Today, Monday, I followed three passes of AO-51. Downlink seems to be perfect with antenna mounted pre-amp activated and LHC polarisation: Four to five times "PB: Empty." followed by "Open ABCD: B: 96373368" No sign of any successful uplink. I tried directory requests with different output levels and different circular polarisations on 145.86 MHz, to no avail.

Anybody else successful ?
