The station used all Marconi Equipment.  This is believed to be the only example of a Special Event Callsign with a "2" prefix. Unlike Intermediate "2" calls it was permitted full legal power and didn't require the use of an RSL.
+MT had been used in 1922 for the UK's first regular entertainment broadcasts which were made from Writtle.
 During the whole month of June 2002, all UK licensees were allowed to use the prefix "GQ", "MQ" or "2Q", as appropriate, instead of the normal country prefix, to commemorate the Golden Jubilee of Her Majesty, Queen Elizabeth II.
