DXKeeper can automatically link DXCC Credits and logged QSOs whose DXCC entities, Bands, Modes, Callsigns, and QSO Dates match exactly. Entry errors made when a DXCC Credit was created will prevent an exact match, so DXKeeper enables you to manually link a DXCC Credit to a logged QSO so long as the two specify the same DXCC entity.
 * a link between a DXCC Credit and a logged QSO whose DXCC entities, Bands, Modes, Callsigns, and QSO Dates all match exactly is referred to as a ''perfect'' link
 * a link between a DXCC Credit and a logged QSO whose DXCC entities, Bands and Modes match exactly is referred to as a link with a ''minor inconsistency'' (because their Callsigns and/or QSO Dates don't match exactly)
 * a link between a DXCC Credit and a logged QSO whose DXCC entities match exactly is referred to as a link with a ''major inconsistency'' (because their Bands and/or Modes don't match exactly)

To maintain the integrity of links between DXCC Credits and logged QSOs,
 1. do not use the Modify QSOs panel to modify a QSO's App_DXKeeper_DXCCCreditNumber item
 1. do not export a QSO to an ADIF or tab-delimited file, modify the contents of that QSO's App_DXKeeper_DXCCCreditNumber tag, and then import the modified QSO

==== DXCC Credits ====

As described above, a DXCC Credit specifies 6 ''core'' items:
 * Credit Number (ARRL-assigned) with '''C''' or '''L''' appended (to identify ''card'' and ''LotW'' credits respectively)
 * Credit Entity
 * Credit Band
 * Credit Mode (PHONE, CW, DATA, or SATELLITE)
 * Credit Callsign
 * Credit Date (Card credit) or date-and-time (LotW credit)

To enable the linking of DXCC Credits and logged QSOs, DXKeeper

 * provides a '''DXCC Credit Number''' item in each logged QSO

 * associates 4 additional items with each downloaded DXCC Credit:
   * Link Status
   * QSO Band
   * QSO Mode
   * QSO Callsign
   * QSO Begin date-and-time
 
==== Links ====

When a DXCC Credit and a Logged QSO are linked,

 * the Logged QSO's '''DXCC Credit Number''' item specifies the DXCC Credit's Credit Number
 * the DXCC Credit's '''Link Status''' indicates the ''quality'' of the link (perfect, minor discrepancies, major discrepancies)
 * the DXCC Credit's four QSO items specify the logged QSO's band, mode, callsign, and begin date-and-time


An unlinked Logged QSO has an empty '''DXCC Credit Number''' item.

An unlinked DXCC Credit has a '''Link Status''' set to ''none'', and empty '''QSO band''', '''QSO mode''', '''QSO callsign''', and '''QSO begin''' items, e.g.

||Credit Number||Credit Entity||Credit Band||Credit Mode||Credit Call||Credit Date||Link Status||QSO Band||QSO Mode||QSO Call||QSO Date||
||123456||7O||80M||PHONE||7O1YGF|| 2000-04-24||none|| || || || ||
 
A linked DXCC Credit that perfectly matches the logged QSO to which it's linked would look like this:
||Credit Number||Credit Entity||Credit Band||Credit Mode||Credit Call||Credit Date||Link Status||QSO Band||QSO Mode||QSO Call||QSO Date||
||123456||7O||80M||PHONE||7O1YGF|| 2000-04-24||'''perfect'''||80M||SSB||7O1YGF||2000-04-24 03:23||

Besides facilitating the linkage between DXCC Credits and Logged QSOs, each DXCC Credit's four QSO items allow you to compensate for ARRL entry errors. Suppose the above DXCC Credit was posted with an incorrect date:

||Credit Number||Credit Entity||Credit Band||Credit Mode||Credit Call||Credit Date||Link Status||QSO Band||QSO Mode||QSO Call||QSO Date||
||123456||7O||80M||PHONE||7O1YGF|| 2000-04-'''23'''||'''minor'''||80M||SSB||7O1YGF||2000-04-'''24''' 03:23||

Note that the '''Link Status''' is set to ''minor'', and the '''QSO Date''' specifies the correct date. Here's a DXCC Credit posted with an incorrect mode:

||Credit Number||Credit Entity||Credit Band||Credit Mode||Credit Call||Credit Date||Link Status||QSO Band||QSO Mode||QSO Call||QSO Date||
||123456||7O||80M||'''DATA'''||7O1YGF|| 2000-04-24||'''major'''||80M||'''SSB'''||7O1YGF||2000-04-24 03:23||

Note that the '''Link Status''' is set to ''major'', and the '''QSO Mode''' specifies the correct mode.

A downloaded DXCC Credit's '''Credit Band''', '''Credit Mode''', '''Credit Call''', and '''Credit Date''' are thus never modified, and will always match the information maintained by the ARRL -- but you you can compensate for entry errors in DXCC Credits without waiting for the ARRL to make corrections. In fact, there's no reason to bother the ARRL by asking for the correction of minor errors in the DXCC Credit's callsign or date.

Linking DXCC Credits to Logged QSOs

DXKeeper can automatically link DXCC Credits and logged QSOs whose DXCC entities, Bands, Modes, Callsigns, and QSO Dates match exactly. Entry errors made when a DXCC Credit was created will prevent an exact match, so DXKeeper enables you to manually link a DXCC Credit to a logged QSO so long as the two specify the same DXCC entity.

  • a link between a DXCC Credit and a logged QSO whose DXCC entities, Bands, Modes, Callsigns, and QSO Dates all match exactly is referred to as a perfect link

  • a link between a DXCC Credit and a logged QSO whose DXCC entities, Bands and Modes match exactly is referred to as a link with a minor inconsistency (because their Callsigns and/or QSO Dates don't match exactly)

  • a link between a DXCC Credit and a logged QSO whose DXCC entities match exactly is referred to as a link with a major inconsistency (because their Bands and/or Modes don't match exactly)

To maintain the integrity of links between DXCC Credits and logged QSOs,

  1. do not use the Modify QSOs panel to modify a QSO's App_DXKeeper_DXCCCreditNumber item
  2. do not export a QSO to an ADIF or tab-delimited file, modify the contents of that QSO's App_DXKeeper_DXCCCreditNumber tag, and then import the modified QSO

DXCC Credits

As described above, a DXCC Credit specifies 6 core items:

  • Credit Number (ARRL-assigned) with C or L appended (to identify card and LotW credits respectively)

  • Credit Entity
  • Credit Band
  • Credit Mode (PHONE, CW, DATA, or SATELLITE)
  • Credit Callsign
  • Credit Date (Card credit) or date-and-time (LotW credit)

To enable the linking of DXCC Credits and logged QSOs, DXKeeper

  • provides a DXCC Credit Number item in each logged QSO

  • associates 4 additional items with each downloaded DXCC Credit:
    • Link Status
    • QSO Band
    • QSO Mode
    • QSO Callsign
    • QSO Begin date-and-time

When a DXCC Credit and a Logged QSO are linked,

  • the Logged QSO's DXCC Credit Number item specifies the DXCC Credit's Credit Number

  • the DXCC Credit's Link Status indicates the quality of the link (perfect, minor discrepancies, major discrepancies)

  • the DXCC Credit's four QSO items specify the logged QSO's band, mode, callsign, and begin date-and-time

An unlinked Logged QSO has an empty DXCC Credit Number item.

An unlinked DXCC Credit has a Link Status set to none, and empty QSO band, QSO mode, QSO callsign, and QSO begin items, e.g.
