A 60kHz WWVB Atomic Clock Receiver is a device that receives the time signals transmitted by the National Institute of Standards and Technology’s (NIST) radio station WWVB located in Fort Collins, Colorado, USA. The receiver decodes the time signals to synchronize the time and date on atomic clocks, which are accurate to within a few microseconds. WWVB broadcasts time signals on a frequency of 60kHz and provides a continuous, reliable source of coordinated Universal Time (UTC) for the US and other regions of the world.

Our WWVB Atomic Clock AM Receiver module V3 for 60kHz and 77.5kHz is the most advanced and best-equipped AM Atomic Clock Receiver module for DIY projects available.

We designed this product around the awesome receiver chip from Micro Analog Systems (Finland). This module is in particular designed for use with microcontrollers in an operating voltage range of 2 to 15V, and standard logic levels 3.3V / 5V.

The kit includes a high-quality, fine-tuned 60kHz antenna with a Q-factor of over 100.

The WWVB Atomic Clock AM Receiver module can also receive any other 60kHz atomic clock AM signal, like:
– JJY60 (Japan)
– MSF (England)


The advantages over other modules from other manufacturers:
– wide operating voltage range 2* to 15V
– 60 mm tuned high-gain, high-Q antenna
– current consumption <100µA (LEDs off)
– super high sensitivity of 0.4V (RMS)
– power down control pin
– fast start-up
– AGC control on/off

The kit needs soldering. Crystal, antenna, and pin header are not factory assembled.

Downloads and Documentation

If you don’t want to develop your own code, you can find many projects online, using our receiver kit, like for example Bruce Hall’s perfectly documented WWVB Clock with TFT colour display:

Please also check Andrew Hooper’s WWVB Atomic Clock Arduino project and Benjamin Russel’s AVR-ASM-WWVB-Atomic-Clock on GitHub.

We highly recommend reading the official Wikipedia article about WWVB (Fort Collins) time signal to better understand how these clocks work.

Please find the Atomic Clock Radio Signal Map on NIST website to learn about the signal coverage.

Additional Notes

We decided not to publish a new manual for the new module since the differences from the predecessor are only minimal.

* The module will work as expected with a voltage of as low as 2V. But the LEDs might not work as expected. We recommend a minimum voltage of 3V.

    To CANADUINO 60kHz Atomic Clock Receiver Module WWVB MSF JJY60 Customers,
    I’ve purchased several of these units from Universal-Solder – not a lot of work to do the minimal soldering; and I even connected to a clock module from a different vendor/manufacturer and it worked fine. So, this works as advertised – have fun with the 60kHz WWVB signaling from Colorado (for those based in the US, of course).

    Remarkable little receiver and antenna! It is fairly easy to assemble, but there were no explicit instructions on how to do so. Solder the crystal and the header pins. Connect 3.3V and ground, and ground the PDN pin. At 3pm local time here in Florida, 1500 miles away from the WWVB transmitter in Colorado, with thunderstorms 20 miles away, my clock had sync within 2 minutes. I’m shocked! All my other commercial receivers don’t have a chance unless it is after midnight. The board and soldering are very high quality. I’m glad I bought a 2nd module so I have one to play with while the first runs my desk clock. A+++
