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 nelle bande:
- Da 40.660 a 40.700 MHz, statuto secondario, massima BW 3 kHz, massima potenza 10 W (EIRP?)
- Frequenze centro banda 70.100 - 70.200 - 70.300 - 70.400 MHz, statuto secondario, massima BW 25 kHz, massima potenza 10 W (EIRP?)
- Obbligo di visibilità sulle attività di sperimentazione per una tempestiva gestione di eventuali disturbi.
