WWVB RECEIVER Infomation

Ok, I'm a newbie but hopefully the following info is helpful.
In researching WWVB receivers and inexpensive solutions for a stamp
project I came across the following. Again, I hope it is of some use.
OEM Module to receive and decode WWVB Time Signal
http://boulder.nist.gov/timefreq/general/receiverlist.htm
Little article about how to build circuit
http://www.buzzard.org.uk/jonathan/radioclock.html
Source for modules www.maplin,co.uk
MK68Y: EM2 MSF Rcvr Module:19.99UK
MK72P: MSF Antenna:4.99UK
MK73Q: MCM-RS232 Module:24.99UK
Info about an old HeathKit GC-1000 also describes the data format.

Also see Nuts & Volts Archive on www.parallax.com, Column #51
(expensive option) uses UltraLink module.

WWVB Receiver and a Nixie Tube display project (cute article)
http://www.amug.org/~jthomas/wwvb.html
Clock movement with receiver (alas, analog output)
www.klockit.com
Of course if you have Internet access on your microcontroller you can
use the free NNTP protocol and get the time from Boulder CO
http://boulder.nist.gov/timefreq/service/its.htm
Boulder also provides a simple string with the current time at:
http://132.163.4.102:13/
PIC based WWVB Decoder
http://www.geocities.com/hagtronics/wwvb.html
Here is an article on how to build your own WWVB receiver with IC's
http://lakeweb.com/rf/wwvb/
A GPS Receiver for about $100 will also do the trick
I have no idea how you would get any of these chips but they seem to
be the perfect solution!
