Mostly we use ham radio to form friendships over the air or through participation in one of more than 2000 Amateur Radio clubs throughout the country. There are over 600,000 radio amateurs in the United States and over 2,000,000 worldwide.

FM radio uses frequency modulation, of course. The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum.

Radio waves are very widely used in modern technology for fixed and mobile radio communication, broadcasting, radar and radio navigation systems, communications satellites, wireless computer networks and many other applications.

In fact, you'll find some truck drivers who use CB radio to communicate when they are in a certain part of the country. For the most part, CB radios remain in use because they are the norm for truckers who have been working in the industry for the last 10 or 20+ years.

They are illegal to use in the US. It pretty easy to spot freebanders(export radio users) because they use voice on the CW( morse) portion of the 10 meter band(Ham).

Radio Frequency (RF) technology is critical to many aspects of modern Electronics. This is because RF engineering is incorporated into almost everything that transmits or receives a radio wave across the whole of the RF spectrum (3 KHz to 300 GHz), including mobile phones, radios and Wi-Fi.

A DECISION to make some UHF radios illegal from June this year has been reversed. The Australian Communications and Media Authority (ACMA) had originally announced that due to fears of congestion the use of 40 channel UHF radios, or citizens band (CB) radios, would no longer be permitted from June 2017.

In some ways ham radio is thriving - more people than ever have licenses and the bands are generally active (although propagation now is really awful). DX'ers are still around and seem to be as active as ever. ... Hams often go to gatherings called hamfests where equipment - new and used - is sold.

VHF- Very High Frequency Very high frequency is commonly used for FM radio broadcast, two-way land mobile radio systems, long-range data communication, and marine communications, just to name a few. VHF includes radio waves from 30 MHz to 300 MHz.

5.0 out of 5 stars Great radio, and Ham friendly support, free CPS to program them. I bought my Hytera radios from Gigaparts, and they are of superb quality. The audio in and out of them is fantastic, and if you don't like it, it has equalizer settings in CPS to change it.

These services began in 1945 to permit citizens a radio band for personal communication (e.g., radio-controlled model airplanes and family and business communications). In 1948, the original CB radios were designed for operation on the 460–470 MHz UHF band.

GMRS is for people that want to use radios to communicate with each other. Ham is for the people that want to send and receive radio signals for the shear joy of seeing if they can. They each require separate licenses.

GMRS is UHF High band FM modulation. Better coverage overall in any of the UHF bands. CB is good for mobile to mobile talking ( I mean car to car). There also is a limitation on the amount of WATTS you can legally crank out of it.

Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band is also used.

In December 2006, CB radio was deregulated by Ofcom and it is now licence-free. Although the use of CB radios in the UK has declined from its peak, it is still popular, especially with the farming community, Land Rover owners and Mini-Cab services.

Despite the emergence of the transistor, vacuum tubes aren't completely extinct, and they remain useful in a handful of niche applications. For example, vacuum tubes are still used in high power RF transmitters, as they can generate more power than modern semiconductor equivalents.

This radio can be programmed to receive on any frequency in the typical VHF/UHF land mobile bands. It cannot be used legally used to transmit on either FRS or GMRS frequencies because the radio is not Part 95 certified. There are no frequencies in this radio that can legally be used without a license.
