[Elecraft] KPA1500 wattmeter adjustment

[Steve Masticola]

If you dig into the QST reviews, you'll find out that the LP100 did not quite meet its spec of 5% accuracy on all bands at all power levels and modes. But then, neither did the LP500 nor the W2.
The old Array Solutions Powermaster II came closer than any of those three. it was within 5% everywhere except at 5 watts CW at 50 MHz.

The W2 was reviewed in the July 2010 QST.
The Array Solutions Powermaster (not the II) was reviewed in the January 2006 QST.
