Hi Bob, W7LRD

Since OSCAR-7 mode B and FO-29 mode-J have both inverting transponders using
SSB it happens that to be received as usually in USB over the FO-29 downlink
we must transmit as well USB into the OSCAR-7 uplink.

Since the noise translated by OSCAR-7 mode-B is very high probably a try on
CW will be convenient.

As Rick WA4NVM pointed out with OSCAR-7 mode-B and OSCAR-8 mode-J
it was a common practice.
