I also noticed a lot of "warbling" on the AO-7 stations I heard. I'm assuming this is the "FM'ing" I've read about. I cranked my power down to about 10 Watts on the AO-7 passes I tried to work, and my downlink sounded "OK", but some guys had a very 'watery' sound. I also noticed a couple of sats where the downlink seemed to "drop out" after I heard some very LOUD stations on them. I don't think it was receive blockage causing me to lose the signal, but it was something I never heard before. Jim

I called CQ multiple times on AO-7 in CW last night between 145.940 and 145.944 (downlink), and NOBODY was tuning down that far. I found that very disappointing, as I did the close proximity of all the stations on FO-29 and VO-52. I believe a lot of us could have made a lot more contacts on the linear satellites if we'd just used the passband.
