ATV in the 70’s was usual on the 70 cm band. I modified the tuner of a portable TV so that it I could reach channel 17, that was the channel where I could receive a lot of ATV stations from Amsterdam and surroundings. However, it was necessary to put a preamplifier between antenna and the tuner. In that time I made much duplex QSO’s with ATV stations, such as Hans, PA0ORI from Amsterdam. Also sometimes spontaneous DX appeared…..
