A visual aid depicting the specific radio frequencies allocated for General Mobile Radio Service (GMRS) communication, formatted for convenient printing and reference. Such a document typically lists the channel number, its corresponding uplink and downlink frequencies (if applicable, as with repeaters), and the assigned channel use, like simplex or repeater operation. It serves as a ready reference for GMRS users to ensure they are operating on the correct frequencies and adhering to regulations.
The utility of a readily available frequency listing stems from the need for clear communication and regulatory compliance. GMRS operations are governed by specific rules regarding frequency use, power levels, and permissible communications. Having a printed guide allows users in the field, where access to digital devices may be limited, to quickly verify their channel settings, avoiding unintentional interference or violations. The history of GMRS has seen modifications to its frequency allocations and regulations, making an updated chart an essential tool for all users.
Therefore, understanding the structure of these charts, the information they contain, and how to interpret them is crucial for responsible and effective GMRS communication. The following sections will detail the common elements found within these charts and provide guidance on their practical application.
