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 filter settings into the memory
channel for easy recall.

*The channel center frequencies that are specified

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.

5.33050 MHz

5.33200 MHz

5.34650 MHz

5.34800 MHz

5.36650 MHz

5.36800 MHz

5.37150 MHz

5.37300 MHz

5.40350 MHz

5.40500 MHz

To assist you in operating the 5 MHz band correctly
within the rules specified by the FCC, transmission
is impossible on any 5 MHz band frequency other
than the 5 frequencies indicated in the table above.
