Two-Way Radios 2.0: How the Landscape is Changing

By BCA Electronics Category Director Toni Leskela

Who would have ever thought that, in the era of smartphones, two-way radios would make a comeback? Well, they have, at least in the backcountry, where cell coverage can be sketchy. Not to mention, instant real-time group communication (with two-way radios) is much more valuable when scoping lines than dialing each other up on the phone. But in the alphabet soup of two-way radio technology, there’s lots of confusion about which ones to use. So we’re going to explain it, then talk about how the landscape around two-way radios is changing for next season, including what’s in store for the BC Link 2.0.

There are two radio services recreational users can use without jumping through massive numbers of hoops with the FCC (Federal Communications Commission). These services are FRS (Family Radio Service) and GMRS (General Mobile Radio Service). Using the GMRS service requires a license from the FCC–although most consumers ignore this rule and don’t get caught.

You’ve probably also heard about UHF and VHF radios. UHF and VHF are frequency areas where radios are operated. VHF (Very High Frequency) radios operate in the 30MHz to 300MHz frequency range and UHF (Ultra High Frequency) operate in the 300MHz to 3GHz frequency range. Generally, radios with open access to all of these frequencies require permission from the FCC and often involve the user getting assigned to a reserved frequency.

The Family Radio Service (FRS) is a private, two-way, short-distance communication service used for family or group activities. FRS channels are most commonly used through small hand-held “walkie-talkies,” such as the Motorola Talkabout and BC Link. FRS has 22 channels in the 462 MHz and 467 MHz range, and transmit at 2 watts (W). FRS is also compatible with the General Mobile Radio Service (GMRS) although, unlike GMRS, FRS does not require a license.

GMRS allows similar communications as FRS and data for GPS location information (such as that featured on the Garmin Rino). GMRS broadcasts up to 5W on handheld devices. GMRS does require a license in the U.S., but not in Canada. To apply for a GMRS permit, go to www.fcc.gov/forms/or call (800) 418-3676. An individual with a GMRS license can facilitate the activities of licensees and their immediate family members on one or more stations. A GMRS license term is ten years, as the FCC increased it from a five-year term in 2017. With the latest changes to FCC Title 47 Part 95, all existing BC Link radios are operating as FRS radios (transmit power 2W or less and bandwidth of 25kHz) and therefore are license-free.

Both FRS and GMRS radios operate in the UHF band, while most of the national park and guiding services operate on the VHF band. UHF radios can be programmed to operate on the FRS frequencies, but beware: the FCC has extremely high fines for creating interfering transmissions. Examples of interfering transmissions include using the wrong bandwidth or transmit power–or using unauthorized frequencies.

Both UHF and VHF frequencies are line-of-sight radios. This means that no matter what the transmit power, obstacles like mountains, ridgelines, and even large buildings will block transmission. VHF is affected slightly less than UHF due to VHF’s lower frequency. That is why VHF is more popular among park services, search-and-rescue, and military organizations. Fun fact: avalanche transceivers operate at the medium frequency of 457kHz because it penetrates snow much better than higher frequency UHF and VHF signals (even higher frequencies are nearly useless under snow, like those used on GPS units).  To overcome the problem of having line-of-sight functionality only, parks, guide services, police, and ski resorts often install repeaters on mountain tops and high buildings. These repeaters are mainly used by professionals, but now technology is also available for GMRS users.

To use an open-frequency UHF/VHF radio, users need to have proper education, such as that required to obtain a ham radio license. However, the use of radios in any revenue-generating operation requires the operator to have an FCC business license within a dedicated frequency. Using UHF/VHF radios requires following certain protocols that minimize extraneous transmissions: for example, even if you have a ham license, you could get fined if you used your radio to tell your employer you’re going to be late for work. In the case of emergencies, however, there are no penalties for using any frequency, no matter what license you have.

  • The BC Link 2.0 with Smart Mic is a 2W FRS/GMRS radio. Doubling the power will increase the range over the BC Link, but won’t double it: All line-of-sight radios require (expensive) repeaters to extend the signal  past large obstacles such as ridgelines.


  • Typical handheld UHF/VHF radios transmit at 5W. They requite a license and usually a dedicated frequency. To increase their range, operators usually install repeater systems. UHF/VHF radios are mainly for professional fleet  use.

  • Inexpensive 0.5-1W FRS/GMRS and FRS-only  radios such as the Motorola Talkabout are often sold in pairs at “big box” retail stores. These are not ideal for winter recreation, as the batteries don’t last long in cold temps–and they don’t come with remote speaker mics. These are often called “walkie talkies” or  “family band” radios.

Deciding which radio service to use depends on what activity you’ll be engaging in. The short-range reception of FRS radios is best for non-critical communications. FRS is mainly transmitted through “walkie-talkies” and is commonly used for everyday recreation, sports, and business communications. FRS channels can’t be reserved, so they can become crowded. This can be mitigated by avoiding popular channels and privacy codes (like 10-4 or 9-11). The widespread availability and inexpensive prices of walkie-talkies have made FRS more of a consumer (versus professional) frequency band.

So, what has changed since the FCC’s recent update on Title 47 Part 95 (in November of 2017)?

First of all, FRS/GMRS combination radios will be unlawful to import, manufacture, sell or otherwise offer starting November 2018. The good news is that you can legally keep using your existing FRS/GMRS radio–like the BC Link–under the new rules. According to the new FRS rules, channels 1-7 and 15-22 have a maximum transmit power of 2W and channels 8-14 have a maximum transmit power of 0.5W. The old rules limit the maximum transmit power in combination FRS/GMRS radios—like the BC Link–to 0.5W on channels 8-14 (and to 2W on FRS-only radios). Also, FRS radios continue to be license-free while new GMRS radios require licensing. The maximum transmit power on new GMRS channels can be up to 50W–although in the common world of handheld radios, it is 5W). Finally, the use of repeaters is now possible in the GMRS world.

As you can see, the landscape around two-way radio technology is complicated and involves lots of regulations and red tape. But we’ve waded through all this and are proud to be shipping our new BC Link 2.0 this fall. This unit takes advantage of the new FCC rules and allows us to use a maximum of 2W instead of the maximum 1W on our original BC Link. The 2.0 also has some nice improvements, including a smaller Smart Mic, a robust cord/base unit connection, and more weatherproofing. Keep your eyes out for it at your local retailer!
