Mike,
You have already received information on the level of that K1, and I
would not see any need to upgrade the KAT1 firmware.
The maximum power output on 20 meters may be limited due to several
reasons, but the 5 watts does meet specifications. If the actual power
output matches the OUT menu parameter when set to 5 watts or below, the
power control is working.
It is possible that the 22 MHz crystal on the 4 band board is a bit
weak, or you may be able to obtain greater output by aligning the
bandpass filters on the 2 band board.

Hi all,
I'm the proud owner of a K1-4 #1066 that appears to be working very well.
Based on the K1 RF main board, KFL1-4, and KAT1 versions listed below I was
wondering what other eprom revision updates and changes are available that I
should implementing.
K1 RF 2000 Rev D - MCU 1.09e
KFL1-4 Rev B 1.00 (blue trimmers)
KAT1 Rev C 1.20
The K1 power output is showing a solid 5W to a dummy load when OUT is set at
P7.0. Not sure if the output could be increased or if the KAT1 power
measurement should just be re-calibrated.
