[amsat-bb] XW2D satellite problem?

My observations have been the same.  Looking at the entire downlink passband 
on an SDR waterfall, I would see others at their spots on the transponder 
while I would be working through some other unused frequency.

We would all be good for a couple of seconds and then all drop to zero 
downlink at the same time.  The effect was the same whether transmitting SSB 
or CW.

The CW beacon is sending an intermittent solid tone lasting 2-3 seconds. 
The transponder is active during the same time the
tone is present.

Or could it be a problem on the ground somewhere in the footprint
de-sensing the satellite receiver?

I was on XW2D at1401 utc pass and experienced extreme intermittent signals
on the downlink ! Every few seconds I could hear myself , then would be
cut off  in mid sentence. K9VSW was also on but had the same problem. I
would hear his signal , then he would be cut off as well. Signal when
present was strong but there is a definite problem in the satellite  JACK
