Jim, that information is incorrect. The K3 NB can not possibly have
any impact on the P3 or P3SVGA as the IF pick-off is at the output
of the first mixer - *before* any noise blanker gate.
Joe,
I've never studied the schematic or signal flow in the regard, but I
often study the screen of my P3, which DOES show reduction of noise when
the wider NB is active. 2-4 dB is typical for the types of noise for
which it is effective.
I appreciate the alert to the existence of the P3 NB. I last updated
firmware about six months ago, and it was not in that version. It does,
indeed, work pretty well.
