PCSAT2 Digipeater & Telemetry

Hello Group,

ISS just passed over West Malaysia at 0908 UTC, 1st September 2005 with a
maximum elevation of 12 degrees.

During this pass, the ARISS system was beaconing on 145.800 MHz but I did
not hook up the TNC to decode this.  Instead I was listening to 437.975 MHz
+/- to get a copy of the FTSCE special 9k6 data.  However, nothing was heard
on this frequency.  

Next, I decided to QSY to 435.275 MHz +/-.  Telemetry and status messages
were received.  They were transmitted using 1k2 baud as well as 9k6 baud.  I
managed to copy a few telemetry packets that were fed to the APRS network.  

In addition to the above, I also managed to successfully perform a digipeat
via PCSAT2 and TX on 145.825 MHz.  Signals were weaker on 435.275 +/- as
compared to 437.975 +/- but still I still managed to copy it.  Later, QSYed
back to 437.975 +/- until the pass ended.  Nothing heard on this frequency.

Anyone knows why no FTSCE data are transmitted on 437.975 MHz?  Or is it
something wrong with my setup?
