Common use radio channels are popping up all over the place. This will be a page that lists all the different areas that use common use radio channels. If there is one that I have missed please email me info@skibumlyfe.com and I will add it to the list.
Common radio channels
No matter where you backcountry, you can usually find someone on the radio channel 4-20. It is also common practice to use the channel equivalent to the area code of where you are. For instance, in Tahoe-Truckee, you can find others on channel 5-30. Of course, many groups choose to use other channels to avoid chatter when communicating with their group. And these other channels are important to be aware of in case you need to reach out for additional assistance.
Radios
The most common radio types are FRS / GMRS radios. The ones that you see at Wal Mart and other box stores use FRS and are limited to 2 watts of power, even the BCA Link 2.0 is 2 watts. If you step up to the GMRS radios they can use repeaters and more power, typical handhelds will be 5 watts of power. More power means that you can connect even farther. If there is a repeater on the top of a nearby mountain you can reach even farther with that radio.
If you use GMRS radios they do require a license from the FCC and are good for the whole family. There are no tests to take, just pay the fee and it is good for 10 years.
