Understanding what you can do with two way radios

Radio gives you lots of alternative ways to communicate.

Connect with people

Primary use of two way radios is to connect people so that they can talk to each other. These two-way radios connect people together when they talk business, participate in recreational activities, or need to communicate in emergencies.

People on the go, whether they’re just roaming around a mall or driving through the Alps Mountains, may find that a two way radio does a better job at facilitating communication at much lower cost than popular devices such as mobile phones and internet.

Emergency

Radio proves really useful when other means of communications are down (mobile phones and Internet systems). This lack of service can last for many hours or even days during disasters. In times such emergencies like earthquake, tornado or hurricane, having a radio can literally be a lifesaver.

If you’re stuck on the road between cell towers, a Citizens Band (CB) radio is nice to have if you need to call for help. Marine radio, Citizens Band, amateur (or ham) radio are the services that have designated channels or common frequencies where help can be available just at a push of button.

Fun

Keeping an ear on the local public safety action is the most popular use of a special radio receiver, commonly known as a scanner. Scanning the airwaves has become quite popular. You can follow the activities of your local public safety agencies, monitor business users, and listen in at sporting events just by punching a few buttons.

Even when you’re not transmitting yourself, you can have hours of enjoyment just listening to the public safety services around town with a scanner or pulling in the morning news from halfway around the globe on a shortwave radio.
Auto racing fans use scanners to listen in to their favorite drivers talk with their pit crews. Hikers, campers, and recreational vehicle (RV) users often use radios to keep in touch with others and as safety aids. Hang gliders and hot air balloonists can often be heard coordinating their flights with handheld radios.

Special note: After passing the required test and receiving FCC license, ham radios can be used for various activities including public service, and even operating radios in foreign countries.

Work 

When you begin using radios for business, you must abide by certain rules regarding which radios and channels are available.
Public safety and service workers, such as fire and police officers, pilots, paramedics, and transportation and wildlife officers, all make use of radio on a daily basis. Pilots, air-traffic controllers, and airport managers all engage in an intricate choreography that ensures our safety in the air and on the ground.
