil, I'm back at it.

So close. After pulling the #6 pin (and breaking the key off... oops), I can now see all sorts of APRS signals streaming in with:

tail -f /var/log/direwolf/direwolf.log

However, transmitting with:

./ -P udr0

shows up in this log, and the radio transmits, but still no reports on

My hand-held, with a rubber duck, get reported just fine. The SSIDs are indeed different, -7 on the hand held and, according to the log, -11 for the DRAWS-817.

By 'check deviation config' I assume you meant this?

pi@drawspi:~/bin $ ./

Any further suggestions?

I know it's holiday time, I am in no rush and really appreciate your help.

You have the current latest version of DRAWS hat.

systemctl status chronyd:
Instead of using systemctl try using this script for a more complete
look at gpsd/chrony status.

cd n7nix/gps

gpsmon now shows data! Yaaay!
I was able to start ax25 and see a direwolf PID.

tail -f /var/log/direwolf/direwolf.log gave:
Indicates you are not receiving any packets.
Assuming you tuned your radio to the APRS 2M frequency 144.390 you
should be seeing plenty of received packets.

Check squelch setting on radio and you may have a SQL/COS problem and
you will have to remove pin 6 from your mDin6 connector.

Read the first part from this link:

Using ./ -P udr0 I can get the radio to switch to transmit and
hear the signal on a hand-held (on 144.39), but no raw packet shows on am not too worried about that right now. Enough for one day.
Check deviation config, and distance to a working APRS gateway.

Also AX.25 tends to eat the first 2 transmitted packets after a
reset. It thinks they are TNC control packets. So always send 3 packets
after a power-on or ax25-restart.
