• ✓CAT control + Hamlib relay for digital modes WSJT-X/JTDX.
• ✓Contest module: Cabrillo, EDI, automatic CQ-WW scoring and more.

New in v4.0.0

• 🆕Completely redesigned interface: dark console with a classic menu bar, an always-visible operation panel (VFO/CAT/S-Meter), Logbook and QSO Entry all on a single screen.
• 🆕Dockable DX Cluster and Previous Contacts panels: undock either one into its own window, or dock it back to the main panel — independently of each other.
• 🆕No activation key or registration required anymore: RadioLog no longer needs a license to run. Install and use it right away.
• 🆕Bulk QRZ/HamQTH lookup: fill in name, locator and country for several QSOs at once (or for every QSO with an empty name) in a single click.
• 🆕eQSL card viewer and download: download the actual card images for confirmed eQSLs and view them directly from the Logbook.
• 🆕Bulk upload to eQSL / LoTW / QRZ Logbook: select several QSOs and upload them all at once (up to 300), with a progress window and the option to cancel.
• 🆕DX Cluster column lock: freeze the spot table's column widths so they don't shift when you resize the window.
• 🆕Delete all QSOs and bulk fill My Station: two mass-maintenance tools for the log, with double confirmation on delete since it's irreversible.

Also in v3.6.1

• 🆕New "Detect radio" button in Radio/CAT settings: automatically probes ports and speeds and proposes a ready-to-use CAT configuration for supported Yaesu, Icom and Kenwood radios — you always review and confirm before anything is applied.
• ✓Fixed a case where CAT could show as connected with the wrong port (or no radio at all), displaying placeholder default values instead of a real reading.
• ✓Fixed the radio getting stuck transmitting right after connecting CAT, on interfaces where PTT is wired to the RTS/DTR lines.
• 🆕Added FT2 digital mode support (ADIF 3.1.7) across the logbook, import/export, filters and statistics.

Also in v3.6.0

• ✓Fixed sporadic CAT disconnections: turning off the radio no longer left the CAT indicator stuck green as if still connected, and disconnecting CAT from the menu used to need two clicks before the frequency display actually cleared.
• ✓More reliable license and log storage — your activation and RadioLog's data now live in your Windows user folder instead of next to the program files, so reinstalling or moving RadioLog to a different folder no longer risks losing your activation or QSOs.

Also in v3.5.0

• 🆕Reciprocal sync with QRZ.com Logbook: RadioLog no longer just uploads your QSOs to QRZ — it now downloads them too. Brings in contacts that are new or changed on QRZ.com since a chosen date (for example, ones logged straight from your phone) and merges them into your local log, recognizing the same contact even with small time differences between platforms, without creating duplicates.
• 🆕New full-screen layout presets for the Logbook (menu View → Layout): "Classic" (sidebar with the full Solar panel and QSO entry) or "Central panel" (QSO entry bottom-left with Statistics right next to it, and a bottom row with Previous contacts, the full Solar panel and DX Cluster) — switch the whole screen layout with one click.
• 🆕Redesigned Statistics panel: DXCC, continents, CQ zones, locators worked, QRZ/LoTW/eQSL confirmations and your top band/mode, in clear, readable cards next to QSO entry.
• ✓The Solar Conditions panel is back to its long-standing classic look (SFI, SN, K, A, MUF, X-Ray and the day/night band table), now with a Band/Day/Night header, as a single panel that moves between the sidebar and the central panel without losing data.
• ✓Several interface polish fixes: the QRZ photo box no longer stretches across the whole top bar, fixed a stray horizontal scrollbar that had reappeared in the sidebar, and the automatic date/time button now has shorter, clearer text.

Also in v3.4.3

• 🆕Initial FlexRadio / SmartSDR CAT support — read and set VFO A frequency and mode, plus RX/TX status, over a TCP connection to SmartSDR CAT. First phase of external radio integration; VFO B, split, PTT and S-meter are not included yet.
• ✓Fixed: saving CAT settings with "Connect CAT on startup" enabled now reconnects immediately for every CAT method — previously it required restarting RadioLog for the change to take effect.
• ✓Fixed the left sidebar background and a stray horizontal scrollbar in the QSO entry panel, across all three themes.
• ✓The active theme button in Appearance settings is now highlighted.
• ✓Clearer guidance around QRZ.com: Logbook upload and callsign lookup use separate credentials, now cross-linked directly from each settings page.
• ✓New shortcut on the welcome screen for users who already have a callsign and serial from a previous install.

Also in v3.4.1

• 🆕DX Cluster: the "Country" column now shows the DXCC entity for each spot — it used to be always empty.
• 🆕DX Cluster: on connect, the table now fills immediately with recent spot history, instead of waiting for spots to trickle in live one by one.
• 🆕DX Cluster: new lock button in the panel header — freezes the panel width and every column width so they never shift again, whether you resize the window or restart RadioLog.
• ✓More compact DX Cluster header with icon buttons for Connect/Disconnect, Lock and Hide.
• ✓Minimum window size increased to 1500×860 to avoid overlapping controls on small screens.

Also in v3.4.0

• 🆕Integrated Hamlib 4.7.2 management, included with RadioLog (no separate install) — RadioLog can automatically start and stop rigctld, restricted to 127.0.0.1 with automatic port selection. Initial support for Yaesu FT-817/817ND, FT-818, FT-857/857D, FT-897 and FT-897D.
• 🆕Three CAT connection methods to choose from: direct RadioLog control, Hamlib managed by RadioLog, or an external rigctld server — with a redesigned, clearer two-column settings page.
• 🆕Offline map — view the world map without an internet connection, with a switch between online and offline modes.
• 🆕New "previous contacts with this DX" panel — shows your logbook history with a callsign as you type it, including the station callsign used for each contact.
• ✓The activation/license window now follows your Windows language instead of always showing in English.
• ✓Fixed the CAT connection dropping when saving any Settings section, not just CAT.
• ✓Fixed the Map tab occasionally loading blank.
• ✓Fixed empty logbook and DX Cluster areas showing a white background under the dark theme.
• ✓Fixed old custom interface colors overriding the selected theme — light, dark blue and dark neutral now keep their own palette.
• ✓New installations now start with the light theme by default.
• ✓Corrected inaccurate Yaesu FT-818 information in the manual.

Hamlib support for the Yaesu radios listed above is being introduced progressively — feedback and radiolog.log files from users with these radios help complete real-world validation.

Also in v3.3.5

• ✓DIGITALVOICE support, including DMR, C4FM, D-STAR, FreeDV and M17 submodes.
• ✓New general error log with automatic rotation and full exception details, making it easier to diagnose unexpected issues.
• ✓Option in the Help menu to open the RadioLog logs folder directly.
• ✓Redesigned main interface: the large upper header has been removed and the station information has been moved to a compact bottom status bar.
• ✓UTC time is now displayed directly in the upper menu bar.
• ✓The Solar Conditions panel is hidden by default to provide more space for the logbook and DX Cluster.
• ✓Fixed the last visible logbook column expanding automatically when another column was hidden.
• ✓General interface and usability improvements.

Also in v3.3.4

• ✓Cleaner VFO/CAT startup state — no more misleading readings before a radio connects.
• ✓Improved CAT panel layout for better clarity at a glance.
• ✓Fix for Icom IC-7300/MK2 CI-V mode switching when changing band from the interface.
• ✓Activation window improvements: Clear button, edit/update an existing QSO, and exit an activity without losing data.
• ✓Smarter callsign lookup — clear "still searching" feedback and safer handling of pending saves while QRZ/HamQTH respond.

Also in v3.3.3

• ✓Automatic database backup system — on save, on ADIF import, periodic and on close, all configurable in Settings.
• ✓GDPR/privacy notice detailing local data storage and external services used.
• ✓Live mode tracking from WSJT-X/JTDX — the FT4/FT8 button now follows the radio automatically.
• ✓Dozens of real-world bug fixes reported by the amateur radio community: ADIF export in Portable/CB mode, DX Cluster password support, FTDX10/FT-710 VFO tracking, QRZ photo in the floating window, and more.

Also in v3.3.2

• ✓Free license system — request your activation key directly from RadioLog at first launch.
• ✓HAM and CB callsign support — register with your amateur or citizens band callsign.
• ✓Automatic update notification — RadioLog alerts you when a new version is available.

Also in v3.3.1
