[Elecraft] Broken relay in KAT2

[Charles Greene]

Hi,

One of the relays in my KAT2 is stuck or a relay contact is shorted. When 
you select antenna 1 it is ok. When you select antenna 2 both antennas are 
selected (bad), and the indicator stays on Ant1. I guess replacing the 
relay is necessary. I don't know why it stuck. I first noticed it this 
morning while running the 5 watt beacon on 14102 KHz testing my EH antenna 
against my Hustler 6BTV vertical. Both external SWR meters read and the 
antenna was detuned. The beacon software is not supposed to hot switch, and 
the SWR on both antennas is less than 1.8:1. I have been running the beacon 
for over a month, and it switches antennas from 1 to 2 and back to 1 every 
5 minutes. We have had only one lightning storm since the summer, and that 
was about a month ago. My K2 is S/N 462, but it has not seen hard or 
frequent use. Seems the relays should be good for more cycles than that.

  Any suggestions which relay is malfunctioning or why?
