Racine County, Wisconsin (WI) Scanner Frequencies and Radio Frequency Reference (2024)

FAQs

What are the best frequencies to listen to on scanner? ›

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.

RF Picking Systems

An RF scanner is a Radio Frequency Scanner which is a wireless handheld device that uses radio frequency wireless network to communicate with software to transfer information throughout the network.

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.

Most police radios operate in the 700 and 800 MHz UHF bands. These provide pretty good range, especially in urban areas. A squad car radio built into a car could easily give range of 10–25 miles under ideal conditions. A handheld usually will do a couple of miles, anywhere between 2 and 5 miles.

Anyone with a broadcast transmitter can project whatever they want — music, speeches, other communications — for those with scanners to pick up and listen. Generally, scanners are for picking up VHF and UHF transmissions, or Very High Frequency and Ultra High-Frequency transmissions.

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.

The term scanner generally refers to a communications receiver that is primarily intended for monitoring VHF and UHF landmobile radio systems, as opposed to, for instance, a receiver used to monitor international shortwave transmissions, although these may be classified as scanners too.

95.3 WBEV is your hometown station, powered by the Daily Dodge, bringing you breaking news, sports, closings, and more from Dodge County, Wisconsin.

What is the frequency for Midwest radio? ›

A radio frequency (RF) signal refers to a wireless electromagnetic signal used as a form of communication, if one is discussing wireless electronics. Radio waves are a form of electromagnetic radiation with identified radio frequencies that range from 3kHz to 300 GHz.

Try a police scanner website.

The best way to find an online police scanner for a particular city is to search the web for that city and "live police scanner." You can also use any of the following sites to browse police radio channels and listen. Some popular options: Broadcastify (US) OpenMHz (International)

Scanner Radio is one of the best police scanner apps on Android and iOS. The app covers live audio feeds from more than 7,000 fire department and police scanners, weather radio stations, ham radio repeaters, marine radios, and air traffic.

Ideal speaker frequency response would cover the full spectrum of human hearing, i.e., 20 Hz to 20,000 Hz, with a smooth response across this range. However, perfect sound reproduction is difficult due to several factors like speaker design, room acoustics, and human hearing limitations.

Expert-Verified Answer. A frequency of 1.5 MHz is required for a good ultrasound scan, where the wavelength is no more than 1.0 mm. This frequency is within the range of ultrasound and is commonly used in medical imaging applications to produce detailed images by reflecting from surfaces within the body.

In the above-mentioned studies, music was always tuned at 440 Hz. However, the results of a pilot study suggest that music tuned to 432 Hz vs 440 Hz may have better benefits for humans, in terms of heart rate reduction and greater satisfaction after listening (15).

While 20 to 20,000 Hz is considered to be the normal human hearing frequency range, this set of numbers isn't the same for everyone—the frequency range of human hearing can change depending on age, continued exposure to loud noises or other hearing loss risk factors.
