AO-51 first L-SSB Up / S-FM down QSO

During the first week of August, AO-51 was in the L/S mode of operation.

Gould, WA4SXM, AO-51 Command station noted, "Due to a commnd station error AO-51 first came up in L (USB) uplink / S (FM) downlink mode for a day. Nevertheless Ib, OZ1MY determined the correct modulation scheme and had a QSO with Willi, OE6AG that afternoon. Probably a first for this mode."

AO-51 was then put in the FM mode for the uplink on its next pass over a command station. This demonstrated the versatile configuration of this satellite's radio equipment.
