Working now... Nice contact with W9AE in Oregon. Low pass, so not super strong, but now I can start optimizing things... At the end of the contact, Rx was at 145.960, Tx was 435.155 (both dial readings on my FT-736r).

It was also my first AO-73 contact. I had set up SatPC32 Doppler tuning with the frequencies published on the AMSAT-UK web site. I only needed to adjust the TX Offset by +1200 Hz.

The frequency probably varies that much from day to day due to temperature changes.
