This was difficult to safely acheive and the most recent hyperthermia therapies tend to aim lower than 42 C.
Oncortherm aside, there are patents that address just that. The thing is to give direction to the RF emission through proper antennas. Gorgun developed a software just to calculate where to focus the RF energy, taking into account skin depth, far mass, skin color, and other factors that influence the delivery.
Rife was using a diathermy machine coupled with a frequency generator. So, it was working on the heating principle, indeed. We know that salt added to water increases its boiling point. So, we could imagine that a frequency may alter the behavior of the diathermy machine and favor an effect before a critical temperature is reached. The Rife effect was always multi-faced, not a single one.

Noise just adds power density. It adds difficult to measure and replicate results. It's better to work with a square wave and duty cycle. And smaller plasma tubes!
