[Elecraft] D19 shorting out in K1

[Jim Ragsdale]

I've been wondering if anyone else has experienced this. I have a K1 
with the KAT1 ATU and am using an A/B switch to swap antennas. Three 
times now when I swap antennas with the power on the K1, it shorts out 
diode D19 in the final. I can solve the problem by always powering down 
before the swap, but sometimes I forget to do that (has nothing do with 
my age. HI).

Any thoughts?
