Here is my very first acquisition of Tianwen-1 on open waveguide pointing about 220deg. As this point the signal frequency was unknown so it had to be found by brute force. Doppler shows spacecraft approaching me. Launched 23 July 2020, 04
15 UTC and I detected it at 23 July 2020, 06:01:04 UTC not bad ;-)

Waterfall shows AOS from low easterly horizon, hence the increasing signal. You can see thermal noise drop off as the green stuff leaves the dish beamwidth. The markers are the top 4 signals within the bandwidth.
