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’s your responsibility to set all controls so that trans-
mission in this band meets the stringent conditions
under which amateur operations may use these fre-
quencies.

NOTE: We recommend that you store these fre-
quencies, mode and filter settings into memory
channels for easy recall.

*The FCC specifies center frequencies on the

5 MHz band. However, the IC-7700 displays carri-
er frequency. Therefore, tune the transceiver to
1.5 kHz below the specified FCC channel center
frequency.
