I remember diversity reception on HF radio systems a few years ago
using R390A receivers by tying the AGC busses together. While I
now have several acres of property available to me these days, I am
not really interested in getting back into that again.
Is not quite so simple using the current generation of UHF FM
receivers. May be one of the reasons I still have a few of the
slightly earlier generation of UHF FM receivers in the garage?
I can theorize on my approach to the problem though.
Back in the late sixties, I worked for a company whose design
engineer had a slightly modified ARC-5 receiver in his car on the
AM broadcast band using an IF strip with 120-130 dB AGC controlled
dynamic gain. No matter where he drove, the audio output of the
receiver wouldn't change.
In a design he made for that company, the company manufactured
receiver had four channels - each with the basic 120-130 dB AGC
controlled dynamic gain IF.
One of the lurkers on here may remember those days.
One of my file cabinets in my seemingly never ending garage still
has a copy of that IF strip design.
