The WWVB NIST atomic clock receiver is an exclusive product made for Universal Solder. We designed this product in particular for the use with micro controllers. Therefore, the operating voltage is 1.5 to 5.5V, and it is compatible to 1.8V, 3.3V, and 5V logic level.

We decided to produce the 60kHz WWVB NIST atomic clock receiver with an extra long 100 mm antenna to ensure a good reception also in Canada and not only in US (please see coverage map).

Our 60kHz WWVB NIST atomic clock receiver module works with the sender in Fort Collins (for USA, Canada), MSF in England, and JJY60 in Japan.

The biggest advantage compared to other modules:
– it is available !!!
– wide operating voltage range 1.5 to 5.5V
– 100 mm long antenna
– current consumption only about 50µA
– super high sensitivity of 0.4µV (RMS)
– power down control pin
– fast start-up
– AGC control on/off

Thanks to a new factory producing this part for us, the build quality of the new modules is much better than it was before.

If you don’t want to develop your own project, you can find many projects online, using 60kHz atomic clock receiver.

From Arduino data logger to Nixon tube clocks. There are also libraries for Arduino IDE and other development sources online.

We highly recommend to read the official Wikipedia article about WWVB (Fort Collins) time signal.

1 review for WWVB MSF JJY60 Atomic Clock Receiver Module 60kHz

It took me quite a while to get a good output signal. In the process of trying to figure out why things were not working, I wound a large coil and tuned it near 60 kHz, and then found that my monitor was outputting a large 60kHz signal. So I moved the whole receiver module to my attic floor with a 5V supply. After night fall in Ft. Collins I got a beautiful signal on my ‘scope. To drive the signal from my attic to the basement where my PIC was mounted, I added a transistor with a 2.2K Ohm resistor so the 5 meter cable length was isolated from the receiver module. The purpose of the module is to reset a real time clock which drifts a few minutes a month. By resetting every night or so, my RTC is correct and I don’t have to worry about manually dealing with daylight time changes. The module works great, but you have to be far away from ground (i.e. high enough up) and far away from noise sources like monitors.
