I agree. The NB on the Triton's completely eliminates my S9+ powerline noise, 
but neither the Corsair or OMNI V NB's are effective dealing with that noise. I 
too have wondered why the Triton NB design was abandoned. I can only guess that 
perhaps, at the time, the Soviet's OTH woodpecker presented more of an 
aggravation than impulse/ignition noise to op's. I didn't have any TT gear 
during the reign of the woodpecker, but none of my other radios dealt with it 
effectively. The way things are going, maybe the variable pulsewidth NB's of 
the Corsairs and OMNI V that were designed to defeat the woodpecker, will be 
useful again.

  The best noise blanker I've ever heard was in the Triton 544. It really works 
very well . Why anyone would change a good design is a mystery.

to find documentation for this NB, despite the fact that it appears to be of 
production quality (not one-off lab bench quality). Does anyone else have a 
Corsair II with the 81401 NB, or any information (schem and interface 
interconnect) for this NB? The 81401 NB has roughly 2/3 the component count of 
the 80977, and has no unpopulated holes or device hole patterns. S/N of the 
Corsair II with the "rogue" NB is 561-02258.
