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 = 22 Channel GMRS
