Your post reminded me of a time long ago.
I understand FM and Discriminator capture versus side band.
It was on AO-13 with a group chatting when all of a sudden there was a
very strong signal that
done the same thing to a linear transponder as a strong CW on freq would
do to FM.
As soon as the strong signal cease we attempted to get to the bottom of
It took 15 minutes or so when we found we had a Russian EME station on
our hands trying satellite for the first time.
After much attenuation we all had a nice chat.
I never heard that lad after that so I do not know what his summation of
his efforts were.
