Subject: [jamsat-amsat-bb:20408] SEDSAT Up at 6:57:14 UTC 10/28

Hi Everyone,

Just thought I'd post a quick note to say that SEDSAT power cycled somewhere
between New Zealand and the US last night, and came up shortly after.  I have to
figure out exactly how much later yet, but I believe we'll only know to 15 minutes
or so.  

I've been receiving several reports from people receiving telemetry, and
reporting uptimes.  The uptime on the satellite indicates that it came up at
6:57:14 UTC on 10/28 (right when it came up over Tucson, shucks!)

It seems from trends this week that it will be up approximately 23 hours, so
expect it to go quiet again around 6:00:00 UTC on 10/29.  And if this trend
continues, it should be back on the air again around 16:00:00 UTC on 10/29.

No one in the states had a chance to test the uplink last night, and I don't
believe anyone else has the detailed information.  We should probably get that out
soon.  I was planning on surveying those who are reporting telemetry.  What you
need is capability to transmit at 1266.9 (and doppler tune), 9600 baud FSK packet,
but with 10-15Khz deviation (instead of the standard 3Khz).  If you meet this
critera, and have a machine capable of running a DOS program to test the uplink,
please let us know at telemetry@seds.org.

Also, for those that requested it, we'll be putting the telemetry formatting
standard online soon (by tomorrow).  It appears as if those logging KISS packets
aren't retaining the binary information, as all the high-bit characters aren't
representable in ASCII.  I don't believe the WiSP feature of logging KISS packets
works either, but I haven't verified that.  We're getting there, bit by bit
(literally :)
