What is the cheapest WBFM microwave station I can make?
If you just want to experiment, and would be happy with voice communication for 8 Km or less, you can be working for about $US50.00. Of course, you will need two stations (one on each end), but if each station has a Gunn source with a schottky detector and a 6 db horn antenna, a simple modulator/power-supply (sold above), a good 88-108 mhz FM radio to be used as a tunable I.F. strip, a cheap set of computer-style headphones/mike, and 12 vdc at 500 ma, you can be having fun! Adding the heater kit (sold above) will allow for much less re-tuning to stay in-touch with the other station for hours on end.
