Hi Paul, 1) Why not consider using GPS? Much more accurate, available globally, and you can get hardware fairly cheaply on EBay from the likes of Datum, TrueTime and others. You can of course consider building your own, using the excellent resources of this group.
2) If the clock was bought in Europe (I'm assuming mainland Europe) then probably used the DCF-77 signal from Germany. DCF-77 transmits on 77.5 KHz. The UK one - MSF transmits on 60 KHz. The code formats are however different. Meinberg in Germany www.meinberg.de/english produce a DCF-77 simulator which is available as a plug in to their GPS products. See http://www.meinberg.de/english/products/sim77p.htm for more information. They don't have an online manual for this product, but more information on DCF-77 is on the web site at http://www.meinberg.de/english/info/dcf77.htm Good luck.

What standard time transmissions might I be able to pick up reliably here in South Africa? We used to have one on 2500 kHz, but it seems to have gone, SA Bureau of Standards doesn't seem to know what I m talking about when I asked them. WWV comes in some times, and optimum frequency varies, so that's not what I'm looking for. I can get time pips from the FM services, but that will have been through an undefined analog-digital-analog satellite feed, so the delay is whatever it might be that day! 2. I have been given a digital wall clock which was bought in Europe. It is designed to work from European time signals, but the book (instruction leaflet!) doesn't say which - MSF? The German one? who knows! If could I get details of the frequencies and signals that these transmitters put out, I could make a local TX to drive it. At the moment it loses 1 second a day.
