The next International Space Station's Expedition 12 ARISS school contact will be with Scouts at the 25th Asia Pacific Scout Jamboree in Thailand on Saturday, 31 December 2005. The event is scheduled to begin at approximately 09:15 UTC.
This contact will be direct between stations NA1SS and E25AJ, so it should be audible to anyone in Southeast Asia and Southern portions of China listening in on the 145.80 MHz downlink. The participants are expected to conduct the conversation in English.
There are several software programs which can
tell you the ISS doppler frequencies, even
without an rig controlled (CAT) transceiver!!!!
For example Hamradio De Luxe (freeware).

Brazilian astronaut Marcos Pontes is tentatively scheduled for a training session at JSC on Monday, January 9, at which time he will be introduced to ARISS operations and school contacts. Pontes is scheduled to fly on a taxi flight to the ISS in the spring of 2006.
during the first ISS voice repeater after its reactivation in occasion of the Russian Space Patrol event, I had the pleasure to contact TA3EL Ali.
It was a good occasion to verify how sensitive the repeater modulation is. In facts, I had to lower the modulation to less than the half of the level that I normally use for other satellite operations.
Also remember that many are willing to try so once you had the contact please leave space for the others.
During normal voice operations I see that many stations use to call after the Astronaut replied to someone else, interrupting their QSO.
This is of course very bad habit denoting poor ham spirit. Those "alligators" will now have to think twice before they choose to eat another QSO because they will have to do it in front of everyone else.
In UHF doppler correction is a must so get ready to learn more about it if you still havent...
I wish everyone good luck with the ISS repeater!
I just received reports (from friends) that
the ISS (voice) crossband repeater is switched on.
The frequencies are:
TXuplink: 437.800 (FM).
TXdownlink: 145.800 (FM).
Do not use too loud mic modulation
otherwise repeater switch off!!!
When you do not correct doppler you -
should NOT operate on the ISS repeater!!!

I had QSO with Bill on 26 December 2005 evening pass over India. It was my first contact on voice with the ISS and Bill. Bill told me that I am his first VU contact :-)
I just worked Bill, NA1SS, during the station's pass over Israel (1637-1640 UTC). Signals were 59 both ways, and Bill told me I was his first Israeli contact.

News received from Kenneth N5VHO:
As part of the Space Patrol special event activities, the Russians have submitted a request to place the Kenwood radio into repeater mode beginning some time on Dec 27 and operating until 0912 UTC on Dec 31 when Exp 12 Commander Bill McArthur will be speaking to Boy Scouts in Thailand.
Cor PD0RKC sent me two maps about the December 25 and 26 passes over Europe.
