I find it too distracting to listen to more than one radio at a time. What I do is carefully tailor my Fav Lists so I have as little chaff to scan as possible. That way I can monitor my local 911 stuff as well as 8 neighboring counties and still have a fairly short scan cycle. Granted if things are busy it may take a little while to complete the cycle, but if things are quiet the radio can churn through that scan list in about 10-15 seconds. It's true I'll miss things, but when something big is going on I'll catch up to it pretty quick. Excited or stressed voices, sirens, fast talking, these things will catch my attention very quickly even if I'm reading or doing something else at the time. I also have been listening long enough that I usually know who I'm listening to without looking at the scanner. Each system has a different sound to it, even the digital ones to a degree, but also the codes used can be a clue, and I can recognize many of the dispatcher's voices too. It's what works for me.
