Hello,
Does anyone have any schematics or recommendations for such for
building a WWV receiver? I can't afford to buy one due to
disability-related medical expenses, but I could afford to build one
with some help. The help I can get. The schematic I have not. Can you
please help? Thank you very much.


There are several computer programs to sync the clock in any commputer
to a source with tied to NIST via the internet. If you turn on all the
features it automatically adjusts for the round-trip delays, and the
drift in the crystal on your PC and will be accurate to 10's of
milliseconds.

This is called NTP (Network Time Protocol)

I can think of a couple of ways to set this up if you have
a dial-up internet connection.

See http://www.eecis.udel.edu/~mills/ntp/
and http://www.ntp.org/


Here's a very good and easy to use application... It's called D4 (Dimension
4) time.

http://www.ise.ufl.edu/kisko/files/f...20Time%20Sync/

Works with Win9x/ME but not with XP (XP has it's own time sync application).

Are these time sync' applications/websites free of spyware?


I can't speak for each and every clienet NTP package, there are
probably a hundred, but NTP was developed at a university, (UDel) and
most of the software is free and opensource, with no related
commercial version for sale. About as uncommercial as it gets. For
the truly paraniod, you can download the source, read it for yourself,
and compile it. There are commercial products inat include ntp, but we
aren't talking about them.

NTP, proper is a public protocol specification, not a product or
service, and is part of the same specifications that constitute TCP,
IP, and the internet itself. The spec is RFC2030
(http://www.eecis.udel.edu/~mills/dat...fc/rfc2030.txt). If someone
added spyware it an NTP software package it would be outside the RFC2030
specification.

There are about 120 primary (stratum 1) servers, run by many
goverments, and NIST, and The US Naval Observatory. (They may spy,
but if they do you'll never catch them at it ;-) ) All the second
level servers (stratum 2) are tied to the the stratum 1 servers.
There are 174 stratum 2 servers in this list but many more in reality,
run by universities, businesses, and goverments all over the world.
You could set one up youself if you bought the equipment necessary
(big bucks). See http://www.eecis.udel.edu/~mills/ntp/clock2a.html

You and I should never talk to the stratum 1 servers, (you could, just
to prove it worked). The level 2 servers exist to share the load. You
can pick any one you want, usually close to you.

This a public service, not spyware.
