Selecting FRS/GMRS Radios Repeater capable FRS/GMRS Radios with Amazon prices as of August, 2019- Motorola made 3 models (all discontinued). BTECH has 1 model: GMRS-V1 $45.00 / each Legal on all FRS/GMRS channels – no simple sub-channel selection Baofeng UV-82HP is a HAM radio with FRS/GMRS frequencies. LMOCERT sells it for $60 each and it can be reprogrammed once you get a HAM license. Radios have rechargeable batteries and charger; may also use AA alkaline cells Ignore “mileage” claims.

Sub-Channel Baofeng radios use the CTCSS codes (there are 38 standard codes) Lamorinda CERT normally uses sub-channel 0 which is None in CTCSS terminology Your radio is now ready for communications. Visual 9.6 Lamorinda CERT

CERT Programmed - MURS MURS (Multi-Use Radio System) The Baofeng UV-82HP radios are also programmed with the MURS frequencies on channels 76-80. These are low power simplex channels available to everyone. Normal FRS/GMRS radios do not have these channels available. Visual 9.7 Lamorinda CERT

RF Power Exposure and MPE Biological effects can result from exposure to RF energy. ... It has been known for many years that exposure to very high levels of RF radiation can be harmful due to the ability of RF energy to heat biological tissue rapidly. This is the principle by which microwave ovens cook food. Two-way radios use electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. Limits or Maximum Permissible Exposure levels have been set for RF radiation. Visual 9.8 Lamorinda CERT

RF Power Exposure Transmit no more than 50% of the time. Two-way radios are designed, manufactured, and tested to ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of two-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Transmit no more than 50% of the time. Use the lowest power possible to communicate. Visual 9.9 Lamorinda CERT
