Please check in SSB mode.

happy with the harmonics.

No idea about the power.? ? ?? Next time I make a change I'll try a few different cables, jiggle things, etc...

Is there a good way to characterize with SSB?
I was excited to see the ARRL testing book, but very disappointed by the reviews.

Hello John,

Great and useful data.

Based on the harmonic frequencies and levels I concluded this was done in CW mode.
Is this correct? If not, how was the test done.

I also notice the power values of the fundamental varies quite a bit between tests for the same band. Can you shed some lights as to why?
