Who we are

The permanent HF Committee (C4) deals with matters relating the frequencies below 30 MHz.

What we do

  • We co-ordinate the activities of amateurs in Region 1 with respect to frequency allocations below 30 MHz
  • We ensure that adequate use is made of existing allocations and to consider possible new allocations
  • We co-ordinate and promote scientific investigations by member societies of IARU Region 1 on all frequencies below 30 MHz.
  • We recommend IARU Region 1 bandplans aimed at promoting greater effectiveness for communications
  • We encourage special projects on the frequency allocations below 30 MHz aimed at advancing amateur radio communication techniques
  • We assist in the protection of the amateur allocations below 30 MHz from possible loss by stimulating activity and demonstrating the effective use by amateurs
  • We plan and conduct IARU Region 1 HF contests on these bands
  • We advise on interference problems relating to frequencies below 30 Mhz
  • We maintain communication with Member Societies through
    - an Internet reflector discussion group
