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 
repeater?

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 
repeater.

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).
