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.

Subject: [amsat-bb] SA-AMSAT payload activation on SO-67
We intend to schedule the FM V/U cross-band repeater on Sumbandila as
(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)
11:40 (Eastern part of South America)
16:13 (Central Canada / USA)
The CTCSS tone for the transponder is 233.6 Hz.
Use only narrow FM
Switch off compression
Speak softly (mic gain down)
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
