Just to close this thread in case anyone was wondering about it, I
installed the KPA100UPKT today and it solved the HI CUR on 30m problem.
The K2 now draws less than 1.7 A on 30m with 100 W tx into dummy load
compared to 4.1 A before. What a nice change. My thanks to Don and the

Mike,
First, count the number of turns on L4, L5 and L6 in the KPA100 - count the
turns that go through the center of the core rather than the outside. An
extra turn on these windings would produce the Hi-cur on 30 meters.
How old is your KPA100? If the kit was ordered mid-2005, then you may ha

You mus
I just noticed I'm getting a Hi Cur message only on 30m.
The set up:
- K2/100 into dummy load (KAT100 disconnected)
- Power set to 100 W
- CAL CUR set to 3.50 A
- When CAL CUR is 4.10 A, current drawn on 30m levels out at 4.02 A
- When I drop to 85 to 90 W, 30m draws just under 3.50 A
- All othe
