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.

Feel free to join our friendly meetings if you are interested in Amateur Radio. The club gathers every first Tuesday of the month at Great Gonerby Memorial Hall on Belton Lane, Great Gonerby. You can find the location map by clicking the link provided. (Click for location map)
Please refer to our club calendar, Facebook page, or Twitter to stay informed about upcoming meetings and events. All meetings commence between 19:30 and 20:00 and run until around 21:30. We look forward to meeting you!

The next club meeting Tuesday, 3 February 2026.
