The Model 337 Modulator is a proven, reliable design which fills a need for an inexpensive, versatile transmitter with excellent RF output fidelity. The modulator HVPS is a very efficient, duty cycle regulated Dc to DC converter design. Both HVPS and modulator contain modular plug-in subassemblies. A higher power version of the Model 337 (designated Model 527) is available for operation of magnetrons up to 1MW.
