The Isles of Scilly are designated EU-011 in the Islands on the Air (IOTA) directory.  Please consult QRZ.com for contact details. M1IOS, is one of two, Amateur Radio Stations on the Islands. Radio Station M1IOS is located at 0.5 metres above sea level, on a narrow sand bar, in the centre of Hugh Town, St. Mary’s, Isles of Scilly. It is in the lee of a low hill to the west. From M1IOS, two-way radio communications are conducted between the Isles of Scilly and a variety of worldwide locations, including for example; Australia, Japan, Brazil, Zambia, Kazakhistan, Lebanon, USA, The Caribbean, the United Kingdom and European stations. Two very small gardens to the front and rear negate the erection of wire or beam antennae. An effective ground plane has been developed. Two 2.5 metre aluminum poles have been driven into the sandy soil below the level of the high tide. Additionally, copper sheet and wire had been buried into the small rear and front gardens. The rear of the property contributes to a high level of background electrical noise. There is an electrical power substation, overhead power transmission lines and numerous sources of electrical magnetic interference, including telephone cables. The various Yaesu noise reduction systems, help to remove some background noise and other local spurious electromagnetic interference.  The Main Station transceiver is the Yaesu FT920AFC, with  narrow filters fitted.  The Yaesu FT1500M is used for Main Station VHF, FM contacts and for accessing the UK, Irish and French 144MHz Repeater networks.

Portable operations are conducted from various locations around St. Mary’s and the Off-Islands.  Notably, CASHOTA activity takes place from four of the islands fortifications.  The Yaesu FT857D transceiver is used for portable operations with the Wonder Whip.

  • HF Bands - 1.8MHz, 3.5MHz, 7MHz, 10MHZ,18MHz, 21MHz, 24.5MHz and 28MHz.
