CUTE-I (JQ1YCY) CW beacon on 436.8375MHz. FM Packet: 437.470 MHz

XI-IV (JQ1YCW) CW on 436.8745MHz 100mw. 1200bps FSK AX25 Packet: 437.490
MHz

QUAKESAT 436.675 MHz, FSK +/- 3 KHz dev, 9600 baud AX25 packet each 10
secs
http://www.quakefinder.com/quakesat.htm
CAN X1 436.88 MHz The beacon is a digital signal consisting of two tones,
one at 1.2 kHz and another at 1.8 kHz. SSP format. Please send your
reports
to dkekez@utias-sfl.net Web info @ http://www.utias-sfl.net/
DTUSAT is on 437.475 MHz (2400 b/s) We expect to receive the first beacon
with telemetry tomorrow morning. We do have a pass tonight, but as the
satellite batteries are not fully charged at the launch, we will wait
before
deploying the antennas. The chances for receiving signals tonight are thus
marginal at best, but we will of course be listening for its first words.
DTUSAT sends burst of data every second min. Every 5th burst should be
CW -
but with a 1200 Hz tone so that it can be heard on a FM receiver. It will
send OZ2DTU DTUSAT at 13 words/min.
Later it will configured to function as a flying signal generator dropping
the level for each burst. This way we can use it to test our receive
system.
The DTUSAT group said that they would use: observation@dtusat.dtu.dk and
check http://dtusat.dtu.dk/

You should be listening for at short signal-burst every 2 minutes.
Alternatively a morse signal repeating every 20s (if something is wrong).
Any information is appreciated. If anybody hears the signal, please answer
to lalm00@control.auc.dk with as much information as possible.
Some more information about the signal is available from our homepage:
www.control.auc.dk and general info at http://www.cubesat.auc.dk
