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.

73,
