I quote your message:

"Amplitude Modulation... The output level "swings" above
and below the carrier level."

This is incorrect. The output does not swing above and
below the carrier. The output of an AM signal is the
carrier and the two sidebands.

So? How are the sidebands excluded from "output level" in
my statement which you quote, but change (twice missing out
the word 'level') within your reply text?

Is this your problem, you only see the words you want to?
Then, considering output as being output frequency, rather
than output level, you see an incorrect statement.

Now, going back to my original statement, that output
level (amplitude) "swings" (varies) above and below the
carrier level (the amplitude of the unmodulated carrier)...

Also power meters are not, per se, frequency specific.

I made no mention of readings on a specific meter, just
the actual output. Whatever you read on a meter does
NOT change what the transmitter is actually putting out.

Just like the last time, you appear to be either getting
ahead of yourself or totally changing the topic.
I am still unsure whether you are doing this on purpose,
just for the sake of arguing, or have been snorting something.

The problem is all RF is rectified to a time varying
DC level

What you do with a signal, once you receive it, makes
no difference to what is actually being transmitted.

that corresponds somewhat to the varying amplitudes
of the RF signals being sampled.

What varying amplitudes, you said it doesn't... and
you can prove it by measuring the average.

I really am having a hard time taking you seriously. Not
only do you start ranting about things that have nothing
to do with the issue (also commented on by someone else
on the group), but you then go back on your whole
argument.

I really do have to consider the possibility that you are
simply trying to wind people up and, like the Griffter,
you will say anything that you believe will achieve your
goal.
