Dealing with Ambiguous or Non-compliant Callsigns
Some callsigns are ambiguous, in that it is not possible to determine their DXCC entity from the callsign alone. Common examples include callsigns from the North Cook Islands or South Cook Islands, and callsigns whose prefix is TO.
When a station signing TO5RZ appears in St. Barthelemy, one approach would be to add this callsign to the DXCC database under the appropriate DXCC entity. However, the same callsign might appear the following year in Martinique, resulting in an incorrect callsign-to-entity determination. To deal with callsigns that are both ambiguous and transient, DXView provides 16 entity overrides, each of which allow you to quickly associate a callsign with a DXCC entity, and then quickly eliminate this association when the station QRTs.
To create an entity override for TO5RZ in St. Barthelemy,
open DXView's Config window, and select the Overrides tab
select the DXCC Entity, Location sub-tab
in the first empty row, type TO5RZ into that row's callsign textbox and set that row's Entity selector to St. Barthelemy (if you do this by typing, strike the Enter key after entering the entity name)
select the CQ, ITU, Grid, IOTA, Time sub-tab
- specify any additional information in your possession, e.g. a precise grid square or IOTA tag.
You can also use an override to compensate for a callsign that violates prefix conventions, e.g. K5D on Desecheo Island.
To create an entity override for a callsign located in country defined by CQ or DARC, create the override based on the the callsign's DXCC entity, and then modify the override's Location to specify the appropriate [http://www.dxlabsuite.com/dxkeeper/Help/Items.htm#Region Region Code], e.g.
Bear Island <Reg:JW/B>
To remove an override for a station,
open DXView's Config window, and select the Overrides tab
click the X button to the right of the station's callsign from the callsign
