[TenTec] Corsair II vs Omni C

[Bwana Bob]

Yes, the Corsair NB is good for narrow impulse noise pulses, but not 
very good at wideband noise like power line noise. On the plus side, it 
does not introduce distortion or intermodulation like other noise 
blankers do.

The NB in my Scout is excellent, and not very complicated.
