Looks pretty good. If you have a tone generator, you can get a better display of the peaks and valleys. Some guys whistle a tone, but I wouldn't do too much of that on an antenna.

But I don't know how to correct that with my ftdx 3000. Here is a video of the audio sampled with amplifier putting out 600 watts. And a freeze Fram pic that does look good.

I'm connected to an unused antenna output (antenna #2)on an ameritron atr 30 tuner and transmiting on antenna 1. Basically just using the coupling effect to sample the rf..with out having to make or buy an rf sampler.
