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.
