KPA100 IMD Distortion Figures

[Wyn Hughes]

Hello Group,

Has anyone measured, or have any information, regarding the 3rd/5th order IMD performance of the barebones KPA100, based on a two-tone test?

I have some figures for the base K2, courtesy of the ARRL review. I might even have seen figures for the K2/100, but can't seem to locate them at present. If anyone can also supply these figures, I would be grateful.

Take a look at the tests run by Jack, K8ZOA, using his Z90 Panadapter
kit at cliftonlaboratories.com Click on the IMD Measurements link. He
shows the test methodology, and results from several rigs, including his
K2/100.

Thanks, Larry, those figures are in themselves impressive. Of course, a lot
depends on the mesurement equipment and conditions. Worth adding perhaps to
the Elecraft resource list.. My L-4's -33db compared to single tone (-39db
cf. pep), would in that case be the limiting factor. Maybe a good excuse for
a new rig.
