It is strongly recommended that frequencies within the WRC-15 allocation only be used if there are no other frequencies available at 5 MHz under domestic (ITU-R article 4.4) permissions. 

 

Local nets and long rag chew QSOs should not use the WRC-15 allocation at 5 MHz but should instead make   use of the 3.5 MHz, 5 MHz domestic, or 7 MHz bands where there is more spectrum available.

DEFINITIONS

 

 

All modes                   CW, SSB and those modes listed as Centres 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.

 

 

NOTES

 

The frequencies in the band plan are understood as “transmitted frequencies”  (not those of the suppressed carrier!)

 

To prevent any out of band transmission the maximum dial setting for USB Voice mode should be 3 kHz below upper band edge on bands 20m to 10m. 

 

          (*)                                Lowest dial setting for LSB Voice mode: 1843, 3603 and 7053 kHz

 

          (##)                             Highest dial setting for USB Voice mode on the 60m band: 5363 kHz 

 

 

CW QSOs are accepted across all bands, except within beacon segments. (Recommendation DV05_C4_Rec_13)

 

 

Amplitude modulation (AM) may be used in the telephony sub-bands providing consideration is given to adjacent channel users. (NRRL Davos 05).

 

 

 

Sideband Usage

 

Below 10MHz lower sideband (LSB) is recommended, and above 10 MHz use upper sideband (USB). 

 

The exception to this is on the 5 MHz band where USB is recommended.

 

   630m band: 

Details shown in the band plan above should be understood as “proposed usage”.  (VA14_C4_Rec_02)

 

 

60m band: 

Details shown in the band plan above should be understood as “proposed usage”. (VIE14_C4_Rec_02)

 

 

Contests

 

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

 

Non-contesting radio amateurs are recommended to use the contest-free HF bands (30, 17 and 12m) during the largest international contests. (DV05_C4_Rec_07)

 

Contests should be restricted to 160, 80, 40, 20, 15 and 10m. That is 60, 30, 17, and 12m bands shall not be used for contests. (VIE16_C4_Rec_06 *) ( * to be ratified at General Conference 2017)

 

        For more recommendations about contest segments see the IARU Region 1 HF Manager Handbook. 

 

                 

Unmanned transmitting stations:

 The term “automatically controlled data stations” includes Store and Forward stations.

 

IARU member societies are requested to limit this activity on the HF bands. 

It is recommended that any unmanned transmitting stations on HF shall only be activated under operator control except for beacons agreed with the IARU Region 1 beacon coordinator, or specially licensed experimental stations.  

 

Member Societies are reminded of the recommendation in the IARU Region 1 HF Band Plan ‘that any unmanned transmitting stations on HF shall only be activated under operator control, except for beacons agreed with the IARU Region 1 Beacon Coordinator’. 

 

Unmanned transmitting stations, and operation involving unmanned transmitting stations, must adhere to the frequency and bandwidth limits of the band plan.

 

The operator connecting to an automatically controlled unmanned transmitting station is responsible for not causing interference. This is particularly important in the 30 meter band where the amateur service only has secondary status.

 

Amateur radio operators may transmit messages via unmanned transmitting stations during coordinated emergency, and disaster preparedness exercises, limited to the duration of such exercises, using a bandwidth not exceeding 2 700 Hz. 

 

Such communication should be announced regularly on the frequency, and radio amateurs not participating in the communication should cooperate by not transmitting on the frequency. (VA14_C4_Rec_06).

 

Beacons

 

For information about IARU Region 1 beacon policy see the IARU Region 1 HF Manager Handbook.

 

Remote controlled operation on HF

 

 

Remote controlled operation is defined to mean operation where a licensed operator controls an amateur radio station from a remote control terminal.

 

Where a station is operated remotely, the following conditions shall apply: 

Remote operation must be permitted, or not objected to, by the Regulatory Authority of the country where the station is located.

 

1.     The call sign to be used should be the call sign issued by the Regulatory Authority of the country in which the station is located. This applies irrespective of the location of the operator.

 

2.     It should be noted that the CEPT T/R 61-01agreement only applies to people using their own call sign, with the appropriate country prefix, when the operator is actually visiting that country, not for remote operation.

 

3.     Any further requirements regarding the participation of remotely controlled stations in contests or award programs are a matter for the various contest or award program organisers.
