2-Way GMRS radios ( General Mobile Radio Service ) are good for group comms when there is no phone reception. Our FRS/GMRS radio GXT1030G by Midland. GMRS differs from CB ( Citizen Band ) and FRS ( Family Radio Service ) for its power. On channels 15-22 it transmits up to 50 watts. Channels 1-7 allow up to 5 watts and 9-14 only 0.5 watts. The reach of GMRS depends on the terrain. The fewer obstacles, the better. You can use a repeater to increase the range. Inside vehicles, they may not work well because we are in a sort of Faraday cage . A $35 license is needed to use GMRS. The license is good for 10 years and covers the whole family. Some folks advice using Channel 20 for emergencies - 462.675 MHz with PL tone of 141.3 Hz. This is called the "travel/calling" frequency, but only works if someone is listening and able to help. This is not an officially monitored channel.
