CB & Single Side Band Radios FAQs

What is a CB Radio?

A CB (or citizens band) radio is a type of two-way communication system that utilizes a shortwave band, allowing for short-distance communication between individuals. Unlike HAM or other personal radio services, CB radios don’t require any special licensing in most countries and can be used for both business and personal use. 

Do I really need a VHF radio?

The short answer is, yes, you most definitely need a VHF radio or 2-way radio particularly if you boat any significant distance from the shore. But, why? If you get into trouble you can simply call the authorities on your cell phone, right? Well…maybe and maybe is not the answer you want in an emergency. The following are the reasons you need a VHF radio on your boat in addition to your cell phone.

Imagine that you find yourself in an emergency situation and you are offshore and away from cell towers. Or maybe you are not that far offshore, but the day is very overcast and your phone is having difficulty obtaining reception. You need to contact the authorities or other support and you look down at your phone and see no or maybe only one of those coveted bars. With VHF radios you never have to worry about losing service. While cell phones rely on cell reception, data, and wifi, two-way radios are a self-contained communications network. This means that if for whatever reason cell phones aren’t working, your two-way radio is there at the ready.

Certain two-way radios are built to withstand very harsh environmental conditions. Rain, sand, extreme cold do nothing to stand in the way of these rugged radios as many two-way radio models are waterproof and sand-proof. Some can be submerged in water for up to 30 minutes, in a depth of three feet, and still be functional.

Multiple people can be dispatched at one time reducing the need to call people individually. In addition, everyone involved in an emergency situation can communicate instantly assuring help is on the way as quickly as possible and all involved can stay in touch in the meantime.

Fixed VHF radios are powered by the boat’s electrical system. However, handheld 2-way radios generally have longer battery lives than your cell phone and serve as great backup communication devices.

What is the typical range of a VHF radio?

With the right technology in place, a two-way radio’s coverage can be extended across a very wide distance – 30+ miles. Obstacles in a radio’s line of sight will block or diminish its signal, but more powerful antennas can substantially extend this distance.

Can VHF radios communicate with telephones? 

Many two-way radios have what’s called a telephony feature, which allows for communication between the radio and a landline, or cell phone. This is possible because radio base repeater stations can be connected to telephone networks. Telephony functions are very helpful if there might be a need to communicate with people who don’t have a two-way radio. This said, emergency and rescue organizations are very used to communicating with two-way radios.

Do VHF radios have a use beyond emergency communication? 

Radio ahead for a berth at a marina or maybe you want to chat with a passing boat for advice on entering a new channel. Do keep in mind, however, marine VHF radios, whether fixed or handheld, may not be used on land – it’s the law. Once a VHF radio goes ashore, it cannot be used for marine band transmission without a Coast Station license. While your marine VHF radio cannot be used onshore, many boaters find 2-way radios not using a marine band transmission – think walkie talkie from your childhood – handy for communicating fairly short distances with friends and family while onshore.

Simply break off the red protective tab and the radio will be immediately ready to turn on to channel 16. For everyday use, ACR offers a lithium polymer rechargeable battery option. The quick-release rapid charger provides the ideal solution for keeping the batteries fully charged.

What is the difference between EPIRB, PLB, and AIS technology?

EPIRB stands for Emergency Position Indicating Radio Beacon. They are used to alert search and rescue services in an emergency. They transmit a 406 MHz distress frequency signal via satellite and earth stations to the nearest rescue coordination center.

The network EPIRBs work on is called Cospas-Sarsat, and it is an international collaboration. It’s up and running 24 hours a day, 365 days per year. In 2021, 263 people have been rescued so far—143 of those people at sea. Worldwide, over 48,000 people have been rescued since 1982.

It is essential for boaters to understand that this network is to be utilized in the case of genuine emergencies, not simply if your boat breaks down and you need a tow.

PLBs work the same way that EPIRBs do— they send a coded message on the same distress frequency and utilize the Cospas-Sarsat network. The most crucial difference is that EPIRBs are registered to a vessel, whereas a PLB is registered to a person. This means that if you switch to a new boat or you decide to use a friend’s boat, the PLB will still be registered to you.

EPIRBS, on the other hand, would need to be reregistered if you buy a new boat. If you rent or use someone else’s boat, you wouldn’t be able to take the EPIRB from your boat. That’s because if you did use it, it would send a distress signal describing a vessel that isn’t yours. So, you will need to rent an EPIRB, which you can do relatively inexpensively from Boats U.S. Foundation and other sources.
