Hi Bill,
Yes I agree that it would take a considerable discharge to cause a problem
of this type, however this incident took place during a severe gale, without
any lightning in the area, during a CQ WW. It is a moot question whether the
wind plus rain resulted in the tree becoming charged afte

Duane,
Have run into the same thing as others have mentioned. Should you need to
replace the two diodes in question, you may want to consider mounting them
on the opposite side of the board. I found they were easier to replace,
should you have to do it again.
The best thing to eliminate this pro

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 faile

Yes. In my case D16 and D17 of the KPA100 had failed. These are the
diodes in the swr/power monitor. When the K2 controller doesn't get a
power reading it just keeps on trying. Eventually you reach the
current limit.
On a slightly different topic, a
Hi all,
I left the K2 antenna plugged in today and went to work.
We did get a fast moving torrential downpour with some lightning
activity in the area where I work which is about 20 miles north of the
shack.
So I'm not sure if there was any lightning in the area of the shack.
