RE: Strength of signal and 3IM
Gentlemen, as I said, I am no electronics or radio expert. Go read the AMA archives to understand that there was a serious problem with 3 IM during the frequency phase-in in the mid-eighties. Maybe something has changed on the planet that I don't know about. Maybe the newer receivers are so good there is no problem. I know that not all of a 300 member club are using the latest receivers. I don't know how spaced out the glider pilots were in the example above, and I am told the interfering "pairs" need to be within 10 or 20 feet of each other. I know one can always find some anecdotal incident to "prove" any theory. You are not telling me "something I don't want to hear".....I fly mostly PCM receivers and am not very exposed to this problem anyway.
And finally, there was more involved in this "white pin" system than simply minimizing 3 IM.
