Can ChatterBox communicators communicate with other “Citizens Band” CB frequency radios?
No. The ChatterBox GMRS-X1, FRS-X2, HJC-FRS MultiSport+ communicators are FRS, or FRS/GMRS frequency radio communicators, and they are not compatible with CB frequency radios. GMRS X1 radios can communicate well with other Chatterbox communicators and other FRS or GMRS frequency handheld radio “such as Motorola FRS handheld radios” in the U.S. market. Chatterbox also has its own handheld radio transceiver will communicate with GMRS X1 radios. http://www.mwsbike.com/frs_pro_handheld If you have someone on the sideline or on anther vehicle to communicate with you, he or she can use a FRS or FRS/GMRS frequency radio.
