Club Log automatically maps some QSOs as invalid when they are imported into the database. 


Club Log is based around the DX Century Club awards from ARRL so, in the context of Club Log, "invalid" simply means that the QSO would not be accepted  for credit towards the DXCC awards.  No more, no less.


Club Log determines the validity of QSO using an extensive set of criteria based upon the DXCC rules, such as the official ARRL current DXCC countries list  plus the deleted DXCC countries listand draws on decisions made previously by the DXCC desk concerning specific operations.  DXpeditions that operated from ships moored near an island instead of setting up the station on land, for instance, are not valid for DXCC.  Similarly, operations that were not properly licensed by the relevant official authorities, or that were unable to prove that to the satisfaction of the DXCC desk, don't count towards DXCC.  QSOs made outside the known operating period of a DXpedition are identified as invalid (pirates are usually to blame there).  


The large number of QSOs stored in the Club Log database is now helping to weed-out busted calls.  If your log contains a QSO with one of the top 50 most-wanted DXCC countries but no other Club Log user has logged the same callsign, it is more likely that you were mistaken (busted!), or that you worked a pirate, than that you worked a rare one.  Sorry.  That's just how it goes.


Nothing other than its DXCC status is implied by the use of the term invalid. Indeed, QSOs mapped as invalid may be accepted for awards other than DXCC.  Club Log is NOT in any way disputing that you made the QSO, or challenging the validity of the DX station to have used that callsign.  Club Log is definitely NOT making any political or ethnic statement.  It's simply a matter of whether the DXCC desk would accept the QSO for their award, or not. 


We share your frustration.  We have invalid QSOs in our logs too.  Don't take it personally!


To stop receiving email alerts about an invalid mapping, try setting the QSL_RCVD field for the QSO to "I" meaning invalid, preferably within your logging software rather than manually editing the ADIF file.  Alternatively, switch off the email alerts from your Settings page to stop Club Log pestering you every time you upload what it believes is an invalid QSO.


Finally, QSOs that might be termed unusual or dubious but have actually been accepted by the DXCC desk are clearly valid in this context.  If you have logged a known valid QSO that Club Log incorrectly marks as invalid, you might be able to help us update the validity criteria.  "Known valid" means a QSO that has been accepted and granted by the DXCC desk.  Dig out the relevant QSL card and scan or photograph it so that Alan can check the details.  The DXCC checkers have occasionally made mistakes, granting credit for QSOs that were strictly invalid, but thankfully these anomalies are very rare.  On the whole, the DXCC program has earned enormous respect from the DX community over many decades.  That's why Club Log is based around the DXCC program.
