[amsat-bb] Are we ever going to learn?

If you could copy the cq could you copy the call?

At 432 MHz the AO-7 uplink is actually in the weak signal part of the band.
It is very possible a weak signal station unknowingly did this...

A friendly email to the station may help!

AO-7 was sounding pretty good. Very strong signals over North America
around 2200Z, I was having a nice QSO with KC4LE, reducing my power to
1 watt when my signal started to warble a bit, until someone started
CQing in CW with such a strong signal that the whole passband was
pulsing up and down. Eventually the Mode B transponder shut off under
the strain.

Using excessive power on a linear transponder is a violation of two
sections of Part 97: using minimum power necessary to complete the
communcations and causing harmful interference to other stations. We
need an ARRL OO to listen to a few passes and send some OO notices!
