Greetings Folks,
An "Evasive" noise blanker is on my wish list. This is the system where the
noise blanker receives noise from "out of band" and none of its circuits
(except for its input "tap off" and the IF Gate) are in the main signal
path. Best done when you can tune the noise blanker receiver a little to
avoid strong out of band signals (ie evasive). The result is that your
crosstown "friend" at S9++ and 1 kc up does not "key" the noise blanker. The
idea has been around for a long time, Collins used it but they picked up
noise at low VHF. Bit more complex but it really pays off I've found.
73,
Geoff.
