Some signals actually bounce of the earth's atmosphere and can travel thousands of miles. Generally, expect the scanner to receive signals from a 25- to 50-mile radius from your location.
scanners are perfectly legal to listen to anywhere as long as the information gathered isn't used..
These scanners are obsolete primarily due to the fact that over the past few years, more and more public safety agencies have been transitioning towards operating on trunked and digital radio systems making some of these older analog scanners obsolete.
But, the vast majority of US police agencies still operate on radio channels compatible with the little $30 technological wonders. The programmable portables are sold for use by amateur radio, HAM operators for use on their two-meter and 70-centimeter bands, which are adjacent to the public safety bands.
Essentially, squelch is a specialized type of noise gate designed to suppress weak signals. Squelch is used in two-way radios and VHF/UHF radio scanners to eliminate the sound of noise when the radio is not receiving a desired transmitter.
Feed Provider Since 2012. Others in your area may have a DMR radio or scanner and may be monitoring this system. They would know if it is encrypted or not. You could try asking in your state forum or click on the red and white triangle in the upper right hand corner and ask that this thread be moved.
The police are not on any channel on any 'walkie - talkie'. There are radios available that can allow you to hear some or all of the public services (police, fire, EMS, etc.) on the airwaves near you.
(Public Service Through Communications ), the organization that started monitoring CB channel 9 in the US in 1962, still exists, but membership is sparse, with few monitoring teams in existence. The most successful ones use more than just CB radios, and don't actively monitor channel 9, because it's seldom used.
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.
Can I monitor encrypted signals? No. This is illegal & no police scanner (that the public can access) can monitor encrypted channels.
In the U.S., it’s perfectly legal to intercept publicly-available police broadcasts. As the Radio Television Digital News Association has noted, the law around rebroadcasting those communications is a little murkier, but arguably protected by the Constitution.
While police officers may use many of the same brands available to the public, such as Motorola, Kenwood, Retevis, and Maxon, the main difference of police radios is the type of frequency that they operate on. An example would be the high power Retevis RT1 seen to the right, which can be purchased by civilians.
Officially, the FCC states that you cannot listen to private phone conversations. But you won't need to worry about the legality of it, because of the impossibility of it. After the FCC but this motion into effect, so began the banning of scanners that could pick up cell frequencies, and the story goes on from there.

2 way radios are difficult to trace. Two-way radios, also known as walkie-talkies, remain popular even after the advent of cell phones. Police and security forces, the armed forces, event managers, hunters and many others use them. Two-way radios are extremely difficult to trace.
Your signal can be tracked. It's known as DF (Direction Finding) in the amateur radio world. Hams have made a sport of it which is called Fox Hunting. When it comes to an Amateur Radio license in the US, yes you can be tracked by that since it's public record.
SUMMARY: The United States Coast Guard is announcing that it will no longer maintain a watch on 2182 kHz, will no longer guard the Digital Selective Calling (DSC) channel 2187.5 kHz, and will no longer transmit Marine Information Broadcasts on 2670 kHz.
A trunked radio system is a digital two-way radio system that uses a digital control channel to automatically assign frequency channels to groups of users. A trunked radio system is an advanced alternative in which the channel selection process is done automatically.
You cannot use it to communicate with any standard walkie talkies, whether they use CB, FRS, GMRS, or MURS. To sum it up, it has to be MURS Part 95 certified or be grandfathered in, of which the Baofeng is neither. Of course CB uses way different frequencies but I'll tell why it isn't legal, in case it helps someone.
Cell phone calls are encrypted on the air link - you CANNOT hear them with any regular scanner. 3/4G and LTE calls are VOIP calls and are purely data calls anyway - so as well as being encrypted, they are just random data flying through the air and impossible to intercept without very sophisticated equipment.
Many systems still use conventional FM transmissions for most traffic; others are trunked analog or digital systems. A minority of other police radio systems, the largest examples being the Milwaukee Police Department and Pennsylvania State Police use the incompatible OpenSky format.
Still, just about every state makes it legal to own a police scanner radio. So you may be allowed to legally listen in on the police. Other states like California, Michigan, New Jersey, Oklahoma, Vermont, Virginia, and West Virginia allow mobile scanners, but make it illegal to use them in the commission of a crime.
Analog: Smaller agencies may still be using analog, so an analog scanner might be okay for your needs. Digital: If you get more into it, you'll want to upgrade to a digital scanner because most digital scanners can pick up both analog and digital signals.
