Different Radio Services

The following are your options when it comes to radio services available to the general public. I include this because I am very tired of answering the questions of
1) How can I talk to my family/friends/someone in in an emergency? (Short answer: You probably won't be able to unless they are prepared to hear you.)
2) What radio should I buy? (Ask an easy question like, What's the best restaurant or Who's the best movie star? Short answer: It depends. What do you want to do and how much are you willing to spend?)

Family Radio Service (FRS)
This is an unlicensed UHF FM handheld service (FCC description). These are the bubble-wrap radios you can buy at Walmart or on Amazon. Range 1-2 miles at most.

General Mobile Radio Service (GMRS)
The General Mobile Radio Service (GMRS) is a licensed radio service that uses channels around 462 MHz and 467 MHz. The most common use of GMRS channels is for short-distance, two-way voice communication using hand-held radios, mobile radios and repeater systems. (FCC description) There are many sources for radios so Google GMRS radios.
Here is a short video about how to apply for a GMRS license.

Citizens Band (CB)
The Citizens Band Radio Service (CBRS) is a unlicensed, private, two-way, short-distance voice communications service for personal or business activities of the general public. It also may be used for voice paging. It is authorized 40 channels between 26.965 MHz and 27.405 MHz. (FCC Description) There are many sources for radios so Google CB radios.

Multi-Use Radio Service (MURS)
The Multi-Use Radio Service (MURS) uses channels in the 151 – 154 MHz spectrum range with no license required. The most common use of MURS channels is for short-distance, two-way communications using small, portable hand-held radios that function like walkie-talkies. (FCC description) There are many sources for radios so Google MURS radios.

Amateur Radio Service
The amateur and amateur-satellite services are for qualified persons of any age who are interested in radio technique solely with a personal aim and without pecuniary interest. These services present an opportunity for self-training, intercommunication, and technical investigations. Twenty-nine small frequency bands throughout the spectrum are allocated to this service internationally. Some 1,300 digital, analog, pulse, and spread-spectrum emission types may be transmitted. A license is required to transmit. There are three license classes: Technician, General and Amateur Extra, each which has its own exam. (FCC Description) There are many sources for radios so Google Amateur Radios so you see your options. Ham Radio Outlet and DX Engineering are the best known retail names for Amateur Radio equipment.

Your First Amateur Radio

This is for the New Amateur Licensee. Typically, you have just received your Technician license. If you don't have a mentor (called an Elmer in Amateur Radio language) who is giving you his cast off radio*, then you have to decide on what radio you're going to buy.

The first radio is most often a handheld radio, called an HT in Amateur Radio. (Note: NEVER call it a walkie-talkie - that's an FRS radio.) They are self contained with the radio, battery and antenna all contained in one convenient package. At the present time, the most common entry level HT radio is a Baofeng UV-5R going for as little as $17. There are HTs which are more expensive with more features - longer lasting batteries, more radiated power, more memory storage, easier programming, etc. The old joke is true - you can have better, cheaper, or faster - pick any two.
I don't recommend any particular radio - you have to make your selection depending on how you will use the radio, what capabilities you will need or want, and how much you want or are able to spend. Any radio sold today will be a functional radio - that's market driven. I use Baofeng UV-82s (I have four) as my HT because a Baofeng UV-82 was my first radio, given to me by my son. It's still a functional radio after 7 years and after being run over with my truck (the battery tends to fall out), They do everything I need a HT to do and if anything happens to one, I'm not out a lot of money.

If you want to upgrade, I recommend starting with a better antenna. The typical antenna that comes with a HT is called a rubber ducky and is usually very inefficient. After market antennas available in many forms, sizes and prices. Do your research and ask other operators what they recommend. My first HT came with a telescoping whip antenna, so my upgrade was to build a copper pipe J-Pole antenna which I clamped to the corner of my patio and had a coax cable and adapter to connect to my Baofeng. Because the antenna had some gain and was higher, I had much better reception and I could be heard further and clearer.

My next upgrade was to upgrade to a mobile radio. Designed to be installed in a vehicle or a go-box, these radios need a power supply and an external antenna. The power supply can be a battery or a plug-in-the-wall power supply. The external antenna can be anything from a simple dipole, mag mount antenna on a cookie sheet, or a vertical on a mast or tower. You will need coax to connect the radio to the antenna. With this setup you will have more reach because you are operating with more power and a much improved antenna.

At this point, the sky is the limit! There are many options for improving your operating experience from microphones, headsets, amplifiers, SWR meters, different modes, sound cards, not to mention activities such as ragchewing, contesting, DXing and emergency communications.

*This can be both good and bad. It's good because you don't have to spend money. It's bad because it sorta locks you into whatever the said radio is capable of. Also, A WARNING - your first radio becomes the de facto radio you will use forever, if you turn in on. ARRL claims that 90% of all Amateur Radio licensees NEVER turn on a radio and use the Push-To-Talk button. And you may have to buy a power supply, coax and an antenna.
