30m Band Plan

The 30m Amateur Radio band is allocated to the Amateur Radio Service on a Secondary basis. Radio Amateurs must not cause interference to Primary Fixed Service Users.

All frequencies in kHz

  • 10100-10130 CW only, bandwidth 200Hz or less
  • 10130-10150 CW & Digital modes bandwidth 500Hz or less
  • 10140-10150 Region 2 only: digital modes up to 2700Hz bandwidth

Notes:

  • The 10.1 MHz band is allocated to the Amateur Service only on a Secondary basis. Primary allocation is to the Fixed Service.
  • The IARU has agreed that only CW and other narrow bandwidth modes are to be used on this band.
  • SSB may be used during emergencies involving the immediate safety of life and property and only by stations actually involved in the handling of emergency traffic.
  • The band segment 10120 to 10140 kHz may be used for SSB transmissions in the area of Africa south of the equator during local daylight hours.
  • News bulletins on any mode are not be transmitted on the 10.1 MHz band.
  • No contests are to take place on the 10.1 MHz band.
  • DX operations should adhere to the 200Hz bandwidth limit and operate split only when necessary.
  • All radio amateurs must monitor their frequency of transmission at ALL times when operating split within the above limitations, in order to be able to comply with cessation of transmission request by Primary Fixed Service users.
  • 10116 is QRP centre of activity. Please give priority to low power stations.
  • There is no Mobile Service allocation, all mobile fishing vessels etc are intruders.
  • Beacons should be avoided (with the sole exception of DK0WCY)
  • Automatically controlled data transmissions (unattended) should avoid use of the 10.1 MHz band.
  • In Region 2 the segment 10140 to 10150 kHz may be used by digital modes with up to 2700Hz bandwidth.
  • Australia: authorities in Australia have, against IARU recommendations, allowed SSB transmissions within Australia and the Wireless Institute of Australia has specified 10125 to 10135 kHz to be used during local daylight hours only. SSB users in Australia are however disregarding this advice and continue using the segment 10115 to 10125 kHz thus causing harmful interference to CW operations within and outside Australia including popular CW clubs.
  • Brazil: authorities in Brazil have, against IARU recommendations, allowed SSB and other wide band modes in the 10.138 to 10.150 MHz band with a band width of up to 3 kHz.
