Interesting discussion re getting the 1PPS into a PC to synchronise a
timing program.
I use WSPR for ham radio and was wondering how to do this.
Can you tell me which (Windows) time synch programs can use the 1PPS on
DCD of the RS232 interface please?
Next step would be to build a variable

Since I had a couple of spare RS-232 driver gates, I built a simple PPS
extender/level shifter in my Thunderbolt Monitor kit. It is not as general
purpose (not configurable) as the Fat PPS kit from TAPR, but it works well for
the Thunderbolt. You could easily build the circuit on a piece of

Where those using the cat-5 wire as a twisted pair? If sothat's cheating
Yes. I was thinking that 4 pairs would be Rx, Tx, PPS, and power. If I need
Ethernet, I'll pull another Cat-5.

The RIPE ntp system does a little bit of this.

Pulse quality of single-ended RS232 over unbalanced twisted pair is going
to be pretty bad beyond a few feet. If you want to transport the 1pps over
twisted pair there are a couple of options:
Hi Brian,
I suspect this is true at one level, but what would be helpful to to *quantify*
it. What

Hi Jayson,
You may already be aware of it, but there's a set of historical recordings
of WWV and WWVH, covering 1955 to 2005:

As for the simulation, I'm sure it would be easy to do the tones and
clicks, but the voice announcements would need a considerable amount
