Because I have got (a long time ago) a modified LNB I started with receiving ATV on 3cm. The only station I could receive with a 35cm offset disc, was PI6ATV, about 35 km from here. And YES I received the ATV repeater with a B5 signal, in analog as digital mode. See pictures below. These pictures are taken before the great move in the tower of Ijselstein (2016/2017)
Later on I tried to receive the repeater in Zoetermeer and also I received the picture. In 2017 PI6ZTM moved from Zoetermeer to Den Haag but the signal was very weak (B1) so I have to improve my antenna situation and therefore I bought a bigger (60cm) parabolic antenna. On a separate page more about my antenna’s.
On internet I found a small motion detection module (HB100) that was easy to modify to a 3cm transmitter, thanks to PE1RKI and PA1SDB. The video quality is very good. The lowest possible frequency was 10.243 MHz with the tuning screw removed. Video was made by a Raspberry Pi with the Python program tstptn.py.
