Just tried AO-51 L/SU. The S band signal is weaker than it has ever been. Or my old AO-40 (sobsob) S band rx setup is maybe failing. I was trying for "stereo" reception on uhf and S band. I did work KC9ELU just at his LOS. I had a fairly high elevation, anyone else notice this S band signal? Maybe I need a bigger dish. 73 Bob W7LRD Seattle
