National Regulations and Guidelines

Operational Bands

  • Annex 1 of the ComReg Guidelines includes details of the the frequency bands which an amateur station is authorised to operate on, along with details of the power limits, modes and other stipulations for each band.  The frequencies covered by this table range from 135.7 kHz to 47,200 MHz: however the Syllabus indicates that only bands listed in the table below are within the scope of the exam
  • The table below shows the frequency allocations, the status of these allocations and power limits, all of which would be relevant for exam purposes.  Although the ComReg guidelines also specify the allowable modes for each frequency range, we have listed them in the Band Plan section of the Course Guide, because the preferred modes under the band plans are often a sub-set of the modes allowed under the Guidelines

  • See Primary and Secondary Allocations for more information on Status
  • For the purposes of the above Power Limits, the power is measured at the output of the transmitter or amplifier
  • The separate power limits for contest operation are outside the scope of the exam syllabus
