A friend was given a clock that syncronizes itself to the 60kHz time
signal broadcasts. I know there are stations in the US (WWV?) and one in
Germany. The clock cannot receive either here in Israel.


The time signal here in the UK uses 60 kHz (MSF Rugby) which I have picked
up in N. Italy on my clock. My wrist watch is updated by DCF 77 in Germany
on 77 kHz.

From this list it seems MSF is the only one in range.

• Rugby, UK (MSF) 60kHz, 15kW
• Mainflingen, Germany, (DCF77) 77.5kHz, 50kW
• Colorado, USA, (WWVB) 60kHz, 50kW
• Fukushima, Japan, (JJY) 40/60kHz, 10kW
• Kyushu, Japan, (JYY) 60kHz, 10kW

Can you pick up BBC Radio 4 on 198 kHz at night (say 0300 UTC)? If so, you
*might* be able to receive Rugby.

What's the problem? Tune in any one of the available frequency and time
standards around the world and set your clock.

I've never used a 'synchronous clock', seems like a waste of money.

If you've a need for absolutely precise time you'd be better off using some
other, better method than one of those clocks.
