For $5 the Scanner Radio application available at Blackberry App World is cheap fun! It allows you to listen in to over 2,500 police and fire scanners, railroad communications, and weather radio broadcasts from around the world using your BlackBerry®.
A lot of the radio dialog uses 10 codes, a kind of shorthand you’ve likely heard used on TV shows involving police or fire. A reference to the meanings of these 10 codes can be found at the link here.
Here in Orange County, we’re able to pick up the Orange County Fire radio calls countywide. Unfortunately, police and CHP calls aren’t possible since those are encrypted channels.
The app has a free 7 day trial, so no reason not to give it a try. To get a sense of what will be available to you on your BlackBerry®, head over to Radio Reference and listen in to those channels that interest you. Both the app and the online Radio Reference site are a great way to get a taste of radio scanning without the expense of actually buying a scanner!
