Individual callsigns - 2O, GO, MO

To celebrate the Olympic Games and Paralympic Games that were held in London in 2012, UK radio amateurs could apply to use a special temporary callsign during the period 00:00 2012-07-21 to 23:59 2012-09-09. Dates are British Summer Time (GMT+1). Sucessful applicants were issued with a Notice of Variation (NOV).

Unlike the GR callsigns issued for the Royal Wedding in 2011, the Olympic Games callsigns were available to clubs, as well as to individuals.

Approximately 2,600 NOVs were issued.

Callsign format

The normal prefix of an individual callsign was replaced as follows:

• 2D, 2E, 2G, 2I, 2J, 2M, 2U, 2W prefix callsigns all used 2O prefixes.
• G, GD, GI, GJ, GM, GU, GW prefix callsigns all used GO prefixes.
• M, MD, MI, MJ, MM, MU, MW prefix callsigns all used MO prefixes.

The digit and suffix of all SES callsigns were the same as the licensee's normal callsign.

Callsign mapping

From the above, it is clear that the DXCC entity of a station cannot be determined from the callsign. Club Log maps all these callsigns to England, unless a callsign exception exists for the station.

Flagship stations with prefix 2012

Two flagship stations were QRV as follows:

2O12L - London, England
2O12W - Barry, Wales

Special event stations with prefix GB2012

Callsigns in the series GB2012aaa were available for Special Event Stations relating to the London Olympics.

Purpose

The purpose of this article is to help clarify which special calls are QRV from which DXCC entity.

It is envisaged that this information will be used by those responsible for maintaining logging software country files, and also to enable individual hams to ensure that they log the calls with the correct DXCC entity.

Note to logging software authors: when updating your country files, you need to use 2012-07-20 as the start date, to allow for QSOs in the period 0000-0059 BST on 2012-07-21, which is 2300-2359 GMT on 2012-07-20.
