[Elecraft] [KPA500] No power out in "OPER" mode

[Dave Johnson]

Larry

If you use ALC between your KPA500 and your transceiver, check to see if
there is a permanent output from the KPA500. U8 on the KPA500 control board
is a known issue where the wrong part was specified up to at least serial
573 (mine)...

The fix is to obtain the correct part and replace it. A work around is to
not use ALC.
