How to Listen To Live Radio Communications Online

Find Scanners Around the Globe on "Radio Reference"

Being an addicted -- or maybe I should say enthusiastic -- Search and Rescue volunteer, I like to listen to our county's SAR frequencies to find out what's going on before our team actually gets called out for a mission ... not to mention eavesdrop on what else is happening with law enforcement in the area. In addition to the Sheriff's department radio traffic, I can listen to the action in nearby Grand Canyon National Park and with the Arizona Department of Public Safety, Flagstaff Police, Fire and EMS.

And all of this I can do online while working on my blogs and websites, "tweeting" on Twitter, writing articles such as this, working on my business, or simply staring into space and shmoozing with my dog. The source of these live audio feeds is RadioReference.com.

Radio Reference is "the world's largest radio communication's data provider, featuring a complete frequency database, trunked radio system information and FCC license data." Live audio feeds are available in the United States, Canada, Mexico, Australia, Israel and Chile. Registration and access is free, though there are advanced features available to Premium subscribers. I use the free service, and it's more than enough for me.

Headphones For Your Private Listening Pleasure - Don't bother anyone else with your scanner or CB radio addiction

Well, I should speak for myself. Not that I'm addicted, but I do like to listen in quite a bit, and I don't want to force my habit on anyone else. A pair of comfortable, economical but high-quality headphones is all it takes.

Sennheiser HD 201 Lightweight Over Ear Headphones

The Sennheiser HD201 Stereo Headphones have proven to be an excellent low-priced alternative to high-end studio headphones. With great clarity, the Sennheiser HD201 headphones are the ideal entry into the world of powerful stereo sound. With excellent attenuation of ambient noise, these headphones offer outstanding comfort at an affordable price. The HD201 features stereo-rich sound with crisp bass response. They are lightweight, rugged, and the high-quality leatherette ear pads also make them comfortable to wear.

 

Or Go Wireless - So you can move around more while you listen in

Sony Infrared Wireless Stereo Headphone System
Sony Infrared Wireless Stereo Headphone System

The MDR-IF240RK wireless stereo headphone system features 30mm drive units for deep bass, up to 30 hours of battery life on a single charge, and a transmission range up to 24 feet.

Go Infrared: Infrared transmission works by sending out infrared light signals from the transmitter to the headphones. Infrared signals are resistant to external noise and interference, but the headphones must be within line of sight of the transmitter--the signal can't pass through walls, furniture, or other obstacles.

Understanding What You Hear On The Scanner

Learn the codes

Numeric codes have often been used in radio communication, particularly by law enforcement and in CB transmissions, as replacements for common words or phrases.

Created to help reduce the amount of speech over the radio, the first set of "10-codes" was published by the Association of Public-Safety Communications Officials (APCO) in 1940 and later expanded by the APCO in 1974.

There is, however, no universal set of 10-codes, and their meanings can vary between jurisdictions. This is why, in 2005, the United States Federal Emergency Management Agency (FEMA) began discouraging the use of these and other codes, and the U.S. Department of Homeland Security also plans to do away with 10-codes.

The following is a list of one set of 10-code meanings, which may or may not be identical to all of those used (or that were used, as the case may be) in your area.

A Note About Scanner Codes

Due to new Homeland Security requirements, law enforcement and EMS are moving away from the use of many (actually, most) radio codes and will be using plain text for most radio traffic.

Phonetic Alphabet
Phonetic Alphabet | Source

Learn The Phonetic Alphabet

A is for Adam ... and so on

Over the radio, some letters can sound a lot alike, such as D, E, B and C. This is why the phonetic alphabet was developed. There are two common versions, one for law enforcement and the other for the military. This is the phonetic alphabet used by law enforcement:

A - Adam

B - Boy

C - Charles

D - David

E - Edward

F - Frank

G - George

H - Henry

I - Ida

J - John

K - King

L - Lincoln

M - Mary

N - Nora

O - Ocean

P - Paul

Q - Queen

R - Robert

S - Sam

T - Tom

U - Union

V - Victor

W - William

X - X-ray

Y - Yellow

Z - Zebra

So IF I ever got pulled over by a police officer (which hopefully will never happen), my name would be called in as "David-Edward-Boy-Robert-Adam" and last name, "Lincoln-Adam-Union-Mary-Adam-Nora."

      It is interesting to listen to law enforcement action unfold (and sometimes heartbreaking). When I worked for the National Park Service, we used some 10 code and had a strict radio communication protocol to follow. All of this was driven home on the day one of my colleagues died. Very intense when it's a life and death situation. I can understand why you like to follow the scanner action. It would be extremely helpful as you prepare to enter a search and rescue mission.

      The important thing to remember is from place to place and even from agency to agency that the codes will differ. This is an excellent lens for any scanner buff. I work in a 911 center and love listening to other places on RadioReference and seeing the differences.

      I listen to internet radio foreign countires to becme familiar with their language. People listen to opera, why not scanner traffic. There are those that listen to aircraft traffic via scanners. Each to his own.

      Radio is outstandingly useful in cases of emergency. Most home radio's can be powered from a something like a car battery and use relatively small amounts of power. In an emergency situation a power outage can mean radio is the only reliable means of communication. Cellphones depend on more than just their internal batteries; they also rely on the network of cellphone towers. Trinidad Radio

      Many -approach radio providers require you to purchase a license from the FCC. The CB radio service is not one in all them. The FCC does have some guidelines that you need to observe though. You can find the foundations tucked into the working handbook of your radio. You may also obtain them on the Internet. The foundations are easy to learn and are organized as an inventory of widespread questions. They include technical guidelines about radios and antennas as well as what you'll be able to and might't do on the air.
