I was on AO73 last night from southern Cal (DM13) at around 0555z, calling many CQs. I kept my downlink at about 145.955. My sigs peaked at S9 (no preamp), 5 el fixed at 30 deg. AO73 was very loud. I had no replies and heard no one but myself. It does take a little more work to keep up with the Doppler, but this is a great sat and I encourage you to take advantage when the transponder is turned on.
