police-scaneresThere was a time when only enthusiasts with a citizen’s band (CB) radios could tuned in to listen to special radio frequencies of emergency services such as police, firefighters, paramedics and medical technicians. Investing in a police scanner was very expensive, not to mention illegal in some places.

However, an ordinary citizen listening in to police communicate over their special wireless frequencies is perfectly legal in most states in the USA, and this applies the same to almost every country all over the world. As long as you don’t interfere with the transmissions, you are safe to tune in.

Most public services and first responder emergency services operate on low frequency radio waves to communicate with one another, and these can be intercepted without much difficulty with standard radio scanners by tuning into the right frequency. As of today, the scanners can not only listen in on police or fire personnel’s communications, but they can also receive weather and local airport traffic communications.

As cellular technology has progressed significantly, and with the advent of Internet, it has indeed become much easier to intercept cellular communications. Nevertheless, it is a federal crime to spy in on private cellular phone calls; it is a different matter altogether if the government is involved in the spying though. Most law enforcement agencies avoid radio communication and use cellular phones for this reason alone.

You might be wondering, “Why would I be fascinated to tune in to a live police radio streams?” The answer is multi-fold. You might be curious to know what is going on in your surrounding area, or you might want to keep yourself updated about weather forecasts or current events, or perhaps you just want to make sure that your loved ones who work in law enforcement services are fine. If you are a journalist, you might be tuning in to keep abreast of breaking news. Whatever be may the case, there are a lot of reasons to tune into radio frequencies.
