How to set up a GMRS communication plan for family trips?

April 5, 2026

Quick Answer

To set up a GMRS communication plan for family trips, assign a unique call sign to each family member, designate a primary and secondary channel for group communication, and establish a communication protocol for emergency situations. Use channel 1-22 for group communication and reserve channel 22 for emergency use only. Consider using a repeater to extend communication range.

Setting Up Your GMRS System

Before heading out on your family trip, ensure each member has a GMRS radio and knows how to use it. Assign a unique call sign to each family member, such as “Family1”, “Family2”, etc. Designate a primary channel (e.g., channel 1) and a secondary channel (e.g., channel 2) for group communication. Establish a communication protocol for emergency situations, such as using a specific call sign (“EMERGENCY”) to signal a crisis.

Channel Management

To prevent channel congestion, use channel 1-22 for group communication and reserve channel 22 for emergency use only. Consider using a repeater to extend communication range and improve signal quality. Repeater setup typically involves using a repeater with a frequency of 462.525 MHz, a transmit frequency of 462.525 MHz, and a receive frequency of 462.525 MHz.

Establishing a Communication Protocol

Develop a communication protocol that outlines the procedures for group communication, emergency situations, and maintenance checks. Establish a routine for regular check-ins, such as every hour, to ensure all family members are accounted for. Consider creating a communication tree, where each member reports to a designated leader or “hub” family member. This helps to centralize communication and ensure that everyone is informed of important updates.
