[Elecraft] How susceptable is K2 to antenna static shock?

[Geoffrey Mackenzie-Kennedy]

> Has anyone seen the K2 act like this before?

Yes some years ago, after a falling pine brought down the antenna in use 
while the K2/100 was transmitting (CW).  Diodes D12 and D14 in the KPA100's 
T-R switch both failed into a shorted condition, and one of the diodes in 
the K2's T-R switch failed as well. I was very lucky that the KPA100's 
transistors did not blow. My K2/100 now shares a protective shutdown system.

I suggest that you do not use the transmitter until you have checked out the 
T-R switches in the KPA100 and the K2.
