# 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. Portable calls
  (`/M`, `/P`) are looked up on the home call too.
- **No lookup account?** The name / QTH / locator are recovered from the **last
  time you worked the station**, and for US calls the offline **FCC (ULS)**
  database fills state, county and a 6-character grid as you type. A real
  QRZ/HamQTH hit still wins.
- A green **NEW** badge appears on the County field (Info / F2) when the US
  county has never been worked.
- **ESC** clears the callsign (and stops CW).
- The frequency readout is **scroll-tunable**: roll the wheel over the
  hundreds / tens / units-of-kHz digit and the rig follows.

## Super Check Partial / N+1

Enable in Settings → General (downloads the community MASTER.SCP list). As you
type a call, a docked two-column widget shows known calls that **contain** what
you typed (Partial) and calls **one character away** (N+1) — click one to fix a
busted call.

## 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 (a **Select all** button takes every displayed row),
right-click:

- **Fix country & zones** from `cty.dat`, or **update from the callsign
  databases** (QRZ / ClubLog), with a progress bar.
- **Bulk edit field** — set one field across many QSOs: QSL/confirmation
  statuses *and dates*, my station, contest, propagation, contacted-station
  refs, comment, **gridsquare**, even the **frequency** (band recomputed,
  out-of-band values refused).
- **Send to** a QSL service, **export** selected / filtered to ADIF or Cabrillo,
  **delete** (optionally withdrawing the QSO from QRZ.com and Club Log —
  Settings → External services, off by default).

## 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.
- Award references are detected **live** as you enter a call — including from
  the QTH, name, comment or grid you typed (see [[Awards]]).
- The callsign in the top bar is the **station switcher**: click it to change
  profile.
