Formed in 1982, Grantham Amateur Radio Club (GARC), an RSGB-affiliated club, is one of Lincolnshire’s oldest amateur radio clubs. 

We welcome anybody interested in radio communications to join our strong membership of amateur radio enthusiasts. Coming from all walks of life, our members are eager to enhance their technical knowledge, pass on their amateur radio experience, and have fun in the process.

Grantham Amateur Radio Club is a registered RSGB training centre, and our in-house trainers regularly run training courses for all three licence classes.

We organise Bi-annual IOTA expeditions, regular field days and special event stations. So why not get interested, attend our friendly meetings, and participate in our many activities? Including talks, demonstrations, competitions and quiz nights.

Generally, propagation conditions are best when the A index is 15 or lower, and the K index is 3 or lower.
