[Kenwood] two tone test question

Thanks for the response and info.
Yeah, the two tone test would require the xcvr to be in SSB mode. Don't
know where my head was on that one.
I have a '68 Handbook, and it does go into some detail about the principles
of the two tone test. But, it doesn't have anything about the effects that
audio and rf underdrive/overdrive are expected to have on the test pattern.
I guess rf overdrive and IMD distortion are closely linked; i.e. if the
pattern is almost a perfect trapezoid, I shouldn't have IMD distortion or rf
overdrive if the pattern is good.
With what you've told me, I think now I can do it OK. I think a perfect (or
very close to it) trapezoid is what I'll be looking for.
