Bill,
I cannot assure you that this is not some delayed effect of the
lightning strike,
However, try doing the TX Gain Calibration before anything else. You may
want to run it 2 or 3 times if it does not help initially.
If that does not correct it, you will have to contact support for
further assistance.

My K3 SN 1502 with MCU 4.83 is exhibiting a strange surge in transmit power
level. When the rig is keyed in CW with the power set all the way up power
output surges from a high of around 140 (!) watts down to 60 watts and back
in a rapid fashion. It is at it's worst on 30 meters shows at least a high
power spike on all bands except 160 and 80 before it settles down to around
100 watts. If I turn the power down the cycling is much less severe but
there is still a leading spike of around 140 watts. I have tried reloading
the firmware with no luck. I have checked all my jumpers and connections
and they are fine and the rig does this even straight into a dummy load. My
power supply is an Astron RS-35M in great shape.
I should mention that we suffered a lightning strike last Labor Day weekend
that took out my Ten Tec tuner, W2 wattmeter and a few other things but the
K3 was not affected at all and I hope this problem is not some delayed thing
from that strike!
An ideas? The rig is almost six years old - maybe I need to open it up and
make sure screws are all tight?
