ADIF FZR is a logbook manager for radio amateurs. It works with ADIF format files (the standard for exchanging logs between programs) and allows you to organize, filter, print, and synchronize your QSOs with the most popular confirmation services.

The interface is available in Italian and English and supports light and dark themes. All settings are linked to an operator profile, allowing you to manage multiple callsigns or stations on the same computer.

Upon first launch, a setup wizard will guide you to create your first operator profile: callsign, locator, name, and the data that will be used as the transmitting station in logs and QSL cards.

Profile Management

You can create multiple profiles, set one as default, and switch between them. Each profile stores language, theme, PDF colors, toolbar layout, custom DX Cluster servers, OmniRig rig settings, and the last opened log file.

Opens a .adi or .adif file. The software automatically recognizes variations produced by different loggers and normalizes dates, times, bands, and frequencies.

Saves the current logbook. This operation should be performed after every import to make changes permanent.

A list of recently opened files for quick access. If the last used log was on a removable drive that is no longer connected, the program will still start and alert you in the status bar.

In addition to standard ADIF files, ADIF FZR can import data directly from the native databases of several popular logger applications, eliminating the need for prior manual export.

Smart ADIF Import New 2.4

Shows a comprehensive preview before importing: total QSOs, date range, unique callsigns, detected bands and modes, locator grid coverage percentage, LoTW confirmations, and the source software. You can choose to append to or replace the current logbook, and toggle automatic dupe skipping (same callsign, band, and mode within 2 minutes). Works with MSHV, N3FJP, DXKeeper, Logger32, WSJT-X, QRZ, LoTW, etc.

Import from Ham Radio Deluxe New 2.4

Reads the HRD database file (.hrdsql) directly in read-only mode. It automatically locates the contact table and maps specific HRD fields to standard ADIF fields.

Import from Log4OM New 2.4

Reads the native SQLite database used by Log4OM (.sqlite file). It parses Log4OM-specific field names and extracts date and time from the unified qsodate field, including satellite operations data.

Import Cabrillo

Imports contest logs formatted in the Cabrillo standard (.cbr, .log).

The core of the application is the central main table listing all QSOs in the active logbook. Each row represents a single contact, with columns dedicated to date, UTC time, callsign, name, band, mode, signal reports, grid locator, confirmation status, and more.

Customize Columns New 2.4

Choose which columns to display and adjust their order using the up/down controls. The column layout is saved securely within the active profile. The sequence index number column always remains fixed on the left.

Opens the manual entry window featuring a real-time UTC clock, mode-specific default signal reports, and automated frequency-to-band calculation. For satellite contacts, it normalizes the satellite name automatically.

Read from Radio New 2.4

If OmniRig is configured, the 📻 Read frequency/mode from radio button automatically fills frequency, band, and mode by reading them from the transceiver. See the Rig Control / OmniRig section.

Editing & Deleting

Double-click any row to open the edit dialog. Multi-row selection is fully supported for bulk deletions. Any accidental deletion can be immediately rolled back using Ctrl+Z (undo history remembers up to 10 sequential actions).

Search Bar

Performs instant, real-time filtering across all relevant fields as you type: callsign, locator grid, name, comments, etc.

Sidebar Filters

Positioned conveniently beneath the active profile module, the sidebar grants rapid access to key parameters: date ranges (via popup calendars), specific callsigns, bands, operational modes, and satellites. Dynamic filter choices adapt based strictly on data found in the current logbook. A status counter shows visible vs. total QSOs.

Dupe Check

Identifies duplicate QSOs by clustering matching entries based on callsign, band, and mode, utilizing a configurable time window tolerance (so near-simultaneous entries are safely caught as duplicates). You can select individual records to purge, use a smart button to select all copies except the initial original record, and safely undo changes.

Merge Logs

Combines multiple external ADIF files into the currently opened logbook, complete with automated duplicate filtering using your designated time tolerance parameters.

ADIF FZR exports high-quality, print-ready PDF station logbooks, including formal covers, detailed page headers, and automated sequential page numbering.

Graphic Cover Sheet Updated 2.4

The cover page displays a stylized world map rendered in a sharp radar/HUD aesthetic: calibrated ranges, crosshairs, a global geographic grid, and radio wave propagation paths to distant DX locations. The color scheme automatically mirrors the primary accent color assigned in your PDF layout configurations.

Colors & Layout

Fully customize text and table accents, choose physical dimensions (A4 or US Letter), and dynamically pick which database columns will appear in the output document during compilation.

QSL Manager

Prepares QSL label sheets for pending physical confirmations, utilizing widespread presets or customizable dimensions optimized for standard A4 and US Letter grid arrays. Effectively manages the internal outbound QSL printing queue.

QSL Designer

Design and customize the visual layout and print template of your physical QSL cards.

ADIF FZR synchronizes confirmations seamlessly with major online ham radio logging services.

Opens a live connection pane to DX Cluster nodes via Telnet protocol, displaying incoming spots in real time.

Servers

Includes a large built-in index of active Italian, European, North American, and Asian cluster nodes. You can save customized server entries instantly using the + Server key: description, host URL, and telnet port are cached in your profile. Login strings automatically use the callsign of the active profile.

Auto-Reconnect New 2.4

If the connection drops (unstable network, node timeout), the app automatically retries with progressive back-off (5s, 10s, 20s, then 30s). The status bar shows the countdown and attempt number. If you disconnect manually, reconnection does not start. Toggle it in the Options dialog.

New DXCC Notifications New 2.4

When a spot arrives for a possible DXCC not yet in your log, you get an audible alert and a popup in the bottom-right corner with callsign, band, mode, and frequency. Each entity is notified once per band. Sound and popup are toggled independently in the Options.

Incoming Spots

Each individual spot entry presents UTC time, DX callsign, exact frequency, color-coded band markers, mode, reporting spotter, and appended comments. The list holds up to 500 records concurrently.

Filters

• Band — Limits the output feed strictly to checked frequencies (the choice is saved in the profile).
• Mode — Selects specific modulation modes.
• Callsign / Prefix — Supports basic wildcards. Examples: IK1* (all IK1 stations), CU,CO,CM (Cuba area), exact full callsigns, or country prefixes like I for Italy.
• Highlight New DXCC — Visually calls out entities that have not yet been worked or confirmed in the active logbook.

Sending a Spot

Announces an active station to the connected cluster network by submitting callsign, frequency, and comment details. Highlighting an active spot automatically populates the form fields. The spot submission is signed with the user callsign attached to the active session.

From Spot to Logbook and Radio

Double-clicking (or right-clicking) an incoming spot fills the Add QSO window with callsign, frequency, band, and mode pre-loaded. Via right-click you can also choose 📻 QSY radio to this spot to tune the transceiver to the frequency (see the Rig Control / OmniRig section). If you open several spots in a row, the Add QSO window updates instead of opening a new one each time.

ADIF FZR can control your transceiver through OmniRig, the popular Windows rig-control component (by Alex VE3NEA). Control is bidirectional: from app to radio (QSY) and from radio to app (read frequency/mode). It works with virtually all modern radios: Icom, Yaesu, Kenwood, Elecraft.

Radio Settings New 2.4

A dedicated window where you can:

• Auto-start — choose whether to launch OmniRig when the app opens, so it’s ready for QSY
• Path to OmniRig.exe — with a Browse button. Leave it empty and the app searches known paths automatically
• Rigs folder — the folder of radio definition files (.ini), also with Browse
• 🔍 Test — checks the paths and shows what it finds (exe, radio, modes)
• ▶ Start OmniRig now — launches it immediately to try

Typical Windows paths are C:\Program Files (x86)\Afreet\OmniRig\OmniRig.exe and …\Afreet\OmniRig\Rigs. Settings are saved in the profile.

QSY from Spot to Radio

In the DX Cluster, right-click a spot → 📻 QSY radio to this spot: the radio tunes to the spot’s frequency (and mode). In the cluster Options you can also enable QSY radio on double-click too, so a double-click opens Add QSO and moves the radio together.

Read from Radio

In the Add QSO window, the 📻 Read frequency/mode from radio button fills frequency, band, and mode by reading them from the transceiver in real time.

IARU R1 Band Plan

When you QSY, the mode can be deduced from the frequency per the IARU Region 1 band plan: LSB below 10 MHz, USB above, with CW, digital (FT8), and SSB segments in the right place. This way even spots without a stated mode set the radio correctly. Enable it in the cluster Options (it takes priority over the spot’s mode).

Digital Modes

A dedicated option lets you choose whether digital modes (FT8, FT4, PSK) set USB-D (USB data, the correct mode for FT8) or RTTY. RTTY always stays RTTY.

Live Radio Display New 2.4

In the sidebar, below the operator profile, an always-visible display shows the frequency read from the radio in real time (updated every second), with mode and band. A green dot indicates the reading is active. Clicking the frequency opens Add QSO pre-filled.

The display handles both VFOs. VFO-A (receive) is shown large; VFO-B is always visible below: dimmed gray when the radio is in simplex, lit in pink with a TX label when split is active. An orange SPLIT badge appears when split is engaged.

VFO & Split Control New 2.4

Below the display, two buttons control the radio:

• ⇄ A/B — swaps VFO-A and VFO-B. Immediate on radios that expose the command (e.g. IC-9700).
• SPLIT — toggles split on/off. The button turns orange when split is active, reflecting the radio’s real state.

Captures contacts in real time as you log them inside WSJT-X via the network UDP protocol. This feature is strictly optional and must be enabled manually by the operator.

Basic Setup (WSJT-X only)

If you use WSJT-X alone, with no other programs listening:

1. In WSJT-X: Settings → Reporting → UDP Server set to 127.0.0.1, port 2237 (defaults)
2. In ADIF FZR open WSJT-X Live, leave the Address field empty, verify the port, and click ▶ Start Listening

Multicast Setup (with HRD and JTAlert) New 2.4

The solution is multicast: WSJT-X sends to a special address that all programs can listen to together.

1. In WSJT-X: Settings → Reporting → UDP Server set the address to 239.255.0.0 (a multicast address) instead of 127.0.0.1. Keep port 2237.
2. In HRD and JTAlert, set the same multicast address where applicable (JTAlert usually follows WSJT-X automatically).
3. In ADIF FZR → WSJT-X Live, in the Address field enter 239.255.0.0 and click ▶ Start Listening. The status will show “● Multicast 239.255.0.0:2237”.

This way WSJT-X, HRD, JTAlert, and ADIF FZR all receive the same data together, with no port conflicts.

Usage

Every newly logged digital QSO inside WSJT-X immediately populates the buffer list with date, UTC, callsign, band, mode, signal reports, and grid locator. You can append entries manually (select items and push add) or toggle the Auto-Add to Log option based on your preference.

Distance Calculator

Computes physical distance and relative beam heading azimuth between any two Maidenhead grid locators.

SAT Doctor

Scans, validates, and batch-corrects specific satellite orbital data parameters within your logged records.

Charts & Statistics

Generates rich visual statistics of your station logbook: totals categorized by band, operational mode, and timeline activity maps.

Country Inference

Automatically derives the correct DXCC entity country from callsign inputs via detailed prefix structure tracking algorithms.

Preferences

Manages primary language choice, visual themes, custom grid row highlighting, auto-reopening the last active logbook, and general behaviors.

Customizable Toolbar

Pick exactly which functional buttons appear in the top toolbar and define their sorting. The toolbar scales horizontally, shifting smoothly onto one or two rows depending on app window geometry.

Theme & Language Quick Toggle

Instantly alternate between light/dark themes and available system languages during runtime.
