I've heard a CW telemetry signal on 145.96 (AO-91 downlink frequency) 5-10 min. before the FM pass.  It's a bit hard to copy CW on a FM receiver but I've heard it 3 times in the last 2 days.  Seems to fade out prior to the AO-91 pass.  I expect it is an analog bird but so far I haven't figured out which.  Any guesses?Rusty, WA8ZIDSent from my Verizon, Samsung Galaxy smartphone
