General Specifications
A.FRS/GMRS Frequency Allocation and Compatibility
Important: Please note that Cobra® GMRS models with 15 channels may designate different channel numbers for the same frequency. For example, a Cobra® 15 channel GMRS model would need to be tuned to channel 11 in order to communicate with a 22 channel GMRS tuned to channel 15. Please refer to the chart below for channel/ frequency number compatibility.
A = Channel No. For
22 Channel GMRS Models
B = Channel No. For 15
Channel GMRS Models
C = Type of Radio Service
D = Frequency in MHz
E = Power in Watts
