Best Walkie Talkie Channels: What Walkie Channels Should I Use?

If you’ve recently ventured into the world of portable radios, you may have several questions in mind, such as what walkie-talkie channels to use? Although relatively simple to operate, it’s essential to know the best channel for each situation type because different radio channels serve different purposes. 

We’ll provide you with an in-depth guide on identifying a suitable transceiver, bandwidth, and channel for indoor and outdoor use. 

What are channels on a walkie-talkie?

Walkie Talkie channels are a means to partition the radio frequencies. This helps when multiple users are trying to communicate. The channels prevent people from talking to each other. Two-way radios transmit and receive signals on different frequency bands and channels represented as Hertz (Hz). When communicating with friends and family, you need to set both devices to the same frequency/channel. The Family Radio Service (FRS) and General Mobile Radio Service (GMRS) are frequencies available for public access in the US.

FRS/GMRS radio handsets use 22 channels with a set corresponding power output needed to communicate. Most walkie-talkies come with pre-set channels operating at specific bandwidths. You also get the option to customize and set your channels on some handsets. Regardless of whether you plan on using the device indoors or outdoors, it’s best to opt for a device with several channels. It helps minimize unwanted interruptions. Having a greater number of channels helps when you have multiple groups using walkie-talkies to communicate. You can have group 1 communicating via channel 1, and group 2 communicating via channel 2, and so on. 

What is the best channel for walkie-talkie?

Two-way radios operate in the Ultra-High Frequency (UHF) and Very High-Frequency Band (VHF). You can set the device to any channel, depending on your need. 

Communicating outdoors

If you’re an outdoor enthusiast and enjoy hiking, camping, or biking, then walkie-talkies operating on the VHF bandwidth are an excellent choice. These radios operate at 136-174 MHz and have eight channels. 

VHF radios work well outdoors where there is little to no obstruction. Its radio waves propagate further away, enabling long-distance communication. However, since the radio waves are wider, they may not penetrate obstacles, such as walls and floors within a building. It’s important to note that VHF talkies may not work well outdoors with obstructions, such as trees or hilly terrains. This type of walkie-talkie works best in air and sea industries. Any channel within the bandwidth is the best walkie-talkie channel for long-distance communication.


UHF walkie-talkies operate at 400-512 MHz and are preferred over VHF for indoor communication. That’s because they are better at penetrating obstructions than VHF.  

Therefore, UHF channels are a better choice when you’re looking for crystal-clear transmissions within a building. They can penetrate walls, floors, doors, buildings, windows, and trees easily. But, the shorter radio wave means these devices are also efficient when looking for short-range communication. If you expect these to work when out running errands or hanging out with friends, these might not work. 

Outdoor and Indoor

If you want to experience the best of both worlds, some walkie-talkies support both VHF and UHF bands. This saves you from purchasing two different handsets for indoor and outdoor use. A dual-band walkie-talkie has more channels and can cover both short and long distances. Whether you’re inside a building or out in flatland, a dual-band device will give you static-free, crystal-clear transmissions. 

These devices offer both FRS and GMRS and allow you to choose between channels as per your requirement. These walkie-talkies have 22 channels with varying power output, depending on the channel you select. You can expect to reach up to 2-miles on the FRS channels (1-14); therefore, it’s ideal for smaller areas. For more significant sites with poor signal reception, GMRS is a better choice as these channels operate on higher power output. If you wish to reach over 2-miles away, the GMRS channels are your best option. Additionally, you can use privacy codes to minimize unwanted interference. 

Emergency communications

Two-way walkie-talkies do not have a specific emergency channel like CB radios. When faced with a threat to safety, you can tune into any available channel and call out in SOS. Anyone tuned in to the same channel will then be able to help you. In such a case, it’s best to avoid using privacy codes to increase your chances of reaching someone. For GMRS radios, check channel 20 (462.275 MHZ) in case of an emergency. 

What walkie-talkie channel should I use?

Walkie talkies send and receive messages on specific bandwidths and frequencies. You can choose between different channels, depending on your location. VHF radios are an excellent choice to communicate in open land with limited obstructions. On the contrary, UHF radios are recommended for indoor communication, with a short radio wavelength. Therefore, they’re better at penetrating obstacles, such as trees, windows, and walls, than VHF devices. 

You can also find walkie-talkies with dual-band capabilities that work on both VHF and UHF bands. Having both frequencies can cause better communication, as they will work regardless of your location. Given their versatility, I recommend purchasing transceivers that offer both VHF and UHF frequencies.

On the whole, it’s essential to consider where and how you’ll be operating before selecting the walkie-talkie channels to use. Before using your walkie-talkie, you should also look at the walkie-talkie channel not to use too.
