Re: FO-29 telemetry

Hi Mike, DK3WN

Your FO-29 telemetry of Feb, 2006 at 1614 UTC demonstrates that actually
FO-20 is working nominally.

Unfortunately despite the boombing signals there is small activity on this
satellite and to day the only station I have worked in SSB during all the
South-bound and North-bound orbits were Rolf, DK2ZF , SV1JGW, EA3DME
and 2E1EUB

Tanks for your help

Hi Mike, DK3WN

Tank you very much to decode the FO-29 telemetry. It seems that
all parameters are nominal and the batteries are charging but it should
be necessary to compare the actual performance with some old telemetry
file that you probably have available in your archive.

Please let us know
