XW-2Dwas doing the exact same thing yesterday as well on one pass.  During a later pass it was working normally.  

Hope it helps

Dear Folks:

I just got off from a pass of XW-2D.  The pass started at around 23:48UTC here in my grid square of DM-79.  It was a pretty good pass over my QTH with the highest point being at an elevation of about 50 degrees.

I observed that the satellite appeared to be operating intermittently, i.e., it would cut in and out.  I would transmit, and suddenly, my signal would appear on the downlink at about S6 or S7, and after a few syllables, it would cut out completely.  A couple of times, I could hear someone else coming in on the downlink but I could only hear a few syllables as well and then they would cut out much like me.  Occasionally, I would hear an intermittent buzzing noise.

I then turned my receive frequency to the beacon.  The beacon wasn't audible most of the time.  Every now and then, I'd hear what appeared to be a solitary dash, but nothing else on the beacon frequency.  I did vary my receive frequency to account for doppler and heard nothing else but that occasional solitary dash.

For the record, immediately before the pass, I had worked an RS-44 pass without difficulty or anomaly.  After the pass, I switched to some local repeaters and my equipment worked normally.  Thus, I don't think my setup was the reason why XW-2D appeared to be operating intermittently.

Anyone have any ideas what is going on?

Thanks and 73 de Bernie, KF0QS
