[TenTec] RF Speech Processor "TX IMD"

[Rick - DJ0IP / NJ0IP]

Bob,

You were measuring a good transceiver with a good and properly tuned amp.

You should take a look at the combination FT-450 / ALS-500.
There is nothing for the op to tune, except the mic gain.

You're in for a shock, regardless of where you set the mic gain.
YOU CAN'T BLAME THIS ON THE OPERATOR!

Guys, I maintain there are a lot less lids and a lot more bad radios then
you think!

A technically clean radio meeting today's technical standards and one that
is adjusted and operated correctly and it being used in front of an amp,
again one that is clean and adjusted properly is absolutely no problem. 
There are some import amps on the market that are largely "garbage
generators"  spectrum wise.

My measurements of my radio of the 3rd, 5th and 9th order signals and then
feeding same to my amp, I find that the 3rd, 5th and 9th order signals are
the same value or less in dB below the fundamental output.  I've conducted
two tone tests with both the stand-a-lone radio and then the same with the
amplifier with no issues of concern or any values not consistent with
current technical standards.
