[amsat-bb] Modulation levels on AO-85

I've had a few match even though I accidentally uploaded a "20m" SAT qso because my logger autofilled the band field incorrectly lol.

In the few cases I couldn't get a match because of some unknown hiccup in LOTW, I have just changed the qso time by a minute or two (so lotw recognized it as a different qso record), reuploaded and got a match. 

Most of the satellite lotw info I've read online has mentioned several adif fields that don't seem to make a difference. In my experience, only the callsign,gh SAT mode, satellite name, time, and mode (FM, SSB etc) have to match. Ymmv.

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.
