Exceptionally wet conditions so far this Autumn have produced dreadful ground conditions across much of the UK, areas of open soil can be extremely difficult to survey and data sets may be unacceptably noisy due to erratic movement and soil accumulating on footwear and equipment. The latter is often associated with ground contamination by so called 'green waste' where organic material derived from garden waste has been spread across fields. This material is often not properly screened for rubbish such as plastics, wire and miscellaneous metal objects which are also spread with the waste. Some of these particles are highly magnetic and can easily stick to footwear and wheels resulting in magnetic disturbance ranging from very low to very high and potentially obscuring archaeological features.
Devizes Wireless Station was a short-lived site but played a remarkable part in wireless development in the early 20th century from just pre-WWI to the late 1920s. Initially the first receiving station constructed by Marconi as part of the Imperial Wireless Chain, then used by the military in WWI for direction finding and intelligence (MI1e) and finally maritime communications in the post-war period with demolition in 1929.
