David,
Your CAL CUR setting is limiting the power output. Yes, the current is
trying to be excessive and the K2 cuts back on the power to limit the
current. The Hi Cur message says that the microprocessor has done just
that.
Most of the time the cure to that problem lies in the low pass filter.
Check the K160RX board toroids for the correct number of turns (count
the number passing through the center of the core), check the capacitor
values and check your soldering.
If you continue to have trouble, check T4 as well.

Hi all
I Noticed that during the cq 160m contest this weekend
that I could not get more than 4 watts out of my K2
The Requested power goes up to 15.2 of course but I
cannot get more than 4 and on the first transmit I get
a momentary Hi current. My power supply is steady on
voltage and current. I switched the display on the K2
to display V/I and the voltage drops on transmit and
the current goes up to about 2.4. This is within the
Cal Current range. Now on 40 meters it is fine it puts
out 14 watts. same with 30m. I haven't tried the other
bands. Also the Requested power on 160m does not match
at any request of power through out the range from
lowest to highest. Is this connected?
Thanks
