Luc -- I recorded the transponder downlink band on my funcube dongle while testing the transponder, and had a chance to listen to the result several times. It doesn't seem that the telem or FM signals are measurably less powerful at the times when a bunch of us got through on the transponder. I can make the HDSDR data file available to whoever would like to look over it. 73, Bruce VE9QRP -- http://ve9qrp.blogspot.com _______________________________________________ Sent via [email protected].
