This is a known issue, according to Gary Surrency in support. He says
that some RF on 80m (and on 160m) is getting into the Current (& Voltage)
Sensing circuit(s) on the K2 Control board. He suggests adding to the
value of C42 on the Control board to increase it to at least 0.1 mFd.
This will alleviate the problem. The best place for the new (or
additional) bypass cap is directly between pins 4 & 8 of U3.
Because these false current (and voltage) fluctuations occur, they they
might exceed your CAL CUR setting on 80m and cause a HI CUR indication.
