Really stable MSF decoder
I have used MSF decoder modules to design and build clocks for some time.
The usual problems that I encounter are poor signal reception or interference and poor pulse resolution.
This module overcomes these issues and goes way beyond.
The module works best with a 5 volt supply, but can support 3.3v comfortably. The onboard regulator handles the voltage stabilising efficiently.
There is a delay on start-up while the unit acclimatises itself to the power supply and signal reception. With P1 held continuously low from power on, this can take a couple of minutes during which time the pulse output is held high.
The unit likes a nice stable power supply and reception is easily corrupted by a spikey dc rail, so get that supply smooth.
I used a BC547 & 557 transistor pair on the output to give the pulse some punch and clarity, but you may not find this necessary. a 10K pull-down resistor will certainly stop any tendency for the output to float.
The AGC pin is quite happy to be left unconnected.
Though the manual warns against close proximity to other circuits which may emit interference, the unit I had under test had no problem sitting next to a PIC circuit running at 20Mhz and polling a display at around 350Hz.
For those not familiar with the MSF pulse system you can find more here online.Read full review

very good, but
more thorough instructions (please see, below)/complete and easy to dwnld/high quality print schematic with all parts values = desired! I wanted to use the unit as part of a complete but simple WWVB receiver. probably a couple of other simple modules! Seller's rep' apparently did not understand the application I wanted to use it for, which is carrier strength measurement during solar eclipse, not the usual decoding...
Thank you very much!Read full review

Does what it says on the tin and does it well
Eager to play with my new toy, I quickly breadboarded a test circuit, driving an LED using a CMOS-input logic gate. Besides connecting power, ground and timecode out, I just pulled PON low and let AGC float. Nothing happened...until I TURNED OFF MY FLORESCENT LIGHTS. Once I did that, it synced up in a few seconds and my LED started flashing as expected -- Big Fun Now. The receiver seems quite sensitive; I do live in the primary coverage area of WWVB but it's still a thousand miles away, so I was impressed with how fast it synced up.
Included was a datasheet and the URL of the universal solder website, which has further documentation, including for the receiver module itself. Note that the timecode output can only source/sink around 5 to 15 microamps so you'll want to use something high impedance like a CMOS-input logic element if you want to drive an LED; I used a salvaged 74AC00. Or, just do what everyone else does and feed it into a PIC or ATMEL uP -- that's what I'm planning to do.

One of the few wwvb devices for arduino, works fantastic
Very nice device that allows you to connect an arduino up to the WWVB timesource. There are many libraries you can use with this including some that will re-transmit the signal for local "atomic" clocks that cannot pick up a signal (perhaps deep inside a building).Read full review

60 Hz radio receiver module
I have built MANY one-of-a-kind radio-controlled clocks that are microprocessor controlled. Formerly, I used the CMMR-6P modules, but these are no longer available. When I first tried out these units, I quickly found out that due to their high sensitivity (a good thing!), if you have any electrical noise in your circuit, take advantage of the AGC "hold" pin during switching. After that, these units out-perform the CMMR-6P units hands down. I'm happy with the results, and really glad that there is a good (better) substitute for the CMMR-69 units.

Great deal, great product
Highly recommended. These receivers are hard to find. This one is just like the ones you could get years and years ago. They're more sensitive (so you can pick up the WWV clock signal indoors easier) and work just like the old ones. Well done, guys! I loved the packaging and the accompanying "cheat sheet" business card.
Hobbyists, note this board does not come with the I/O pins soldered in. This is a good thing. Either you can put some in for breadboarding or you can solder hookup wires round the signal elsewhere on your project. Very adaptable.Read full review

Poor Package Choice For Shipping
The Seller used poor packaging for shipping the ferrite rods as one arrived broken; the other was fine.

Great module !
A highly specialist item that has been very hard to source for several years. Hats off to Universal Solder. The unit works great. Decoding is tricky, but that's down to your own code. There are plenty of Mbed and Arduino examples out there to decode WWVB60 data
Highly recommendedRead full review

Works Great..!!
Using one of these receivers with a PICAXE 08M2 and it works great.
The project is on the PICAXE forum under 'communications'.

Excellent WWVB radio receiver
Good quality and value, easy hook-up, exactly what's needed for DIY clock experimenters.
