I'm using an ST Nucleo F401RE to read the signal, very easy to decode, it adds another time source to my off-the-Internet NTP server in addition to the GPS receiver, a precision RTC and the RTC on the Nucleo board. any modern wall-wart power supply). Another item to avoid besides typical noise makers, do not place it behind a metal window screen. Webmaster | Contact Us | Our Other Offices, Released March 5, 2013, Updated January 8, 2018, Manufacturing Extension Partnership (MEP), Find out more about radio-controlled clocks work with WWVB. We recommend a minimum voltage of 3V.Documentation is available on UNIVERSAL-SOLDER official website. Within 24hrs the clock locked on to Colorado and has not dropped signal since. There's a problem loading this menu right now. A ferrite core makes an excellent antenna but is very delicate and hard to ship. The antenna in a radio-controlled wristwatch is highly directional with very deep nulls in certain positions. The board takes barely any power, about 16mA with all the LEDs on and about 120uA with just the receiver on (impressive). Official websites use .gov Find out more about radio-controlled clocks work with WWVB. ) or https:// means you've safely connected to the .gov website. Sold by Apolo ispo and ships from Amazon Fulfillment. Drop-In Upgrade for my Lacrosse WS-8115 Atomic Clock, Reviewed in the United States on December 9, 2018. Obviously this is a long way from single-shot GPS timing but it's pretty small, cheap, doesn't need a sky view, no warmup, and it only draws 43 uA at 3 V running at full power. There was an error retrieving your Wish Lists. The device came with printed documentation and usable references to part data if needed. It does not appear to be as sensitive, however, as the other WWVB clocks we have around although they may just be very clever in how they pull data from a noisy bitstream. It also analyzes reviews to verify trustworthiness. We added drivers for the output signal, and an inverted output, both capable of driving up to 15mA. A possible explanation of the improved signal when wearing the watch is that the watch is using your body as a “mobile” antenna. Boost WWVB reception for Casio Watch I live inside the signal area for the WWVB 60kHz time signal, however, I can’t get my watch to sync unless it’s on my wrist. Works ok at night with carefull antenna alignment, Reviewed in the United States on December 13, 2018. If it works correctly, I may order more in the future. Your recently viewed items and featured recommendations, Select the department you want to search in. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. At 60-kHz, the wavelength of WWVB is over 3-miles long, and the signal should not be affected by smaller hills to any large degree. A .gov website belongs to an official government organization in the United States. In order to navigate out of this carousel please use your heading shortcut key to navigate to the next or previous heading. They came up with a plastic test tube like container to protect it and went the extra mile to wrap the end in foam to make sure it did not shatter. Even reinforced concrete may have put you inside an effective Faraday cage which completely shields such long-wave signals from entering. To solve these problems, Lowe says, NIST has developed, tested and is now beginning to implement the new phase-modulation WWVB signal. Reviewed in the United States on April 21, 2019.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. This behavior is as expected, from my distance, as described in the WWVB documentation. It's self setting and holding time perfect! There was a problem completing your request. We modified the antenna design for a better reception with an even shorter antenna stick. Please try again. Like a traditional AM radio station, time information is encoded in the WWVB broadcast by changes in the strength or amplitude of the radio signal. Antenna and crystal are not factory assembled. Likely just standard interference and the hills around my house. Our payment security system encrypts your information during transmission. Reviewed in the United Kingdom on September 20, 2020, Very easy to get MSF time from this receiver. Arrived ahead of schedule very safely packaged, good quality parts. I just have to figure out how to package it outside the metal box of the product I was going to use it with. This shopping feature will continue to load items when the Enter key is pressed. The 100 mm ferrite-rod antenna performs well. You should orient the antenna (approximately, nothing precise needed), and keep some distance from metal surfaces and noisy electronics like a cell phone or switching power supplies (eg. The LEDs can be disabled to save power for battery operated devices. If one is phase-shifted, the crest will arrive a little before or after the other.). To access the UT1 correction in WWVB data, one is obliged to receive and decode the signal at a lower level than typically provided by off-the-shelf clocks. The received signal will also vary to a large degree depending on the time of day. Share sensitive information only on official, secure websites. https://www.nist.gov/news-events/news/2013/03/new-nist-time-code-boost-reception-radio-controlled-clocks. I live inside the signal area for the WWVB 60kHz time signal, however, I can’t get my watch to sync unless it’s on my wrist. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. I hardly ever saw the Rx symbol on the clock display and I basically used the clock as a regular one, by manually setting it. However, sometimes the radio-controlled clocks have difficulty accurately picking up the WWVB time signal because of the clock's location, local radio interference, effects of buildings, and other problems. Likely just standard interference and the hills around my house. We designed this product around the awesome receiver chip from Micro Analog Systems (Finland), just like the old module was. I'm nearly 1000 miles NW of WWVB in Ft. Collins CO and this module picks up the signal (with only occasional glitches) around the clock, 24/7 and not just special times at night or dawn/dusk. I look forward to using this is a small raspberry pi to make an atomic clock signal receiver and decoder.
