Hi Jim, and all,
Exactly!
At this moment I'm VERY tempted to brew a concoction from these
ingredients:
To these hardware ingredients I would add some freely available
software, such as Pavel Denim's software for the Red Pitaya, plus
PowerSDR, using closed-loop, RF-feedback amplitude and phase
predistortion to linearize the amplifier. The software has this
already implemented.
I wonder is what you are describing here is similar to what I saw on a
commercial FM ya know 88 to 108 FM Broadcast stations new transmitter.
The stations tech would change something on the transmitter, and the
display after the chance ha a spectrum analyzer view-able, and right
after the change you would see the typical wide looking broadcast signal.
But then it would all on it's own tune itself so the output was like in
a solid brick wall, the side skitrts would adjust to the point that they
were darn near vertical! !00% full frequency full power then, BOOM
nothing! No sidebands of any kind at all. Incredible.
