Frequently Asked Questions
How do I know if my police scanner will work in my area?
Before buying, check if your area is encrypted and what radio system is used. Visit RadioReference.com to look up your county's radio systems. If you see 'E' (encrypted) next to police talkgroups, no scanner will work. Also check if the system is P25, DMR, or analog to ensure your scanner is compatible.
What accessories do I need with a police scanner?
Essential accessories include: a programming cable (USB), antenna upgrade (stock antennas are basic), spare batteries for portables, and external speaker for desktop units. Optional: GPS antenna for location-aware scanning, carrying case, vehicle mount for mobile scanners.
How hard is it to program a police scanner?
Modern scanners offer two approaches: database-driven (enter ZIP code, scanner auto-programs) or manual programming. The BCD436HP and SDS series use the Sentinel software and built-in databases for easy setup. Traditional programming requires knowing your area's frequencies and talkgroups from RadioReference.
Do I need an upgraded antenna?
Yes, for best performance. Stock antennas are designed for portability, not performance. For home use, a discone or wideband base antenna improves reception significantly. For mobile use, a mag-mount or NMO antenna on the vehicle roof is essential for good coverage.
Can I return a scanner if it doesn't work in my area?
Return policies vary by retailer. Amazon typically allows returns within 30 days. However, it's better to verify your area's encryption status and system type before buying. Once you've confirmed your area is unencrypted and know which digital mode is used, you can buy with confidence.
What's the difference between new and refurbished scanners?
Refurbished scanners from manufacturers are typically inspected and repaired to factory standards. They often come with shortened warranties. Given the $400-700 price range of quality scanners, buying new usually makes sense unless the refurb discount is substantial (30%+ off).
If Your Research Shows Encryption...
If your area is encrypted, don't buy a scanner. But you're not powerless. Encryption is a policy choice, and communities are successfully fighting back across the country.
