What CB channel should I use?
Any authorized CB radio frequency is open to all, but some have agreed-upon special purposes.
For instance, channel 9 is for emergency use, and channel 19 is used by truckers to report on traffic conditions.
Channel 19 is at the middle of the bands, thus has the best antenna efficiency.
Can you use a CB radio as a police scanner?
From the manufacturer. The BearTracker 885 does what no other CB Radio can do: It can keep you up-to-date with current public safety activity anywhere in the US and Canada* by scanning for police, fire, ambulance, and/or DOT radio traffic. No need to worry about changing scanner programming as you drive.
Is CB AM or FM?
Civilian and military aircraft use AM (military can be found using FM at times). CB mostly uses AM and amateur radio uses many different modes with FM being the most widely used mode above 30 MHz.
Do you need a Licence for CB radio?
CB is covered under Part 95 of the FCC rules. A CB radio does not require a license to operate. For the most part, you can operate a CB radio on all 40 channels and frequencies designated by the FCC for CB, but there are some caveats. First, you can use CB only on those 40 channels and frequencies.
