Stepping into the world of radio communications can feel like tuning into a frequency that’s all noise and no signal. If you’ve spent any time in Facebook off-roading or overlanding groups, you’ve likely seen a mountain of conflicting advice about which “handheld” to buy or which channels are “free” to use. Unfortunately, there’s a lot of misleading and outright wrong information out there, and following that info can lead to heavy fines or, worse, significant safety risks. NOTE: The information / guidance in this article is for use of radios in Canada. Other countries have different regulations.

Radio types and options

So, which radio should you use? It really depends on the situation, but radios can be broken out into about five different categories.

FRS and GMRS

These are the “walkie-talkie” radios you typically find at big-box stores in blister packs. While they’re relatively cheap and easy to use, they have major limitations for vehicle-based use. Most of these radios are a hybrid FRS/GMRS radio, which means you’ll have both sets of channels on each radio.

FRS (Family Radio Service)	GMRS (General Mobile Radio Service)
No license required.	No license required for consumer handhelds up to 2 Watts.
Channels 8–14	Channels 1–7 and 15–22
Limited to 0.5 Watts. (You’ll often see forum/group chats where people say that 5 Watts are allowed in Canada, but it’s actually only 0.5 Watts.)	Limited up to 2 Watts.
Fixed / non-removable antennas only. (You will certainly see radios online that have removable antennas, especially for mobile GMRS radios, but these are not permitted in Canada.	Fixed / non-removable only for license-exempt use.
Range: Very short; typically under 1 km line-of-sight. Marketing claims frequently state much longer distances, but those are under absolutely perfect conditions where there are no obstacles (trees, buildings, mountains, people, vehicles, etc.)	Slightly better range (3–5 km line-of-sight).

Using FRS/GMRS around the campsite, event area or on a hike where groups are fairly close to each other is pretty much the only practical use for these radios.

Trying to use them in an overland / off-roading convoy is generally not going to work; especially if you’re expecting to use them between the lead and tail-end vehicles. Even using the higher-powered GMRS channels, your vehicle acts as a Faraday cage. (Think of your vehicle as you sitting in a microwave oven trying to use a radio with someone outside of the oven. The oven is going to block your signals (the microwaves) from getting out to people outside of it, and all those microwaves are reflected back – into you.)

Back to online groups and forums for a minute… In the US, it is legal to use GMRS radios up to 50 Watts, which is significantly higher than the maximum 2 Watts allowed in Canada. The US also allows you to have external/separate antennas and the combination of the higher power and better/external antennas makes GMRS a viable option for convoy scenarios. You can even set up GMRS repeaters in the US, which takes those signals and rebroadcasts them across an even wider area. While GMRS in the US doesn’t require an exam or test, it does require you to have a license, which can cover you and your family.

CB / GRS (Citizen’s Band / General Radio Service)

“Breaker breaker 1-9, this here’s the Rubber Duck. We got a smokey report: a Kojak with a Kodak hiding at mile marker 42, so back her down. What’s your twenty, come back?“

While CBs are still available for purchase and there’s no license required for use in Canada, they’ve (almost) faded into obscurity due to other radio options.

(PS: If you’re a fan of Stranger Things, the hand-held radios that Dustin, Mike and Will generally use are Realistic TRC-214 and TRC-219 radios – giant brick 3 Watt CBs with telescoping three to five foot (1 to 1.5 meter) antennas. While those are real radios, the range they got in the show was definitely “Hollywood magic” and nowhere near reality.)

Commercial Radio (LADD, RR, AB-Wide)

These are “life-safety” frequencies used by industrial traffic. They are NOT for casual chatter or use by the general public for convoy comms, and this is where some of the misleading and incorrect info you’ll see in Facebook groups and other forums starts moving into the “very illegal and very dangerous” realm.

Western Canada Commercial Radio Comparison

Feature	LADD 1–4 (Logging Administration Dispatch)	Resource Roads (RR 1–35)	LD 1–14 (Loading Channels)	Alberta-Wide / Alberta-Open
Primary Purpose	Public safety, government, trucking, and industrial convoy safety on major highways.	Safety and position calling on active logging, mining, and oil/gas roads.	Stationary, at-site industrial coordination (loading yards, gravel pits, well sites).	AB-Wide: Road control in Northern AB. AB-Open: Industrial site coordination.
How to Use It	Listen only for recreational users. Most active roads have switched over to RR channels.	Listen only for recreational users. Must tune to the specific road-posted channel.	Listen only. Never use LD channels for road travel or calling out kilometers.	Listen only for life-safety. Use AB-Wide if an industrial road has no posted RR sign.
The “Chatter” Rule	Casual conversation or trail talk is not permitted.	Chatting is strictly prohibited. Restricted to life-safety and location call-outs only.	Not for chatting. Idle chatter can jam communications between loader operators and drivers.	Not for chatting. Idle chatter can easily interfere with active logging operations.

Licensing

While a license is not required for listening, you must have a Light-Licensed Mobile license to transmit. There is no test/exam for this license, but does require yearly renewal (approx $50/year). While ISED-certified ham radios will typically allow you to program the frequency into your radio for receive (listening), they block the ability to transmit.

To register for a Light-Licensed Mobile license, visit the ISED Spectrum Management System. To be legal in AB and BC, ensure your license includes:

Using the Resource Road channels:

Amateur (Ham) Radio

Ham radio is the gold standard for long-range communications, but that massive increase in power and range comes with an increase in complexity and safety.

In Canada, any and all use of ham radios requires licensing. (There are two very specific exceptions: In an emergency, anyone is permitted to use a radio to call for emergency help. A non-licensed ham can use a ham radio as long as they’re under the direct supervision of a licensed ham, and what they can do depends on the license level of that licensed ham.)

There are three levels of licensing in Canada: Basic, Basic with Honours, Advanced.) For the most part, if you’re looking to use a ham radio for convoys / overlanding / off-roading, all you need is your Basic license.

NOTE: Regardless of which ham radio license you have, it does NOT permit you to transmit on the commercial frequencies (those LADD, Resource Road, Alberta Wide/Open ones mentioned above).

There are many online resources for learning about ham radio, and local ham radio clubs often have in-person and/or online training.

Satellite Comms

Devices like the Garmin InReach or Zoleo provide global SOS and texting capabilities. Some newer mobile phones also support satellite-based text messaging in emergencies.

Starlink provides you with high-speed internet for the backcountry, though it requires a reliable power source and a clear sky.

Why the Rules Matter: Splatter and Life Safety

Using uncertified radios can cause something called harmonic splatter—”ghost” signals that can interfere with those life-safety commercial calling frequencies, or emergency and aircraft frequencies. This means you can effectively deafen a loaded logging truck calling out a road marker location to other traffic, or impact STARS air ambulance or SAR teams during a rescue.

Transmitting without a license or using non-certified gear can result in $5,000 fines, equipment seizure, and a mandatory court appearance. If the radio equipment is mounted and wired to a vehicle, “equipment seizure” may include the radio AND the vehicle…

Safety Code 6: Don’t “Cook” Yourself

Radio frequency (RF) energy causes thermal heating of human tissue, and regardless of the type of radio you’re using, they all emit RF energy that carries your voice.

This is one of the reasons why FRS/GMRS radios that only operate at 0.5 to 2 Watts don’t require a license – the amount of RF they emit is extremely low. It’s also why radios with higher RF require licensing – there’s a safety aspect that you must understand, both for your safety and the safety of others.

For example, most mobile (vehicle-mounted) VHF/UHF ham radios can transmit up to 50 Watts of power. (Some can go higher than that, and mobile HF radios can easily double that.)

Having your mobile antenna mounted on your hood or fender or even a bull bar can put you and people around you at risk of exceeding federal exposure limits if you’re transmitting at the full 50 Watts for an extended amount of time. In most cases, even though you’ll see many vehicles with fender-mounted ham radio antennas, they’re transmitting at a much lower power (around 5 to 25 Watts) and for short periods of time.

But… but… What about those cheap radios on Amazon that can “do everything”?!

Purely from a technical perspective, yes – there are cheap radios on Amazon, Ali Express and other online stores that will allow you to program many frequencies into the radio. These include FRS/GMRS frequencies, amateur radio frequencies, air frequencies, LADD and RR frequencies and more. However, doing so is not legal and carries a much greater likelihood of causing interference and safety risks to you and others around you.

As an analogy, you can technically do a vehicle recovery by hooking a tow chain from the ball hitch of one truck to the axle of another truck. Do people do that? Yes. Will it work? Potentially. Should you ever do that? That’s a great big NO for many reasons… 🙂

In summary

The world of radio can be confusing, but also incredibly exciting and enjoyable. You’ll also find most hams are extremely helpful and willing to answer any questions you have. They often have informal coffee meetings or club meetings and those are a great way to get introduced to the hobby and to find people that will help you. (And when a real-life Stranger Things or SHTF scenario happens and there is no Internet, radio still works!)
