CB or Citizens Band is not used by police. CB is an unlicensed mobile radio set up, mostly used by truckers. The frequencies of police radios are not universal to all departments, although they are in the same general segment of bandwidth. The police do not use CB radios- never have.
Channel 19Channel usage Channel 19 is the most commonly-used channel by truck drivers on highways, to the point that some radios even have a dedicated button to bring up channel 19 instantly. In many areas of the US, other channels have been used in the past for similar purposes including 10, 17, and 21.

23 channel CB is not illegal to use, only to sell. This was back in the late 1970s when CB grew at such a rate that the FCC added channels. The FCC mandated that all CBs manufactured and sold after such a date be 40 channel.
Can a CB radio be traced? Not hard to do, since all you need is a CB. And yes, the FCC can track where a CB is transmitting from, Heck, they can even tell what kind it is etc.
If you have it turned up loud enough and police (or anyone else who might tell them) are close enough, then yeah, they can tell. I run a scanner in my car. The only way they'd know is if it was picking up a broadcast as they were walking by my car.
Originally Answered: Is CB radio AM or FM? It is AM.
1.1 Citizens' Band ('CB') radio operates in the 27 MHz band. It is a short-range radio service for both hobby and business use. It is designed to be used without the need for technical qualifications. However, its use must not cause interference to other radio users.
Channel 9Channel 9 is the universal CB emergency channel. In most areas, it is monitored by local law enforcement at all times, so please keep random chatter off this channel. Channels 17 and 19 are commonly used channels by truck drivers. 19 is often used by drivers going east or west, 17 by drivers going north or south.
27.185 MHzMost truckers use the unofficial channel 19 (27.185 MHz) to communicate. This channel offers highway traffic information from truckers and other drivers. You'll find a lot of aimless chatter along with the useful information on channel 19.
Since a trunking system might send its call and response on different frequencies, a "Trunking" or "Trunk-tracking" scanner is needed. These scanners will let you monitor the control channel frequency as part of the TalkGroup so you can hear both calls and responses and more easily follow conversations.
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.
CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication, however, various radio propagation conditions may intermittently allow communication over much greater distances.
To prevent interference, CB radio transmissions in the US are limited by the FCC to 4 watts for AM and 12 watts for SSB. You are also required to use a device that is approved by the FCC and you cannot modify it. Other countries have similar rules. Originally Answered: Why are CB amplifiers illegal?

It is authorized 40 channels between 26.965 MHz and 27.405 MHz. Similar service includes the General Mobile Radio Service (GMRS). The CB Service provides a service for short-distance communications by individuals and businesses.

The FCC has approved the use of FM transmission in CB radios. Virtually every CB (Citizen's Band) radio transmits in AM.
2.2 Digital Trunked Radio Systems (DTRS) are two-way mobile radio systems that consist of multiple-channel repeater stations and their control stations, serving a number of base and mobile terminals. DTRS also have roaming capabilities and permit Direct Mode Operation between mobile terminals.
Scanner 911 is a fairly decent police scanner app. It offers up stations for police, fire, and EMS scanners around the United States. Stations are sorted by distance. The app is completely free to download.
While listening to radio bands on police scanners is legal in the U.S., there are 2 types of restrictions. Use of a police scanner while driving* Use of a police scanner in the furtherance of a crime*
CB radios are not capable of operating on authorized amateur radio frequencies and “ham” amatuer radio operators are prohibited from transmitting on the CB frequencies except in an emergency where no other method of communication is available.
Although the commission has eliminated many citizens band rules, such as the requirement that CB operators be licensed, it still strictly enforces the ban on so-called linear amplifiers, which can increase the power of a CB signal from the authorized 4 watts to several hundred watts.
Transmitter power is limited to 4 watts in the US and the EU. CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication, however, various radio propagation conditions may intermittently allow communication over much greater distances.

Though the characters debuted fairly close together and in an era when "Martha" was a more common name, Superman's adoptive mother was not named until years after his first appearance. As noted in another answer, it was 1951 before her name became "Martha", having previously been "Mary" and "Sarah".
