Hi Kevin,
Your information about the Omni-C blanker was not true for mine. I have a
Triton 544 and an Omni-C, each with the proper Ten-Tec blanker. The 544's
blanker would quieten the loudest of line noises. The Omni-C blanker was as
good as a brick in the corner would have been.
I examined both schematics and noted the differences, then modified the
Omni-C blanker's circuitry to correspond electrically with that for the 544.
As I recall, it was a matter of rewiring just a bit but I think no parts
were required... or left over, either. That was a number of years ago.
My Omni-C blanker thereafter was as good as, but not better than that in the
544.
73 and Good Luck - and Merry Christmas
Mike N4NT

Subject: [TenTec] Old Omni A series B Noise Blanker Question
I'm wondering if anyone's willing to help me with a noise blanker
issue...
I have an old Omni A Series B with the optional factory built model 248
noise blanker installed. I also have a Triton IV Digital with the model
249 noise blanker installed. *The Triton IV's NB works VERY well on my
noise problem* The
Omni A NB does NOT work at all on 95% of any noise I hear...
( I did discover one day that the Omni A NB WILL cut some sort of ignition
noise coming from vehicles passing by on the street!!!)
1) Could you shed light on the rumor I've heard :" Yes; the Omni C has a
much
improved noise blanker compared to the Omni series A and B" ?
2) Could you suggest modifications to the Omni A's NB to make it
more/exactly
like the NB of the Triton IV?? (I'm aware of a few custom made parts no
longer available from TenTec that I could have used)
3) Is there another NB solution/option in your opinion? ( It just 'ain't'
feasible/desirable to use a "sense antenna in-phase device here,,,)
Any off-list responses to kelectron93@yahoo.com
Thanks & 73,
Kevin WA4GQG
