KAT500 cycling

[Jack Satterfield]

I leave the KAT500 on 24/7, several years of perfect operation.

Today I sent the usual 15 watts tune carrier on 75 meters the tuner started
cycling

all lights on and off. Turned the tune carrier off but the tuner continued
to cycle.

Tuner will only turn off by removing power. Plug power back in it starts
cycling.

 

Sounds like a trip to Elecraft but thought I would ask here to see if there
is anything I

can do.

 

Thanks,

Jack

Thought I would report the solution, tried a different power supply to the
tuner.that was it.

When my KAT500 started acting strange I opened it up.  There are two
thick, green insulated wires that cross each other on the PCB, and the
top one had sagged down and got close enough to the bottom one that it
had arced through the insulation.  I'm guessing I had a less than
optimal match!  Anyway after consulting support, I gently separated the
two lines and put a double layer of electrical tape between to hopefully
prevent recurrence.
