Hello again, Hmm, that should produce similar results to mine. One possibly important difference is that the VNA ports are perfectly matched 50ohm ports, but that shouldn't make that much of a difference. Have you ever tried to connect a dummy load to one of the ports (leaving the KAT500 in the normal shack wiring otherwise), select it and see how much stuff leaks through from the other two ports? I will send you an E-mail so you get my E-mail address. But I don't doubt your interpretation of the scans.

Email me and I can provide those scans if you'd like. > > Phil - AD5X > <snip> -- View this message in context: http://elecraft.365791.n2.nabble.com/KAT500-schematic-tp7568007p7568063.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
