The Electromagnetic Field is a non-profit camping festival for those with an inquisitive mind or an interest in making things: hackers, artists, geeks, crafters, scientists, and engineers. Electromagnetic Field 2024 will be held on 30 May–2 June 2024 at Eastnor Castle Deer Park, Eastnor, Ledbury.

AMSAT-UK, BATC & UKuG are setting up a 'village' that will host a variety of demonstrations and presentations during the weekend.

AMSAT-UK Represents the amateur satellite community in the UK whose members not only operate amateur satellites but also help to design, build and fund them.

BATC The British Amateur Television Club (BATC) actively promotes the hobby of Amateur Television and covers all aspects of Television from making and editing programmes to transmitting television on the amateur radio bands. During EMF Camp, presentations will be given on the subjects, in addition to making video contacts via the QO-100 geostationary satellite. operations.

UKuG The UK Microwave Group is the body who represent Amateur activities and developments in the high UHF and microwave parts of the radio spectrum.

There is a wide cross-over in the activities and interests of these three groups. And regularly work together to further the many projects and issues that affect Amateur Radio in the UK. At EMF-2024 these three organisations will be demonstrating various aspects of the hobby. Including low earth orbiting and geostationary satellite communications and possibly deep space reception. Microwave contest operation. Digital television via terrestrial links and via the QO100 transponder, aboard a geostationary satellite. And a random selection of other interests, which members would like to showcase.

GB4EMF Amateur Radio Special Event callsign during EMF for all contacts.

G0AUK The AMSAT-UK (Club) callsign will also be in use.
