AM Micropower Transmitter
Advertisements
The picture to the left is a high quality radio transmitter for the A.M. broadcast band. The transmitter legally operates with “micro-power” and will not set any distance records but, unlike simpler designs, the frequency stays put and the fidelity is excellent. Although the schematic looks somewhat complex, the circuitry is easy to build and adjust for experimenters with a little “tweaking” experience. A simple output meter confirms proper signal level and checks antenna tuning while “on the air”. Add an audio mixer, tape recorder, and perhaps a CD player and have a near-professional micro-power station.
