Re: FO-29 telemetry

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

Tanks and 73" de
