I just discovered that I have a problem with my new (to me) K2. It appears that the antenna switch is stuck on antenna 1. Switching between Ant 1 and Antenna 2 with the feedline on Ant 1 doesn't change a thing in terms of receive signals. The ANT2 indicator turns on when pressing the ANT 1/2 but in reality it isn't switching. The tuner works fine when on antenna one. There are no signals received when the feedline is on Ant 2 and the indicator for Ant 2 is illuminated.
With the tuner out of line (CALP or CALS) and switching antennas I cannot hear the relay switch between Ant 1 and Ant 2. If I put the tuner in AUTO and switch between Ant 1 and Ant 2 I can hear the tuner relays switch. Anyone run into this before? I just discovered this late last night and haven't taken the cover off yet to investigate. In a quick look at the schematic it looks like relay K18 is what switches the ant ports. Curious if this has been mentioned in the past, I did look at the archives and didn't find anything related to this. Any ideas or suggestions? I plan on taking a look at the tuner today and maybe check for voltage on K18. Never having worked on a KAT2 I don't know how difficult this will be to get at.
