[Milsurplus] Noise question, not too far off topic.

[Glen Zook]

Motorola made a noise blanker which was included in some of their low band (30 MHz to 50 MHz) Motrac units.  This was called an "Extender".  I have known a few amateur radio operators who have adapted that circuit to amateur radio equipment.
