Ok, I'm new at this so please forgive me if these should be obvious... The 736R manual explains how to set up full duplex so that the tx freq tunes with (opposite direction) of the rx frequency, as you adjust the rx freq for doppler shift. So, here are my questions.

1. Where do initially set my tx freq? On the UL freq listed for the sat?

2. Since the satellite is normally in full use before it gets within range for me to hear it, how would I listen for my own signal without interfering with others using the bird? Will tuning in the received signals work instead?

Thanks for your time and consideration,
Mark, KØXXX

The listed freqs are when the sat is directly overhead.  Due to Doppler, the freq will be lower as the bird approaches you and then go higher as it goes away from you.  Takes some practice.

You can't.  Just set the offset correctly and fire away.

Yes
