The noise blanker in my 544 is extremely effective against line noise. I'm
told it would work well with ignition noise, too. But I believe it is not
much punkin' on atmospheric noise. (I have been wrong before).
My Omni-C noise blanker was a poor imitation of the 544 blanker UNTIL I made
its circuitry identical to the latter -- then it worked very well, indeed.
It was an easy, reversible modification to the Omni-C blanker.
I wrote an extremely brilliant analysis of locating sources of line noise.
It used to be online but is no more. I can email it to anybody who is
interested. If anyone can post it and deems it worthy, I'll send it to just
one person. It is a very small file.

Subject: [TenTec] Looking for NB for Triton 544
Thought I'd ask on the off-chance somebody has a noise blanker board
available for the 544...
Love the old 544 but drowning in summertime electrical noise here...much of
it blankable on many radios. Wish the Omni V blanker worked. Usually end up
running an FT-102 lately because of the effective NB.
Maybe I'll get lucky and find one!!
