Excellent 19 deg pass over VK/ZL at 2138 UTC. Very strong downlink signals up to 60db over S9 for most of the pass. Could hold the transponder in at less than 1 deg. Worked Graham (VK2AYE) and no problems using the recommended technique.

Hello
We intend to schedule the FM V/U cross-band repeater on Sumbandila as follows (all times in UTC; all activations 13 minutes duration):
Fri 6 Nov 2009: 21:38 (Eastern Australia / New Zealand)
Sa 7 Nov 2009: 02:05 (Western Asia) 08:17 (Europe) 11:40 (Eastern part of South America) 16:13 (Central Canada / 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 Saturday.
