About the 5 MHz frequency band operation (USA version only)
Operation on the 5 MHz frequency band is allowed on
5 discrete frequencies and must adhere to the follow-
ing:
• The USB,
USB data, CW and PSK
modes
• Maximum of
100 watts ERP
(Effective Radiated Power)
• 2.8 kHz bandwidth (maximum)
It is your responsibility to set all controls so that trans-
mission in this frequency band meets the stringent
conditions under which amateur operations may use
these frequencies.
NOTE:
We recommend that you store these fre-
quencies, modes and filter settings into memory
channels, for easy recall.
To assist you in operating within the rules specified
by the FCC, transmission is illegal on any frequen-
cies other than the five shown in the tables below.
• For the USB and USB data modes
The FCC specifies center frequencies on the 5 MHz
frequency band. However, the transceiver displays
carrier frequency. Therefore, tune the transceiver to
1.5 kHz below the specified FCC channel center fre-
quency.

• For the CW and PSK modes
The transceiver displays the center frequency. There-
fore, tune the transceiver to the specified FCC channel
frequency when you operate in these modes.
