[amsat-bb] Payload A tonight

[A Thomas <70374.440@xxxxxxxxxxxxxx>]

Following received from payload A tomight at 18:58:14 (locked to dcf77)
with Kenwood TMD700Eon 145.825 and PACKCOM 9k6 with TRACE ON. Elevation
comig up to 88 degrees - yes really - just after this packet but spacecraft
then in eclipse. My locator IO92NL

Previous bursts heard approximately at 55 second intervals but Doppler
shift is very bad at 9K6.

I have made some progress with decoding the hex. Using Windows calculator,
enter the number above as hex and then check the decimal box  and you will
get the ascii code; then open Word and hold Alt while entering the number
off the number keypad. However sometimes the decimal number should be
divided by 2 to get the correct ascii code. Using TRACE ON therefore gives
the possibility of getting data successfully from the satellite, although
we need to investigate it more. It will be relatively easy to write a small
program in VB to do this (relatively easy for some, not me, that is...)

Wihe memories of Starshine 3, can I please respectfully advise future
satellite builders to use 1k2, as the Doppler on 9k6 is awful if. like me,
you have to use 5kHz channel steps...

Mit freundliche Grüssen aus England nach Deutschland

A happy and peaceful New Year to all Amsat-bb-ers
