Re: Please check my settings for ISS

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).

You need to check the date of your keps. ISS needs very up-to-date keps due to the ability to vary its orbit when necessary.

The ISS repeater is indeed in "upside down" mode V/u right now. (The frequencies listed are correct. It has been very busy for evening passes for the last couple of nites...If your timing is correct, you wont have nay trouble hearing it--even low.
Double check your tracking program keps by going to one of the on-line pass prediction sites.
Hope this helps.
