Just finished assembling a KAT2 for my K2. When I started testing I found a  
problem. I only get "HI" on the display in the CALn step, where you are  
supposed to adjust for a reading of 000. Reducing power as low as I can go,  
I can get a "000" display, but as soon as I increase the power, I get "HI".  
I tried CALP and I did get readings that made some sense (a high value for  
FWD and low value for REF power) but the FWD was something like 22 watts,  
which seems too high.

I disassembled and reveiwed the SWR bridge section, counted turns on T1,  
removed the link on T1 and pulled up T1 to inspect the leads and soldering.  
Also verified all the component values and soldering in that area.

So my streak is over. Thought you just finished assembl, turned on power,  
and all this Elecraft stuff just worked! Guess it had to happen.

Any ideas/

Thanks/73,

Tom, KG3V
