Hello Martin,
looking at the manual of the QO-100 Groudstation of DX-Patrol indeed it shows that the transverter is working only simplex.
AMSAT-DL has made very clear for a long time than full duplex operations is requested by users who want to use QO-100.
DX-Patrol is making money by leveraging the investment others have made by implementing the QO-100 ham radio satellite
and they should respect the rules given by the operator of QO-100. Yet it looks like they are simply ignoring it.
I think this is very disappointing!
We can already today see the problems many people, who are using simplex operations, have to demonstrate proper operation.
They talk over each other frequently without noticing. In pileups it is quite easy to distinguish those with a proper full-duplex setup
and good operating skills from the others.
Hopefully many radio amateurs will understand that this transverter is not compliant to the requested operation mode on QO-100
and will thus choose one of the many other better solutions.
Kind regards
Matthias
