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.
