I've tried listening to a few passes (as high as 70 degrees) the last 2
days and heard nothing but silence. I must be doing something wrong.
Can the group confirm I am doing this right for the current cross band
My Xmit is 145.99 tone 67 hz
My RX is 437.8
My radios, antennas, preamps, and such are fine as I can still work
SO-50, AO-51, and FO-29. What gives?

Somebody posted those frequencies a couple days ago, but it seems
"backwards" to me. I thought ISS downlinks were ALWAYS on 2m.
I keep missing the ISS passes the last couple days, but I've loaded the
above frequencies and the reverse into Doppler.SQF on SatPC32, so I can
hopefully confirm which is the correct uplink/downlink for the crossband
The last time I worked the crossband repeater the downlink was
definitely on 2m, but that was probably using the "standard" crossband
repeater pair of 437.8 MHz up and 145.8 MHz down.
When you do finally hear the crossband repeater, speak softly or turn
the microphone gain way down. The crossband repeater's audio is easily
overloaded even when you transmit in FM-narrow mode (3 kHz deviation).
