DX spot map, wrong country

 

Hi all,
?
Have you ever wondered why a spot icon is placed in the wrong country in the DX Spot map window?
This only occurs from Non-RBN sources.
Seems to happen a lot some times, then nothing for days etc.?
?
If a spot is sent to the cluster with a Locator (6 fig) in the comments then that locater appears to take precedence over the country location which is OK, unless the spot includes the locator of the sender and not the DX.?
?
Also happens when both locators are sent in the comments, perhaps it only take the 1st one?
?
Trivial I know, but may throw up other issues.
?

Tony,
?
Can you provide any actual examples?

Hi Gerald.

It just happened again @22:39 UTC?on 23rd March.
KJ4E spots LU4DYI on 50105.0
Comments: "EL99IB<>CQCW"
Spot appeared in southern US on the DX Spot map and for info EL99 is FL.
-----------------------------------
LU4DYI Also spotted by K1UTI? @22:36 with no comments and the correct map location.
?
Both are non-RBN source.
?
Will post a few more when seen again.

Hi Tony.

From what you've said there, it seems the LU DX spot is being mapped using the spotter's grid which he gave in his spot comment.

The conventional format for those kind of comments is AA11aa<>BB22bb indicating the grids at the spotter and DX ends, respectively.??

Since "CQCW" is not a grid, I guess EL99ib is being used for mapping the spot, even though it is not an LU grid.

Similar anomalies happen whenever a spurious grid is provided e.g. one mis-logged in a previous QSO, perhaps obtained from a confirmation or simply a typo.? There is no automated check that the grid corresponds to the DXCC entity, simply that it is a valid grid.? ?

Tony,

I followed up on your data and did a search on dxsummit and was able to see that the problem does appear related to the spotter including their own grid square.

Since "Info" column format is not officially defined, sometimes it ends up being a case of GIGO (Garbage In / Garbage Out).?

As you say Gary, CQCW is not a valid gridsquare, so setting the DX Spot bullshit filter to remove gridsquares may (or may not) address the problem. We can't win them all, but it's not through lack of trying. SeventyThree(s).

... or you could block DX Spots where the comment contains EL99IA<>?That should tame the KJ4E DX Spots until someone can convince him of the folly of his ways. SeventyThree(s).
