The noise blanker is the Ten Tec Scout is excellent. It is a simple 
circuit which should be easy to duplicate.

The hardware optional NB for the Eagle does eliminate the pulse 
ignition/injector noise in my truck mobile and it does not punch holes

 The only noise blanker I ever found to help things was the one on the 
Drake R4C.

 Do any of these TT noise blankers do anything for you guys. Mine 
appears to do very little in my Omni VI  Plus...

 Of my two Corsair II's, one has a NB board p/n 80977, which 
correspond to the NB called out in the manual. The other Corsair II 
has a NB board p/n 81401, for which I've not been able to find any 
documentation. TenTec has been unable 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.
