Pedro, For 9600B I connect PTT and TX data to the sub jack and receive audio to the Main Jack. This has worked fine for many satellites and several different TNC's.
For 1200b I use the aux jack. This works fine for both satellite and simplex. Bom Gia and 73 Tom K8TL _______________________________________________ Sent via AMSAT-BB@amsat.org.
