Hi Tim
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 the issue. 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.

Hey everyone,
For those of you who didn't hear the pass, the ability to reach AO-51 vaporized about 2/3 through this last orbit up North America from the south, thanks to a carrier or some kind of interference stronger than I have ever heard. Whatever captured the satellite's uplink wiped out every signal trying to reach the satellite, based on what I heard from EM84.
I would direct this message to the control team and not post it to the BB if I believed for one second that what resulted in complete jamming of the satellite was not intentional and malicious.
I believe that it was.
