Yeah, it's been all too many years, but hard limiters were not used in many designs and no FM detector is completely immune to noise.
It brings back memories of just how loud and strong ignition impulse noise used to be back in the 50's before anyone did anything to suppress it! Used to roar through on 2 meter AM in the home station from cars hundreds of yards away at times! I was kidding about Motorola/ Working in land mobile with E.F. Johnson equipment, "Motorola" was always in our sights ;-) We did very well in the San Francisco area because we did have superior repeater sites. The Motorola gear was very good stuff as was the E.F. Johnson.

I remember when GE had it in their radio, and we didn't, it soon showed up so we could compete in bids. I imagine the bid process drove that more than any actual need :-) 73, Bob N6WG _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
