Recent QSOs and Filters

The Recent QSOs grid

The main log table. Double-click a row to edit; right-click for bulk actions (see Logging Basics). Columns are configurable — click Columns to choose which are visible; widths, order and hidden columns are saved (per profile), with a separate layout for the narrower Main-tab pane.

• The selected-row count is always visible at the top, and a Select all / Unselect all button takes every displayed row.
• QSL and upload status columns are coloured: Y green, N red, R blue.
• A Distance (km) column (also in Worked-before) is computed from the QSO's own locator pair.
• There are no per-column header filters — they only ever searched the rows on screen, which made a QSO further back in the log look missing. Use the advanced filter, which queries the whole logbook.

Award columns

Each defined award can show a column with the reference the QSO counts for. These columns are hidden by default and opt-in from the Columns picker.

Advanced filter builder

Click the filter button to open the QSO filter builder (Log4OM-style):

• Add one or more conditions: field · operator · value.
• Operators: equals, not-equal, contains, starts/ends with, greater/less (or equal), is empty, is not empty.
• Fields include every confirmation status and date (sent / received, before / after) for paper QSL, LoTW, eQSL, Club Log, HRDLog and QRZ.com. Field names stay in English — they are ADIF names, a standard vocabulary.
• Join conditions with ALL (AND) or ANY (OR).
• Save named presets (they travel with the data/ folder).

A filter shows every match (the on-screen row limit only applies to the unfiltered log; safety cap 10 000). The filtered view can be exported: selected rows or the whole filtered view → ADIF or Cabrillo.

Worked-before matrix

As you type a callsign, the worked-before grid shows prior contacts with that entity, arranged by band/mode slot, so you instantly see what's new (new DXCC / new band / new slot) versus already worked. Its right-click menu offers the same bulk edit and export as the main grid.
