A couple days ago work G0ABI via AO-91 based on a sched we had made. Suddenly the elevation in my rotor did not work! So I moved it by hand, called and called...I did not hear myself. Later Peter sent me a recording--he had heard me just fine so my Rx was screwed up
Today, I found the rotor problem (a cable). I had hoped it would be the same problem with the Rx (like a hungry mouse) but no, apparently not. So I tried 91 again today. Wait, why is the downlink band so quiet? First, something had happened to my database in MacDoppler and it was all hosed. It had the AO-91 as a V/u satellite and the wrong freq anyway. Fixed that in time. Still very quiet on the band. Took my HT to probe around a bit. Some strong carrier on 145.965. I went outside and suddenly heard a voice. Aha! Someone using the satellite band! Oh, wait, that is AO-91 booming in on my HT with rubber ducky at about 5 degrees above the horizon! That was actually pretty cool! (I was probably hearing contacts with SparkFest!)
Still trying to find the source of the 145.965 (besides AO-91 of course). It is clearly inside my house--I even know which breaker. But so far not the obvious things (power supply, network switch, computer, UPS, etc). I'll keep looking.
But it just goes to show that when a bunch of things happen at once, it is not ALWAYS due to the same root cause.
