Yesterday I had a remarkable QSO with Hans, PE1DWA.
We had set up a duplex ATV connection and a duplex voice connection.
For ATV we used the repeater frequencies of PI6ZTM (10,150 GHz out, 1255 MHz and 433 MHz in).
For voice 2 meter and 4 meter band were used: 144.750 MHz and 70.450 MHz.
So in total we used 5 different frequencies. At least remarkable.
I made a map this event:
Except for the ATV transmission on 70cm (which was in AM, one suppressed sideband) all transmissions were in FM.
