About 5 MHz band operation (USA version only)
Operation on the 5 MHz band is allowed on 5 discrete
frequencies and must adhere to the following:
• USB mode
• Maximum of 50 watts ERP
(Effective Radiated Power)
• 2.8 kHz bandwidth
It is the operator’s responsibility to set all controls so
that the transmission in this band meets the stringent
conditions under which we may use these frequencies.
NOTE:
We recommend that you store these fre-
quencies, mode and
fi
lter settings into the memory
channel for easy recall.
*The channel center frequencies that are speci
fi
ed
by the FCC, show the center frequency of their
passband. However, the IC-756PROIII displays
carrier point frequency, so set 1.5 kHz below from
FCC channel center frequency.

To assist you in operating the 5 MHz band correctly
within the rules speci

is impossible on any 5 MHz band frequency other
than the 5 frequencies indicated in the table above.
