Back in the day with crystal and early programmable scanners, you learned what the frequency was, and you learned it fast. There were no alphatags etc. With todays radios and database programming, you dont learn that stuff anymore. My mind is full of frequencies from 35, 40 years ago I can ramble off at the drop of a hat. And it was useful info when out trackside (railfanning) and a fellow fan doesnt know the freq of the road channel. Scanning aint the same, and neither are the folks using em. Its become to easy to just run to the internet and find what yer lookin for. Every radio has a lower and a upper search range, thats how we found stuff back in the day.
