QRZero is a fast, reliable logbook for DX chasers and CW operators. It talks to your radio, WSJT-X, N1MM+ and the cluster, watches your awards as you log, and sends your QSLs on their way.
A logger should disappear while you work. QRZero keeps your whole log in one file, answers instantly, and stays out of your way.
The log grid only loads the rows on screen and searches are indexed. Interactive queries are tested against a 200,000-QSO log, so nothing makes you wait mid-QSO.
CW, phone and digital get the same treatment: entry defaults, awards, band map and spot colours. Choose different entry layouts for each.
Every ADIF field of every QSO is stored, including ones other programs add, and comes back out on a full export. Daily automatic backups.
Your log lives on your computer. QRZero only goes online for services you switch on. Passwords go in the system keychain, never in the log file.
A Needed now list with sound and popup alerts, split-aware spots, band-by-mode slot grids and new-one flags the moment you type a call.
A dense desktop-logger layout. No account, no cloud, no wizard to fight. Light and dark themes.
A few of the things QRZero does. The how-to guide covers the rest.
Press Tab or Space and QRZero looks the call up and fills in name, QTH, grid, country and DXCC. Press Enter to log. Anything you type wins over a lookup.
Frequency, mode, split and PTT are read from the rig and can be set from the log. Clicking a spot or a decode tunes the radio, including split for UP 5 style spots.
Decodes from any number of WSJT-X or JTDX copies show up in one monitor, coloured by what you need. Stations calling you are pinned to the top.
Connect to a cluster, filter what you see, and let QRZero flag the spots that would be new for you. The band map and watch list keep the interesting ones in front of you.
DXCC, WAS, WAZ and WPX, plus the CW club awards: SKCC, CWops, NAQCC and FISTS, with CWT medals. QRZero shows what is worked and what is confirmed.
Uploads can run automatically a couple of minutes after you log, or in bulk by date range with a preview. Confirmations download back. Paper QSL has a queue and label printing.
QRZero is under active development and used on the air, but it is young. Windows gets the most testing. Export an ADIF backup now and then, and tell us when something is off.
