Frequency Considerations for Recreational Walkie TalkiesIf you're in the market for walkie talkies for personal use, you have an immediate and important choice to make: What radio frequency band do you require? Frequency! Walkie talkies obviously utilize 'wireless' communication methods so when using a 2 way radio you're transmittnig and sending your message through the air -- the same air that's currently carrying television signals, commercial radio signals, Ham radio signals and literally thousands of signals from other private walkie talkies.
The Federal Communications Commission (FCC) has the job of controlling all of these communication signals so they don't run into each other; to accomplish this they have reserved frqeuency bands for use by certain types of communication (signal sending) devices. There are two frequency bands in use for recreational walkie talkies, these are called Family Radio Service (FRS) and General Mobile Radio Service (GMRS).The FRS band! In 1996, the FCC reserved a set of radio frequencies they called the Family Radio Service (FRS) band, specifically for short-range walkie talkies (radios that operate no more than 2 miles away from each other) with a small power output (up to 500 milliwatts or one-half watt).The GMRS band! About fifty years before the FCC created the FRS band they had reserved a set of frequencies for higher power walkie talkies that operated over a longer range this is the Gneeral Mobile Radio Service (GMRS) band.
The GMRS band is for radios with a power output between one and five watts and a range greater than 2 miles. The FCC regulates walkie talkies that operate on the GMRS band and requires users of this type of radio to obtain a license and pay a fee. The GMRS license is good for five years and costs $80.00; the license must be obtained by an adult (the radios operating under the license may be used by minors but only with the licensed adult's knowledge and permission).When purchasing walkie talkies, your choice is between a set of radios that operates only on one of these frequency bands or a set of radios that's able to operate on either one of these frequency badns. This determination will obviously have to be made based on the maximum distance the radio users will be from each ohter. If the radios are to be used within two miles of each other, FRS will be the hottest (and least expensive) choice.
If a greater distance is consistently required, walkie talkies that operate on the GMRS frequency band will be required. If the need for distance is uncertain or if you want the option of occaisonally transmitting up to five miles a FRS/GMRS hybrid is the radio set to choose.Http://twowayradioshq.Com Find out more about Two Way Radios.
