Definitions:
 
All modes: CW, SSB and those modes listed as Centers of Activity, plus AM (Consideration should be given to adjacent channel users)
Image modes: Any Analogue or digital image modes within the appropriate bandwidth, for example SSTV and FAX
Narrow band modes: All modes using up to 500 Hz bandwidth, including CW, RTTY, PSK etc.
Digimodes: Any digital mode used within the appropriate bandwidth, for example RTTY, PSK, MT63 etc.
Sideband usage: Below 10 MHz use lower side band (LSB), above 10 MHz use upper side band.
(*) Lowest dial setting for LSB Voice Mode: 1843, 3603 and 7043 kHz
Notes:
  • Amplitude Modulation (AM) may be used in telephony sub-bands providing consideration is given to adjacent channel users.

  • CW QSO's are accepted across all bands, except within beacon segments

  • Contest activity shall not take place on the 10, 18 and 24 MHz bands.

  • Non-contesting radio amateurs are recommended to use the contest-free HF bands (17 and 12 m) during the largest international contests.

  • The term " automatically controlled data stations" includes store and forward stations.

Transmitting Frequencies:

  • The announced frequencies in the band plan are understood as "transmitted frequencies" (not those of the suppressed carrier)

3.5 MHz band:

  • Intercontinental operators should be given priority in the segments 3500 -3510 kHz and 3775 - 3800 kHz.

  • Where no DX traffic is involved, the contest segments should not include 3500-3510 kHz or 3775-3800 kHz.

  • 3510 - 3600 kHz may be used for unmanned ARDF beacons (CWA1A)

 

10 MHz 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.

28-29 MHz band:

  • Operators are advised not to transmit on frequencies between 29.300 and 29.510 MHz to avoid interference to amateur satellite downlinks.

  • Preferred NBFM operating frequencies on each 10 kHz from 29.210 to 29.290 MHz inclusive should be used.

  • A deviation of + 2.5 kHz being used with 2.5 kHz as maximum modulation frequency.

 

50MHz band:

  • Telegraphy is permitted over the whole Band; Telegraphy exclusive between 50.000 - 50.100 MHz.

  • The intercontinental DX calling frequency 50.110 MHz should not be used for calling within the European part of Region 1 at any time.

    Amateur Service 50 - 52 MHz Secondary User:

    160 Watts PEP permitted - Available on the basis of non-interference to other services (inside or outside the Sultanate of Oman).
