Oh, I forgot to mention HO-68 has a great CW beacon at 435.790. Listening to
it right now. It's also in a great 1200km orbit, so long passes and slower

A few suggestions based on my experience.
Don't use HRD for sats, especially to tune. SatPC32 is far superior for
satellite tracking, and while some stubbornly stick to HRD, those that move
to SatPC32 rarely go back. You don't have to register SatPC32 to begin using
Forget auto tuning to start with. Run some pass predictions and double check
them with the AMSAT page. and listen, tuning around a bit. Point the
antennas at the TCA heading (time of closest approach) and listen there for
the entire pass to begin with. This will compensate for any clock, kep, or
frequency inaccuracies. During the week and when illuminated, AO-73 has a
booming BPSK beacon. FO-29 is weaker, but always there. Start with those two
and see if these steps lead to any success.
