Chris,
The LoP message indicates that there is not enough power to tune the KAT2.
As your first troubleshooting test, unplug the KAT2 (both cables) and
try again - connect a dummy load to the lower BNC jack on the base K2.
See if you get power output on 10 meters. If not, look carefully at the
bandpass filter for 10/12 meters.
If the bandpass filter is OK, then you will have to do Transmit Signal
Tracing. Build the RF Probe if you have not already done that and turn
to the Troubleshooting appendix in the manual. Do the troubleshooting
on page 14. Use 10 meters instead of 40 meters, and tell me at which
point the RF voltage is significantly (more than 10%) less than the
expected voltage.

Hi folks, I'm done in the building of my #7855 K2 and his KAT2.
I've got a problem on 10 meters.
For example I put the VFO on 28 360 Khz and I press down TUNE, to tune.
The screen shows a "Low P" message. When I try to transmit on this band, where
is no power at all, the S Meter not move at all. (Problem with my antenna connected even
with a good 50 ohms dummy load). All is good on the other bands.
My K2 is KAT2 and KSB2 equiped.
Some idea on where investigate ?
