Hi Philip,

I would recommend FO29 since it has a wide passband, a good downlink
signal, and is in mode J so the doppler shift is less on it. Very easy to
use satellite.  Call CQ near the center of the passband and I am sure you
will make some QSOs.  It is also a little higher up than some of the newer
satellites so it has a larger footprint of stations to work.

AO73 and the Chinese satellites have great downlink signals, but being in
Mode B, they doppler shift is much greater so you have to tune your uplink
signal much more often.

Remember that all of these linear satellites are inverting, so you want to
transmit on LSB so you can receive on USB.
