When I lived in Atlanta in the 80's I was a few miles from the local 10m
repeater, and quickly noticed that distant stations which were fading on the
repeater input had climbing signal strength at my location if I switched to the
input. About the time they started getting ratty at my place, I could switch
back to the repeater output, and they were solid there.
I think, on 10m, voting receivers separated by a few miles could actually be of
greater help for maintaining communications with distant stations than for
local mobiles.

Subject: [Repeater-Builder] Diversity FM reception
Paul,
I use double or even triple diversity on 10m & 6m FM.
On 10m, I use a base-fed half-wave vertical installed right above & on the
same mast as a 3-ele horizontally polarized 10m beam. That gives me rather
more polarization than space diversity but it works FB.
I have a 3rd identical rx as well, feed that with an HF longwire & ATU.
One in a while, I get 2 different QSO's from the two rx's! What with FM rx
capture effect (typically 6-8 dB), if one signal is 6-8 dB stronger on one
receiver & another sig is 6-8 dB stronger on the other rx, that's what
happens...
