Last night I was finally able to get everything to work and made my first contact through the ISS V/U crossband repeater.
It took a lot of work setting up antenna's in the attic, SatPC32 for the frequencies (TNX to David - KG4ZLB/MØZLB for help with this) and TNX to N5UXT for hearing me and contact (Angelo, QSL is in the mail)!
The pass last night (0420 UTC) was orderly (IMHO) and enabled me to make a contact with a modest set-up - small 435 yagi for RX (fixed AZ and EL) and a J-pole for 45 watts TX - all in the attic.
My wife did not understand my determination to make a contact thru/with ISS before Jan 15 - hi hi
Now on to the sat's!
TNX AGN to David and Angelo! I was like a kid at Christmas!
SatMagazine is a free web based magazine that I get each month. This month's issue is dedicated to Cubesats. They even mention AMSAT and amateur radio in one article. A link to the magazine is attached.
Thanks much for all the great feedback. Its turned out my keps were off in SATPC32 and I just needed to do a quick update. Funny that the ISS was the only SAT exhibiting the problem. Perhaps its orbit/schedule is more dynamic than the rest?
Made 4 contacts yesterday on ISS with relative ease. Awesome big signal coming from there. Loving every second of it. I wish they would keep it going a little longer.

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?
Wayne W9AE replies:
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).

During the last two passes over Europe tonight the
observation is that many use too high deviation.
It makes the audio difficult to read (hear).
Try to turn the mike gain down or use FM Narrow
on the uplink when using the repeater :-)
And another thing - for a QSO to be valid you just need
the call and the signal report.
No need for locator or personal name.
Please no flames.
On Saturday, 10 January 2009, I will have an AMSAT table at the
ThunderBird Amateur Radio Club's "Westfest" hamfest in Glendale AZ.
Just like in 2008, this will be an indoor hamfest on the campus of
the Thunderbird School of Global Management. This campus is on the
southeast corner of 59th Avenue and Greenway in Glendale (grid
DM33vo). The hamfest starts at 0700 local time (1400 UTC), and is
officially scheduled to run until 1200 local time. A map showing the
hamfest site is available at:
More information about the hamfest can be found at:
During the hamfest, I will do satellite demonstrations outside the
building via AO-51 and VO-52 using my callsign WD9EWK. With Drew's
recent announcement about the AO-51 mode change for this weekend
(thanks Drew!), I will be able to show off both the 435.300 MHz and
2401.200 MHz downlinks during the 1429 UTC pass. I will try working
the later AO-51 pass around 1610 UTC, which will be a shallow pass to
the northwest of the hamfest. I plan on trying VO-52 during the 1703
and 1839 UTC passes, with my downlink in the area of 145.915 MHz USB.
I will be happy to send you a QSL card if we make a contact during
my demonstrations. Just e-mail me directly with the QSO information,
and I will drop a card in the mail.
