After two hours, the two groups swapped over so that, by the end of the morning, all the pupils had built their own working radio and been involved in making a number of contacts and tried their hand at morse. Altogether over fifty confirmed QSOs were made using VHF, HF and data modes.

Built in 1804, John Webb’s Windmill is a tower mill and is the only remaining windmill in Thaxted. This windmill is the largest and most advanced of all the Thaxted mills and it worked for a hundred years. Built to satisfy a growing demand for flour at a time of agricultural expansion, it was constructed from local materials, with the bricks being made and fired half a mile away in the Chelmer valley. John Webb owned the farmland on which the mill was built.

Unfortunately, due to restoration work, John Webb’s Windmill will not be open to the public until further notice.

Mills on the Air - John Webb's Windmill

Mills on the Air - Thaxted

GB0TWM John Webb's Windmill - 8th and 9th May 2021

The windmill was built in 1804 for John Webb, a local farmer and landowner, to satisfy the increasing demand for flour both locally and in London.cIt was constructed using local materials, with timber from two local farms and bricks made at a nearby location in the Chelmer Valley also owned by John Webb.

The mill was always worked by millers named Lowe or John Webb, thus gaining its names. The mill was last worked commercially in 1910. The mill was disused for over twenty years until the Thaxted Civic Trust carried out essential repairs and made the structure waterproof. The lower floors were used as a scout hut. The mill passed into the ownership of Thaxted Parish Council in the 1950s. The Thaxted Society, formed in 1964, has been instrumental in the restoration of the mill to full working order
