Bill,
Download and install the latest K3 beta firmware. The time to power
reduction due to high SWR has been reduced substantially.

I frequently wonder just how much protection a typical SWR protection circuit
can provide against an instantaneous discontinuity if it relies totally on a
feedback approach. If the response time of the feedback circuit isn’t faster
than the risetime of the voltage at the output transistors that results from
a sudden failure, then it isn’t apparent to me how this approach can provide
reliable protection. A well-designed feedback circuit can provide adequate
protection during tune up into a high SWR.
