Direwolf for CAS-4 telemetry decoding
A hint for people who want to use Direwolf instead of UZ7HO's soundmodem.
I finally worked out why I wasn't having success with decoding telemetry from CAS-4AB: for decoding 4800 baud signals you need the K9NG/G3RUH baseband and that needs a special setting in the Direwolf config file, namely in the modem entry. Normally the modem entry looks like this....
MODEM 4800
Change it to the following and it works....
MODEM 4800 0:0
This info can be found in section 9.2.2 "Radio channel -Modem configuration , general form" of the Direwolf user guide.
You can find the complete config file and screenshots of the decoding process on my website: BX2ABT.com
Next step is to decode telemetry from the XiWang sats. They are using 9600 baud and from what I understand the GOMX-1 baseband. Not sure what the difference is with G3RUH, so any hint on reading material to start grokking this stuff is apperiated.
