GMRS/FRS Emergency Communication Channel

Something I just came across for GMRS and FRS Radio use in Colorado is the Emergency Channel. To specify it is the channel to use when Colorado Search and Rescue is already on the way after a 911 dispatch in the Colorado Backcountry. This is specifically Channel 3 with no privacy tones being used. Now of course this may be different for other states, so please double check as needed for travel. It can be helpful in an unwanted event of sorts.

 
While Channel 3 is common to both new and older FRS Radios, there is a significant transmitter power limitation (2 watts for FRS, 5 watts for GMRS). Had a channel in the 15-22 range been designated, a mobile GMRS radio (typically in a vehicle) would have a stronger signal, as they are allowed up to 50 watts of transmitter power.

Such a stronger signal (on Channel 15-22) could benefit both the victim and the SAR Responder if either, or both, had access to GMRS Mobile Radios.

Keep in mind that not everyone is going to have a mobile radio in a vehicle in an emergency situation like such. It's probably why they state Channel 3. Even with a good GMRS radio you can still have fair range with 5 Watts.
