[Elecraft] KPA100 power question..

[Jay & Jac]

Hello all,

I just completed the KPA100 on K2 #279.  All went well until I did a power
output calibration at 50 watts at a friends house who has an accurate
wattmeter.

The problem is I cannot seem to adjust R26 to match the actual 50 watts (as
shown on the watt meter) to the power control on the K2.  The power control
pot on the K2 shows 12 watts lower than is actually being put out
consistantly throughout it's upper range.

Have I made a cockpit error somewhere?
