Michael,
You said the 'magic words' - HI CUR, Hi REFL messages and lack of power
control (other than low and high power selection) *after* a lightning storm.
That is an indication that the lightning surge zapped diodes D16 and D17
in the KPA100 wattmeter - the result is that the base K2 microprocessor
*thinks* there is no power output and increases the drive until it 'runs
out of gas' - the K2 will produce max power output under those conditions.
Replacement of D16 and D17 is in order as a first step. If that does
not cure things, then we can help you troubleshoot it further.

Hi,
I've been using my K2/100 for many months with great results. After a
recent storm containing lightning the next time I fired up the K2/100 I
received the "HI CURR" message and the "HI REFL" messages upon initial
transmit. This was unusual, so the next thing I did was consult the
troubleshooting guide in the KPA100.
Using a wattmeter and connected to a dummy load, I measured the output
power of the K2/100 with the power outupt contol set to less than 11
watts and noticed that for a setting of 5 watts the output of the K2/100
was about 10 watts. For a power output setting of 15 watts, the output
was very high - about 100 watts.
