# 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.
