Unfortunately, 70cm UHF doesn't lend itself to unattended SatGate
operations like 2m VHF does. I tried catching the ISS on UHF and only
managed to hear, but not decode, one packet burst. I can't imagine
anything short of a full satellite station with automatic

There's a lot of sites out there listing the original 145.825 frequency
for the ISS APRS frequency, but if you look closely at the spot reports
at http://www.issfanclub.com/packet-reports you'll quickly notice that
it's operating on 437.550 UHF at the moment. As it says at
Or if you're an APRS user, just send an APRS message (any content except
a valid APRS callsign-SSID) to ISS. The response will contain the next
pass information for your last beaconed position (or the last beaconed
position of the callsign-SSID that you send as the text to ISS).
Just noticed that KD2AUC-1 got a packet through the CU3HY IGate in the
Azores!

K6RPT-11 is currently being gated by EA7FQB to the rear and EA6WQ-10 to

The battery voltage is climbing as is the altitude as the balloon

I've sent APRS messages to the CT1AKV and EA7CRT IGates in Portugal and
Spain respectively, but have so far only received acks but no human
response. Hopefully they'll see the messages and possibly switch over
to 144.390 to receive the balloon if/when it gets that far.

Negative. The split 9600/1200 frequencies were published on FASTRAC's
original page at
http://fastrac.ae.utexas.edu/for_radio_operators/overview.php
However, the announcement of the digipeater availability at
http://www.uk.amsat.org/2011/12/01/fastrac-1-digipeater-activated/
supersedes this
So, with that confirmation coupled with earlier 1200 baud confirmations
on 145.825, it would seem that the 1200/9600 baud uplink frequencies
published on the original FASTRAC page are backwards.
