[Elecraft] KAT500 antenna port isolation

[ANDY DURBIN]

" From your explanation, it sounds like you've switched the active KAT500 antenna port to a dummy load on which you're hearing a local 6m station.  If that's correct, I don't believe you're looking at port isolation, you're just receiving a local guy on your dummy load, which wouldn't be at all strange.  What did I misunderstand here?"


I don't think you misunderstood anything but I don't know how you decided the signal is through the dummy load rather than coupling in the KAT500 from the antenna port to the dummy load port. I don't remember hearing local stations on the dummy load when using the Alpha Delta switch.


I suppose the only way to get good isolation data will be to do a sweep of the KPA500 and Alpha Delta switch with the SA+TG. If I do that I'll share the results.


For now I'll enjoy the automatic antenna switching.
