Noise blankers come in two flavors:
1) Hardware noise blankers
2) Software (DSP) noise blankers
The older radios (OM6 and earlier) all had hardware blankers.
So does the Eagle.
The Omni VII and Orion have DSP noise blankers.
It is my understanding that the software blanker can potentially be
implemented to work as well as the old hardware blankers, but in most
radios, most of the OEMs did not do a good enough job of implementing it.
I believe all of the Japanese OEMs and even Ten-Tec and Elecraft got it
wrong, initially.
It was Rob (again) whose persistence in flagging this issue to the two
American vendors, got them to re-think their NB and fix it. I believe it
was similar with FLEX but as I said, I'm getting old and don't recall if Rob
was involved there or not. I think he said he told Gerald.
Unfortunately the Japanese OEMs don't listen to Rob as much as our US OEMs
do.
They don't seem to want to listen to anyone in the field.
It took Yaesu nearly 10 years to implement W8JI's $3 fix to their CW keying
issue that Bob was referring to.
Their FT-1000s polluted our ham bands for 10 years. Eventually most of the
ones in the field got updated (privately), not by Yaesu.
It will be a tragedy if Ten-Tec goes under. They have had an excellent
track record of listening to field input.

REF: Noise and noise blankers
I have a Triton IV with the noise blanker. It takes out pulse noise and
also eliminated static electricity noise from my vertical antenna during
stormy weather last week.
For atmospheric noise, and a neighbor's TV set noise, I use the ANC-4 Noise
Reducer by Timewave. It was recommended to me by another TenTec owner and
it works great (I have a small outside antenna to pick up noise). I have
had many QSOs with the ANC-4 "on" that I would not have been able to without
it.
Hope my experience will help others with similar problems.
