We intend to schedule the FM V/U cross-band repeater on Sumbandila as follows
(all times in UTC; all activations 13 minutes duration):

Sat 7 Nov 2009:
22:46 (Australia)

Sun 8 Nov 2009:
00:05 (Japan)
00:21 (Australia)
00:58 (South America)
03:15 (Central Asia / India)
07:59 (Europe)
09:34 (UK)
12:56 (South America)
14:18 (Eastern USA)
15:52 (Central USA)

The CTCSS tone for the transponder is 233.6 Hz.

Uplink:  145.875MHz
Downlink:  435.345MHz

Additional recommendations:
Use only narrow FM
Switch off compression
Speak softly (mic gain down)

Satellite characteristics:
All antennas are linear vertically polarized (1/4 wavelength)
Sat Tx power = 5W
Sat Rx sensitivity = -116.5dBm for 12dB SINAD
Max antenna gain = 4dBi

Note that the satellite is currently in a controlled sun tracking mode with
antennas Nadir pointing.

Apologies for the late notification, but we're still in the commissioning
phase and can therefore not guarantee the SA-AMSAT payload service far ahead
in time.  Since we're using the same (shared) transponder for TT&C purposes
at present, we can unfortunately not schedule the payload over RSA on
