I'm not very technical by any means but I know what i like and don't like when it comes to scanners and am/fm/shortwave radios. A biggie for me is speakers.... when I pay $100 or more for a scanner or radio I expect good sound. I have a pro 94 and while the speaker is not horrible it's not that good either. Any radio or scanner can have bells and whistles out the ying yang but if the sounds not too good ...well it kind of lessens the fun of having it.. I like the scanner though. Lights: I bought a Pro 92 for and older fella out the road.... what is up with the light not made to come on when the scanner picks up a freq.? Maybe I missed it in the book.... I'll have to go back over to the guys house and reread the book. Of course you can turn the light on manually. I think seeing and hearing what's on the scanner is a priority. The sound from my Pro -89 and Pro 2054 suit me.
