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
