I am sure someone has addressed this before and built … WebOct 7, 2015 · High SWR can reflect enough power back into the radio to create enough heat to cook the final RF transistor. It isn't usually an immediate failure, it takes some time for that heat to build up and do damage. Likely what is happening is that the radio is sensing the high reflected power and throttling back the power to prevent damage.
