NOT USING modern equipment but attempting to spout off like you have
some knowledge of what is being discussed is making you look like
N0IMD's antenna advisor.

That would be Kellie...whose only "engineering expertise" seems
involved with antenna support structures.

Leonard, you can't seem to get anything right of late. Kelly's advice
was totally rejected by your little electrolyte, "William". Brian posed
you a question which had nothing whatever to do with "antenna support
structures". Did you come up with the answer yet?

Kellie not know much
of the innards of frequency control subsystems in a modern radio
so he tries to misdirect onto his mechanical thing.

He certainly knows more about them than you as evidenced by your
comments on phase noise compared to his.

Do I have knowledge of modern frequency control subsystems of
radios? Yes, considerable.

That hasn't been evident in light of your comments on the importance of
low synthesizer phase noise.

Such applies to all radios, not what
a designer-maker has labeled "amateur" as (as you imply) being
somehow different than other radios.

Amateur transceivers are, for the most part, quite different than
transceivers designed for point-to-point use.

Some rigs--Ten-Tec's Omni V, Omni VI and the main receiver of the Orion
are amateur band only transceivers.

No amateur radio license is required to acquire knowledge of
radio-electronics technology.

Lucky for you!

No amateur radio license will let
you legally radiate RF outside of amateur bands (beyond the
incidental/low-power government limits).

And?

In most U.S. radio
services no federal license is required to use those radios.

Sounds like a plan for you. Grab a job in one of those services and
operate like crazy.

You didn't seem to have any comments at all about your comments on phase
noise as compared to reality. My comments to you we

"Once again, you've demonstrated that you know very little about
problems
with much of the amateur radio equipment produced within the past couple
of decades. Noticeable phase noise appears not only in the receiver
output section of many transceivers but in the transmitted signals as
well. 1980's top of the line Kenwood TS-930's were rife with the phase
noise products and synthesizer spurs. A quick spin of the main tuning
dial with no antenna connected would result in a rapid p-t-t-t-t-t-t-t-t
sound from such spurs. R.L. Drake's TR-7 had much less phase noise.
Rigs such as Ten-Tec's Omni VI series, using a crystal mixed front end
had almost no measureable phase noise."

One of the Polish fellows has published some excellent information.
