Frankly, I think the scanners today suffer from one, big, problem in the design and development....: they are designed by computer people, not public service people or buffs. The computer "geeks" cram as much "tech" into the radio, and then say, "Hey, look what we made!," but don't listen when the ultimate users say, "Yeah, so how are we supposed to use it all if we're not sitting at home in a controlled atmosphere?"
They give you all the "bells and whistles" for a radio, but God Forbid you have to deal with any of those things while driving a car or standing in a dark street. Not only is it impossible, it's down-right dangerous!
Someday, a Uniden-type company will take an old design, like even the 105, and make the guts into a P252 radio, with the ability to assign TGs to a multi-position KNOB (and NOT an up/down push button). To be able to reach over to a radio like the 105 while driving, and turning the knob three "clicks" to a TG you want (without having to pull the car over and putting on your reading glasses!), would be, in my opinion a GREAT development!
I even had one of those 24-channel crystal radios. Despite it's number, I found that putting a busy channel in one position (or even the #1 position) allowed me to find a channel that I wanted while on the road. You would put the constantly-talking weather channel in, say, position one, and you would know that Bronx Fire was,say, four "clicks" from the weather.
I think they are trying to re-invent the wheel.....
