Police scanner software allows you to program your scanner radio from your computer (for PCs only, sorry, no Mac software is available). Butel ARC (Advanced Radio Control) software that is available for most scanner radios is two variations: Basic (for programming only) and Advanced (which also allows for control of the scanner from the computer along with logging and recording - check specs for details). This police scanner software is also available either on CD-ROM or as a download from our web site, allowing you to receive the software instantly upon ordering and saving postage costs. Some scanners do come with very basic or sample software at no charge but the ARC software provides far more capability and features including the ability to download frequency/trunking/text tag information direct from RadioReference saving countless hours in programming (a subscription to the site is required and is available through BuTel). Get the most out of your scanner and have a lot of fun doing it with police scanner software.
