Nota la ripartizione delle frequenze, stabilita da ogni Paese con una propria legislazione, per conoscere il tipo di emissione e la banda occupata utilizzabile la IARU, l'Unione Internazionale dei Radio Amatori, suddivide a sua volta ogni banda di frequenze.
Questa suddivisione è subordinata alla concessione delle frequenze; quindi particolari modalità come potenza massima, limiti di frequenza o statuto devono essere seguiti secondo la normativa locale vigente.

DEFINITIONS
| All modes | CW, Phone and those other modes listed as Centres of Activity, plus AM (consideration should then be given to adjacent channel users) |
| Narrow band modes | All modes using up to 500 Hz bandwidth, including CW, RTTY, PSK etc. |
| Digimodes | Any digital mode within the appropriate bandwidth, e.g. RTTY, PSK, MT63 etc |
| Image modes | Any analogue or digital image modes within the appropriate bandwidth, e.g. SSTV, FAX |
NOTES
The frequencies in the bandplan are understood as “transmitted frequencies” (not those of the suppressed carrier!)
| (1) | Lowest dial setting for LSB Voice mode: 1843, 3603, 7053 kHz |
| ( # ) | maximum bandwidth not specified, 500 Hz suggested |
| ( ## ) | Highest dial setting for USB Voice mode on the 60m band: 5363 kHz |
| CW | CW QSOs are accepted across all bands, except within beacon segments. (DV05_C4_Rec_13) |
| Sideband usage | Sideband Usage: Below 10 MHz 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. |
| AM | Amplitude modulation (AM) may be used in the telephony sub-bands providing consideration is given to adjacent channel users. (NRRL Davos 05). |
| OUT OF BAND: | To prevent any out of band transmission the maximum dial setting for USB (upper sideband) Voice mode should be 3 kHz below upper band edge on bands 20m to 10m. |
| 630m band - 472 - 479 kHz: | Details shown in band plan above should be understood as "proposed usage" (VA14_C4_Rec_02) |
| If a frequency is to be selected, particular attention must be paid to still existing Non Directional Beacons (NDB) of the radionavigaton service! | |
| 60m band - 5351.5 - 5366.5 kHz | Details shown in band plan above should be understood as "proposed usage" (LA17_C4_REC_02) |
| It is strongly recommended that frequencies within 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. | |
| Contests | Contest activity shall not take place on the 5, 10, 18 and 24 MHz bands. |
| 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) | |
| Member societies are encouraged to publish contest operating segments clearly in the rules of their contest and | |
| that those segments are considered with due respect to the IARU band plans. (Rec SC11_C4_02). | |
| The CW contest-preferred segment from 7000-7025 kHz has been withdrawn from the Region 1 band plan. | |
| Societies should (therefore) encourage contest organisers to include a rule that restricts contest activity to a limited | |
| frequency range within the CW allocation. The choice of the frequency segment is left to the disccretion of the | |
| contest organisers, but should take into account expected activity levels and show consideration for | |
| non-contest operation. (SC11_C4_Rec_05). | |
| Unmanned transmitting stations | The term “automatically controlled data stations” includes Store and Forward 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) | |
| 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 61-01 agreement only applies to people using their own call sign, with the appropriate country prefix, | |
| when the operator is actually vising that country, not for operation. | |
| 3. Any further requirements regardingthe participationof remotely controlled stations in contests or award programms are a matter for | |
| the various contests or award program organisers. (SC11_C4_REC_07) , (VA14_C4_REC_04) |
