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
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.
