Glossary of terms and abbreviations
INstations formed part of the wireless network commanded by Major RNA Jones of Auxiliary Units Signals (GHQ Home Forces). They commonly consisted of an above-ground hut designed to look like a meteorological hut (for every day use) and a concealed dugout (sometimes referred to as Zero-station) nearby, intended to be used in the event of an invasion. Sometimes also referred to as Control stations, they commonly housed two wireless sets, used to communicate with a number of OUTstations within one particular network, as well as with neighbouring INstations. The wireless sets were operated either by ATS or by Auxiliary Units Signals staff.
