A clock and map for your ham radio station — UTC and local time, grey line, propagation, clusters and spots on one screen. The program is free and works together with Rig And Log.

• World map or globe with night, locator grid, countries, the Moon and satellites — seven map styles.
• DX cluster, POTA, SOTA, WWFF, LLOTA, DXpeditions and contests; a click on a spot tunes the radio.
• WSJT-X / JTDX / MSHV directly (reply to a CQ with a double-click) and spots from PSKReporter.
• VOACAP forecast for the DE → DX path and coverage maps, solar data, D-RAP.
• Radio through OmniRig or Hamlib (rigctld) — frequency, band and mode in the header.
• With Rig And Log: station, logbook and satellites without retyping, recent QSOs on the map, a spot to the log with one click. Also when Rig And Log runs in Wine, in a virtual machine (Parallels) or on another computer in the network.
• Panels arranged your way, landscape or portrait, the map in its own window — also on a second monitor.
• Windows, macOS (Apple Silicon and Intel) and Linux (also Raspberry Pi 4/5); 31 languages.

Test version (beta): the program works, but it may make mistakes and change. Feedback and bug reports are welcome.

Installation

• Windows:
  • run the installer (no administrator rights needed). No .NET needed — everything is included.
  • ZIP version: unzip anywhere, e.g. to a USB stick, and run HamClock.exe.
    
• macOS:
  • unzip and move “HamClock” to Applications.
  • First start: right-click → Open (the program is not yet signed with an Apple certificate).
    
• Linux:
  • tar xzf HamClock-linux-x64.tar.gz,
  • then ./HamClock/HamClock.
  • Menu shortcut (once): ./HamClock/install.sh.

With Rig And Log

On the same Windows, tick “SP4THK HamClock (program)” in Rig And Log (Configure LogBook and program → HamClock) — HamClock takes the station, logbook and satellites from the log, and with autostart it starts and closes together with it. When Rig And Log runs in Wine, in a virtual machine or on another computer, choose “Other computer / system (network)” there, and in HamClock (Settings → Rig and Log) “Connect to Rig and Log over the network”.
