Abstract
A method and apparatus for simultaneously operating two diathermy treatment heads in close proximity without interference caused by phase and frequency differences. Each diathermy head has a drive circuit powered by a master oscillator providing RF energy. Each head can be used alone with RF drive from its own oscillator. When the heads are to be used in close proximity, they are coupled by coaxial cable, and one oscillator is automatically disabled to permit the other oscillator to furnish the RF drive for both systems. The RF drive is then coherent in phase and frequency in both systems, so the two diathermy heads do not 'fight' each other.
