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 comm
unicate with a 22 Channel GMRS
tuned to Channel 15.Please refer to the
chart below for channel/frequency
number compatibility.
