Simulation isn't fast but if you let it complete and do an FFT on the last 30 seconds, it's 80dB down at all unwanted
harmonics.
There do however seem to be unwanted sidebands close in either side of 1KHz
Any suggestions for improvement?

Publish a circuit diagram.
Not that hard to make !

If you mean ASCII art, no thanks in the case of this circuit.

Easy to make a screen shot of your spice circuit and upload it one of those free image publication sites

You do not seriously expect readers to start ancient peesees and use millisoft widows emulators to run tea spices

These appear to be LTSpice, so why can't you use it to view my circuits?

As I pointed out, am reading Usenet on a Raspbeery Pi4 8GB
Does everything here from spectrum analyzing to audio to video play
Why boot up an acient peesee to start a millisoft widows emulator
to look up some 80 deebee thingy that likely never has a practical use?

Well, Bessel came up with his functions long before FM broadcasting. Ok you can use Carson's rule but Wikipedia says:
"In 1922 he published a mathematical treatment of frequency modulation (FM), which introduced the Carson bandwidth rule."
Which pre dates FM broadcasting.

While designing my circuit I found this document very useful:

It doesn't mention doing anything in a lab.

In any case if you can't simulate my circuits you won't be able to appreciate how brilliant a designer I am like Bill does.

And elteasprites simu is not worth a thing, reality is different from the models used

Reality is always different from models because models can never have everything that reality has.
But this does not mean that models aren't useful.
Simulation can do a lot to tell you you're going in the right direction.
This can save a lot of time when you get to do it in reality.

I stopped using it long ago (years)
My stuff works.

My sync separators worked too, back when I needed one.
They weren't quite like yours, I think I got an idea from Video Handbook by someone, I forget who.

Just one more thing.
Writing PC as peesee is fine if you're composing something like this:
