[Elecraft] k2 clicking

[Ron D'Eau Claire]

Assuming you meant KPA100 and not KAT100 -- It seems that almost always the issue is failed diodes in the power detection circuit used to measure SWR and drive the tuner - apparently from static discharge from the antenna. In this case, the KPA100 diodes have failed. The KAT2 diodes appear to be fine since it works. 

High Current is a common report coupled with bad diodes. The KPA100 uses the forward power sensed by the diodes to set the output power to match what you have requested with the POWER knob. No feedback means the rig drives the finals to full output, often looking into a high SWR since the diodes are also necessary for the tuner to work.

ok the relay that switches the high power was clicking because the fuse in 
the rig runner was bad replaced that stopped clicking think problem in kat 
100

Left k2 hooked during storm now acts funny. Have the k2 with amp and tuner
in ec2. Tuner tunes but leds on kat100 don’t light up. Also shows hi curr on
screen. KAT100 shows error code E243. When kpa100 switched something starts
clicking one of the relays not sure which one yet. kat2 tuner shows no
errors just when kat100 hooked up.
