[Elecraft] Finished KPA100; problem HiCur and Hirefl

[Koert Wilmink]

Dear all,

After a lot of checking and checking I still have this problem. I 
removed T4 and did dubble check. I did replace the coax cable by a 
teflon coax cable. I did set R26 and R27 to 43K. Sometimes when turning 
C1 it is possible to set 1.0-1 but than it reduces the power to 0 watts. 
After switching off and on again the display is saying Hi Curr again.
I'do not know any alternatives anymore. Please help!
