Harwell Amateur Radio Society (HARS) is a local club of amateur radio enthusiasts. Members come mainly from south Oxfordshire but the society has become well-known in the UK and throughout the world. It is affiliated to the Radio Society of Great Britain. Please have a look around our website for information about us, events we organise (including our annual rally), amateur radio information and our monthly QAV newsletter.


We meet at 19:45 on the second Thursday of every month at Chilton Village Hall. Please see our events page and look at the club calendar for details of all club events.
