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
