What is Amateur Radio?

Amateur (Ham) Radio is a hobby that combines interests in communications, electronics, digital technologies and other disciplines. Radio Amateurs use primarily radio based systems to talk or communicate with like minded people from all ages and walks of life across the planet.

Ham radio has a community social aspect and also can be competitive with regular competitions to DX or make long distance connections. The community also offer emergency communication to remote areas or those affected by adverse weather or disaster.

Regulation

In the UK Amateur licences are provided and regulated by the UK Office of Telecommunications (OFCOM) in conjunction with the Radio Amateur Society of Great Britain.

UK Band Plan (FAT)

Radio frequency spectrum is finite and its use is tightly controlled in the UK (as it is in most countries). OFCOM, the government organisation who controls how the radio spectrum is allocated and used in the UK publishes a reference document defining who can use which frequencies, under what circumstances and certain licence restrictions.

There are a number of licence free bands defined (used for example by WiFi, PMR and LowRa), however to transmit on most parts of the radio spectrum requires a licence, for which conditions need to be met to ensure the spectrum is used appropriately.

Amateur Licencing

In order to obtain an Amateur Radio Licence the operator needs to prove that they understand the basics of the hobby and the restrictions placed upon them by the license conditions. This is regulated by series of three exam levels that allow higher power and additional frequency use as the requirements to pass become increasingly demanding.

• Types of licence
  • UK Foundation Licence - Also known as Technician Class License in the US
  • UK Intermediate Licence - Also known as General Class License in the US
  • UK Full Licence - Also known as Class License in the US
• Training
  • Resources
• Exams

Note: Although there is some correlation between UK and US license structures, licensing, training and even frequency band plans are different across the world and licenses and exams are not interchangeable. If you are training for a Radio Amateur exam, be sure to use information resources dedicated to your country's organisational body. See below to links for Radio Amateur Organisations around the world.
