[Elecraft] KAT500 ANT1 problem

[Andy Durbin]

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.
