I have previously written about interference from FM stations on the HO-68 linear transponder. Now it appears the other satellites with linear transponders also suffer from local FM traffic by people who haven’t got a clue that they are transmitting in the satellite uplink segment of the 2 meter band.
This recording was made on Saturday, May 5, 2012 using the Funcube Dongle and Gqrx SDR. It shows very strong FM transmissions on the FO-29 linear transponder from Spain (or Portugal – I can’t tell the difference). The topic appears to be chocolate. If you know who these people are, be sure to send them a QSL card!
