[Elecraft] KPA-1500 Power Output Variation

[n4cc at windstream.net]

Why worry about it?  No one on the other end would be able to tell one bit
of difference.  I see power drop -- maybe 5 - 10 percent -- as the KPA1500
heats up...likely normal.   The small bit of reflected power may also have
some minor effect on the wattmeter readings you see as well.  73, Greg-N4CC
