Well if you want a relative (SO2R) novice's perspective, my tolerance is
probably about the same as would be the case in a co-channel single radio
situation, i.e good old fashioned QRM! I find it difficult to objectively
estimate what level this might be however.
It *should* be better inasmuch as one has spatial diversity( i.e. left
ear/right ear) in one's favour, but I suspect this is not helping me much
yet. Ask me in another 25 years or so, although you might have to QSY to
another place to raise me!
What I do find somewhat helpful is to introduce some audio frequency
diversity. i.e set the pitch on the left radio at about ( say) 600Hz and
that on the right radio to (say) 800Hz, simulating what one might hear
randomly in a single rx bandpass. However this doesn't always, or
often,work as callers don't always perch where you would wish, still we
need all the help we can get to aid this fiendish practice!
