[Elecraft] KPA1500 Linearity

[K9MA]

I recently ran a two-tone test and measured CW power gain. (SN1078)  It 
doesn't look good.  The two-tone waveform shows distinct "flat-topping", 
and the power gain drops 25 percent from 1000 to 1500 Watts.  My old 
3-500Z amplifier is much better.  Has anyone measured IMD or linearity, 
or seen any test results?

While I'm primarily a CW operator, I'd be very reluctant to use the 
amplifier on SSB.
