TV transmitter VHF Bands I, II, or band III

This TV transmitter will handle frequencies up to about 250MHz, so it will work perfectly if you have on your telly. In principle, the transmitter should work up to 500MHz or more, using the BF959 bipolar transistor. You should be able to generate a signal on UHF channel 21, but I have not (yet) tried […]
