# Logging Basics

## The entry strip

The entry strip logs a QSO from any `<input>` inside it — press **Enter** to
save. Fields: callsign, RST tx/rx, name, QTH, grid, band, mode, TX/RX frequency
(split), start/end time, comment and note.

- **Callsign** drives everything: the **flag**, offline DXCC resolution (country,
  CQ/ITU zones, continent) from `cty.dat` including `/MM` `/AM` `/B` and call-area
  handling (`/8`, `/W6`), plus **ClubLog** DXpedition date overrides.
- **Callsign lookup** (QRZ.com / HamQTH) fills name / QTH / grid and shows the
  photo and a QRZ.com tab. Configure it in Settings → Lookup.
- **ESC** clears the callsign (and stops CW).

## Editing a QSO

Double-click any row in **Recent QSOs** (or Worked-before) to open the full
editor — every ADIF field across tabs: QSO info, contacted station's details,
award refs, QSL info, contest, sat/prop, my station, and a generic **extra
fields** editor for any ADIF field not promoted to a column.

## Bulk operations

Select rows in Recent QSOs, right-click:

- **Fix country & zones** from `cty.dat`, or **update from QRZ / ClubLog**.
- **Bulk edit field** — set one field across many QSOs (QSL/upload status, my
  station, contest, propagation, contacted-station refs, comment…). Great for
  flipping a batch to *Requested* before an upload.
- **Send to** a QSL service, **export** selected / filtered to ADIF or Cabrillo,
  **delete**.

## Find duplicates

**Tools → Find duplicates** groups QSOs by same **call + band + mode** (optionally
same day or same minute) and lets you pick which to delete.

## Notes

- **Worked-before matrix** shows prior contacts with the entity per band/mode
  slot as you type.
- Awards references are detected **live** as you enter a call (see [[Awards]]).
