I concur that the RF sense works very well, at least it does with an external antenna switch and reasonably good antenna SWR. I am not sure what happens if you also use the KAT500 as an antenna switch or your untuned SWR is very bad. Does the amp fault during this first dit?

All it takes is a dit or a tap on the mic. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
