[Elecraft] KPA100 Power question

Sat Mar 15 10:08:01 2003

Hi

No. You do not have R26 set right. Assuming your Bird is accurate you need
to make the K2 wattmeter read the same as the Bird. Adjust the K2 power for
50 watts as indicated on the bird then adjust R26 until the K2 display reads
50 watts. Readjust the power pot slightly after each change of R26 so the
MPU will reread the power out. If everything looks good check at 100 watts
and readjust R26 a little to bring the meters into agreement. Make very tiny
adjustments of R26 on the order of only 1 or 2 degrees. Once R26 is set,
adjust R27 to about 20% more clockwise than R26. Just eyeball it or, with
the power off, measure R26 with an ohmmeter and set R27 to 20% higher
resistance.
