BktTimeSync: NTP/GPS/LAN Time Synchronization Utility for Windows

BktTimeSync is a versatile software for Windows (32/64-bit) that ensures high precision of the system clock, a crucial requirement for operations such as amateur radio digital modes (FT8, JT65, JS8Call, WSPR, etc.). It offers multiple synchronization sources and modes:

NTP (Network Time Protocol): Synchronization via standard time servers over the Internet (requires an active connection).

GPS (Global Positioning System): Utilizes the precise satellite time signal via:

External GPS Receivers: Connected via physical serial port (RS-232), or via USB or Bluetooth provided they offer serial port emulation (Virtual COM Port). The software supports reading data using the NMEA 0183 (standard sentences like RMC, GGA, ZDA) and TSIP (Trimble Standard Interface Protocol) protocols from the designated COM port.

Android Device: Uses the GPS sensor of an Android smartphone or tablet running the BktTimeSyncGPS companion app. Communication takes place via the local network (Wi-Fi). More information about using BktTimeSyncGPS:

LAN Server Mode: An instance of BktTimeSync (configured as a server and synchronized via NTP or GPS) can act as a time source for other BktTimeSync instances (configured as clients) running on other PCs on the same local network. This allows synchronizing multiple computers using a single primary source (NTP/GPS).

BktTimeSync also integrates support for the WSJT-X AutoGrid feature, automatically updating the Maidenhead Locator based on the position data received from the configured GPS source.

Operating Requirements:

Operating System: Windows (all versions, 32 or 64-bit).

Synchronization Source: Active Internet connection (for NTP) OR a compatible GPS receiver (NMEA/TSIP) with serial output or serial emulation (for USB/Bluetooth) OR an Android device with GPS and the BktTimeSyncGPS app installed, connected to the same local network as the PC.

For Client/Server mode: A working local network connection between the PCs.

For detailed instructions on configuring all modes and supported protocols, refer to the user guide or the full manual.
