TUBE AM CIRCUIT For many years, AM transmitters used vacuum tubes for the power amplifiers and for the driver circuit. A simplified AM transmitter circuit is shown in Fig. 1. The DC high voltage ...

A crystal radio is a common enough science fair project, but the problem is, there isn’t much on anymore. The answer is, of course, obvious: build your own AM transmitter, too. AM modulation … ...

Bust out that 555 timer and use it to build your own AM radio transmitter. The circuit that [Rtty21] is using only needs the timer chip, an NPN transistor, three caps, three resistors, and a potent… ...

Field tests are described which investigate the transmission of compatible-single-sideband signals from a typical high-power transmitter for high-frequency broadcasting and which compare reception ...
