IV3ONZ's Ham Radio Blog: Suddivisione IARU delle bande LF / MF / HF, Regione 1

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 in sottobande.

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.

Frequenze attribuite in Italia

Frequenze non attribuite in Italia

Dal 1 settembre 2024 al 31 dicembre 2024 è autorizzata la sperimentazione in Italia nella banda:

Da 1810 a 1830 kHz, statuto secondario.

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)
