[amsat-bb] Modulation levels on AO-85

My experience with LOTW and SAT QSO's is the frequency does matter. I
have had to fool my logging program to upload the uplink frequency to
get a match on a rare occasion. N5JB's guide to LOTW and satellite
QSO's says 7 items must match to get a satellite verification in LOTW.
Only 5 items need to match for a non-satellite QSO.
