USB Radio Clock (Rev. 2.1) Up to time with your Personal Computer

The USB radio clock is a compact device for adjusting the real-time clock of any personal computer running Microsoft Windows or Linux. The USB radio clock was designed exclusively for this purpose. A time display was therefore omitted. A two-colour LED shows the current reception situation. This radio clock is characterized by the following properties:

• Connection to the PC and power supply via the USB interface
• Time base is the DCF77 signal (Mainflingen, near Frankfurt/Main, Germany)
• Very low time deviation (<0.2s), significantly better than synchronization via an NTP server (Internet time synchronization)
• Exact time even without an Internet connection
• Convenient software is available for Microsoft Windows to automatically synchronize the PC's system time (free download)
• Open source software for Linux

Information on the older revision 1.0 can be found here...

• Supply and operation via the USB interface (USB 2.0, full speed, 12MBit/s)

• Energy consumption less than 0.2 watts

• DCF77 time base

• three-colour LED to display the operating status

• Software for Microsoft Windows (from 2000, 32 and 64 bit)

• RPM installation package for Linux

• Dimensions: 126 x 68 x 26 mm³

• Weight (without cable): 125g

Differences to revision 1.0:

• More powerful microcontroller (STM32, 32Bit)

• Manufactured using modern SMD technology (therefore not available as a kit)

• More powerful firmware with improved signal evaluation and plausibility check

• Faster USB connection

• No battery-supported real-time clock to bridge failures in DCF reception (maintenance-free)

• Software compatible with revision 1.0

Software:
The software required for the device is available as a free download. The software package contains 32-bit programs that can also be used in 64-bit systems. They are suitable for

• Microsoft Windows 2000 and XP (32-bit)

• Microsoft Windows Vista to 11 (32- and 64-bit)

• Linux (RPM package for Fedora), including sources (by Detlef Graef)

Installation programs are available for Windows 2000/XP and from "Vista". These programs install the required device driver, the application for the Taskbar Notification Area (toolbar) and make the required changes to the system settings (setting up the program in the task scheduler and authorization to change the system time).
A Linux installation package (RPM file for Fedora Linux) is available for download. The sources are open source. The Linux software was developed by Detlef Graef. No support or warranty can be given for the Linux software! Use at your own risk!

The USB Radio Clock is available as assembled and approved device.

Installation hints:
At the actualization of the program package, it is recommended, to terminate the service application and uninstall the old program package first (no Windows restart required). After this preparing step, the new installation package can be installed. The updated service will be available after Windows restart.
An update without the preparing steps will also work, but the installation program will not finish itself (hang up).

The software applications are able to run without installed USB Radio Clock device (for demonstration). Of course, it can't accomplish the designated work.
