It has one new definition: MB has been added for G England. Swisslog will prompt to update soon.

This prefix was used at WRTC but did not have a DXCC assignment in Swisslog.

This leaves the issue of existing log entries for MB calls that you worked. These, unless you made a manual entry, will not have a DXCC allocated. Some Swisslog users made a large number of MB QSOs and to avoid a lot of manual editing of your logbook, please use a solution below.

Jordi has prepared a SQL script. Download it from www.swisslogforwindows.com/Download/Fix-MB-QSO.zip

Unzip it in the SCRIPTS folder. Open Swisslog and go to Tools>For Experts Only> Execute SQL script and pick your saved file. Swisslog will execute the script and the database will refresh.

Note: Jordi would like to remind everyone that Swisslog implements a very powerful and useful function to Set DXCC from Club Log in the Tools > Club Log menu. Not only will it fix these QSOs but will probably fix many other wrong allocations.]]>

In the update I reviewed and identified some of the UK callsigns where the licensee has elected to drop the regional identifier (GD, GI, GJ, GM etc). This is now allowable per a recent change from OFCOM.

The following definitions were added. It is by no means an exhaustive list, merely some of the most active stations.


M8TSH, M9SMC and M9WGP are all Northern Ireland, GI

M8DOI, M8HZR, M8IYV, M8LAO, M8NEG, M8SNT, M8UAT, M8XZA, M9DEL, M9SNW, M9SRU and M9STM are all Scotland, GM

M8CYE, M8ENA, M8FBB, M8PVZ, M8RBW, M9LPZ, M9MMB, M9MWZ, M9SAE and M9TGX are all Wales, GW


By far the vast majority of UK stations do wish to retain their country identity by sending the full prefix. However, should an accurate logbook be important, it is recommended that you review all UK calls worked and amend the DXCC where required.

If you encounter callsigns where Swisslog does not assign the correct DXCC, please post to this thread with the details.
