What is the purpose of radio communications?


Do you enjoy the outdoors? Hiking? Camping? Overlanding? Then a dependable communication system may be something you want to look into. Cell phones are limited in the wilderness and for the most part cant get reception. This is where a a 2 way radio or an amateur radio can give you the peace of mind when you are on your adventure.

Besides normal communication there are so many other valuable things a radio can provide you.

If your car breaks down or someone gets injured, having a radio can get you out of a pinch.

Two way Radios have instant communication, all you have to do is hold down the PTT button and you are communicating instantly. There are many applications to this type of communication. 

You can communicate within a small group. As long as everyone is on the same frequency/channel, groups can be connected without the need of cell signal or internet.


Who uses two way communication?

Transportation Companies

Government Agencies




Fire and Police Departments

Utility industries

Military and other intelligence agencies.





Ham and GMRS are some of the best amateur radio choices you can have in 2022. There are a strong market support for these devices in the outdoor world and especially the overlanding scene. Even though they are not that much different from each other, there are a couple of differences that you might want to think about when deciding which route to go.


What is GMRS


GMRS stands “ General Mobile Radio Service” for GMRS are extremely popular these days. Known as “Class A Citizens Band” it was renamed by the FCC is 1987. It uses the same frequency bands as Family Radio Service  “FRS’s” (462-467MHz). The major difference is GMRS has designated channels that are not available on FRS radios. 

 Their extremely versatile and portable designs are a big hit. Besides voice communication, GMRS has GPS location and short-distance texting applications which make it extremely useful for emergencies. FRS and CBS communications also use the same features.


GMRS works well for family or small group type of communication. Ten to fifteen miles of range is easily achievable and some repeaters are available. For this specific blog we are talking about why it is valuable for overlanding. When a group of vehicles are traveling down the highway or off the beaten path, it is much easier to communicate via radio versus trying to use your cell phone. Many off-road vehicle clubs are now using GMRS as their main form of communication. Other outdoor activities such as hiking, camping, hunting etc.. use GMRS to stay in touch while not depending on cell phone.

GMRS radios are used for short distance communications because of the absence of repeater towers. There are new technologies that are allowing GRMS radios to use specific type of repeater towers. 



What is HAM


The hobbyist radio, HAM radio is the amateur radio. One of the reasons that this radio is also another good option is that there are no communication range limitations with HAM. Generally, people prefer ham because it does not usually have an extremely complicated set up and is easy to use. HAM radios do require a license. Once a user proves that they have acquired the knowledge needed to operate this type of radio and pass the government test, you are good to go.

In addition HAM uses specific frequencies, so it won’t disrupt commercial or local channels (GMRS channels)

 Ham radios are best known for its huge impact in survivalist situations (most extreme). The wireless technology offers reliability beyond the possibilities of power grids and cell networks. This is also the preferred communication channel for remote areas. 

Basic Ham radios use radio waves to broadcast, transmit and receive information from one person to another (or groups). 

 An amateur radio operator is an individual who typically uses equipment at an amateur radio station (or even their own home) to engage in two-way personal communications with other similar individuals, on radio frequencies assigned to the amateur radio service by the Federal Communications Commission (FCC) in the United States and the International Telecommunication Union worldwide. There are many hand held options now that you can purchase but depending on the radio may be less dependable.

*UHF is much stronger than VHF and can transmit through various obstacles, but the frequencies are incompatible with each other.


Radio Repeater

radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. A repeater sited at a high elevation can allow two mobile stations, otherwise out of line of sight propagation range of each other, to communicate. Repeaters are found in professional, commercial, and government mobile radio systems and also in amateur radio


Ham radios use these type of repeaters to communicate which means the length they can transmit is endless (specific set ups)






Why is GRMS a better choice than amateur radio for the weekend warrior


1. GRMS is not as technical or complex as HAM 

2. Requires license but does not require a test, just a fee.

3. GMRS has straight forward dedicated frequencies that are locked into channels and you wont accidentally cross over to a official Ham radio users frequencies.

 Hey I'm on channel 20" versus hey "I'm on 456.765"

4. Easier to learn when meeting with groups 

5. GMRS set ups are extremely easy to use and run in vehicles


Ham is the far superior type of communication if you are looking to go farther and even talk to other hobbyists with the same interest, but personally I found GMRS are usually enough for the weekend warrior that is trying to stay in communication with family, friends or the caravan. You can walk into most outdoor oriented stores or even a local Walmart and pick up a GMRS radio. 

Once again it is preference but for the average Overlander/Camper/Hiker can use, GMRS is all you will need.
