With todays memory avail, in a basic radio, who needs extra now [Yes, some of us do]
The more you scan, the more you miss.
Its bad enough the processors in scanners are so slow, many areas, like Las Vegas, now have to contend with really large trunked radio systems.
Trunked systems pause the scanner long enough to search through all radio sites and talkgroups. If the trunked system is huge, like the Nevada Statewide Radio System (NSRS) or Southern Nevada Area Comm Council (SNACC), each of those systems can take a full minute to scan with a BCD436HP. A lot can happen in those two minutes. Now factor in all of the casinos and resorts you might want to listen to that have gone to trunking, thats another minute or two. Want to listen to Nellis AFB? Creech and NNSS are also on that system, thats another minute.
These things add up. Im currently running 3 scanners and its no where near enough to scan Las Vegas or the neighboring communities Boulder City, Henderson, and Lake Mead.
