KAT500 antenna selection drops to ANT-1 when there is no power on KAT500. Also, with no power on KAT500, the Bypass relay defaults to bypass state. There should be a simple DC path between input RF connector and ANT-1 RF connector if the KAT500 is not powered.
Pull the DC input plug and the coax connectors and measure DC resistance between XMTR and ANT-1. No fancy PIN diode switching in KAT500, it's all relays. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
