RAFT status
by Robert Bruninga 21 Dec '06

21 Dec '06

RAFT STATUS: RAFT is operational for over 2.5 hours and telemetry shows the system operational with battery voltages slowly charging up. The first pass showed volts halfway through eclipse at 7.3, but the second pass showed volts further into eclipse gaining at 7.8 volts. Full charge is 8.4 volts. Telemetry shows we are getting a low-power shut down before the end of eclipse since the telemetry counter is re-starting at the start of the sunny side. We expect voltage to continue to improve and so are doing no commanding at this point. Temperatures were about 0 deg C on the first pass, but improving to about 2 deg C on the second pass. Signals require a good oscar array, and we could use some Additonal telemetry. Just send anything you get.

RAFT Deploy...
by Robert Bruninga 21 Dec '06

21 Dec '06

RAFT and NMARS were deployed at 01:56:49z on 21 December 2006. They have a very high spin rate. NMARS is spinning at at least 60 RPM and RAFT at maybe half that. This will make getting a complete 1 second packet difficult due to fading on linear antennas. De WB4APR, Bob

First RAFT packets maybe over Australia
by Robert Bruninga 20 Dec '06

20 Dec '06

Australian Hams should listen for RAFT separation at 0156 UTC. Present predicts show RAFT being deployed on a pass over Sydney, with the satellite appraching the ENE horizon. Australian hams might hear one or two of the 145.825 telemetry packets before LOS. Please report any packet received to bruninga(a)usna.edu direct so I get soonest copy. Thanks Bob Bruninga, WB4APR USNA Satellite Lab

Propagation?
by Dave Johnson 20 Dec '06

20 Dec '06

Hello List, Being relatively new to the satellites (I started successfully only a few weeks ago), I have a question. During last night's (Tue, 12/20/06) evening passes of both AO-51 and SO-50, I was pretty much unable to establish contacts. On AO-51 I did get a reply from VA7VW, whom I worked a day or two earlier with no problems, and this was toward the end of the pass at my QTH. Both passes were well-placed (in fact, SO-50 was at 85 degrees elevation at my QTH), yet I had very poor results. Hearing the satellites was not a problem, only contacting them was. Having been successful on all of my earlier tries, I am wondering how often you've noticed being unable to get into the satellites? I'm running 5W on an HT, so that would obviously be a factor (higher power being able to make it easier), but since I haven't experienced all possible conditions yet with Sat ops, I'm still building up the familiarity with how certain conditions arise. This morning, I have noticed that some of the FM stations had more static than usual (for the fringe ones), and on 2 meters, one of the remote repeaters that I usually get well from about 40 miles out was hit or miss as well at times, so perhaps there are some propagation issues currently. Anyway, thoughts and comments would be welcomed. Thanks and 73. Dave, KC9GHA.
