Some of the bands you should find out about include the following: 50-MHz, 144-MHz, 440-(430)MHz, and 1.2-GHz. The most popular is the 144-MHz (2-meter) band. That's where you'll find a lot of ham radio operators as well as local public safety calls.

Ka Band represents the most recent and widely used frequency range in police radar technology, operating between 33.4 to 36.0 GHz. This band is favored by law enforcement for its shorter wavelengths, which allow for more accurate speed measurement and reduced visibility to radar detectors.

Many Ham radios are capable of receiving police, unless the police have encrypted their transmissions. However, most police agencies today are using some sort of digital radio, like VIPER in NC, and some form of DMR in others. You of course can get scanners that cover most police frequencies, but why use a Ham radio?

In addition to decibel levels, harmful sound frequencies can also be damaging to human hearing. Low frequencies (under 20 Hz) and high frequencies (above 20,000 Hz) that humans cannot perceive can also affect the ear and have adverse effects on our health.

No, Baofeng radios are not police scanners. So you decided to sink a couple bucks into a Baofeng just to see what all the hype is about.

In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna.

The Ka-band electromagnetic frequency spectrum ranges from 26.5GHz to 40GHz. In law enforcement or police radar applications, the frequency of Ka-band radar is usually limited between 33.04 GHz and 36 GHz. Ka-band radars are hard to detect, as three different frequencies–33.8 GHz, 34.7 GHz, and 35.5 GHz–are in use.

What K band frequency do police use? ›

Law enforcement authorities adopt the K-band frequency due to its high performance, commonly using 24.125 GHz and 24.15 GHz. Some non-law enforcement applications of K-band frequency are automatic door openers, collision avoidance systems, and blind spot monitoring systems in vehicles.

Police radios are usually narrow FM radios operating in the 150–174 MHz, or 450–470 MHz or 800 MHz bands. Those in the 800 MHz are often trunking repeater systems.. Some are analog and now some are going encrypted digital.

Police radar guns operate on three frequency bands: X band, K band, and Ka band. Most newer guns the police use operate on the super-wide Ka-band. K-band is still quite common, given its historical advantage to Ka-band.
