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.

Is it a question of we are simply out of range of either of them,
or it needs a better antenna. A sheilded loop and preamp would not
be hard to make, but I don't want to waste my time and possible
damage to his clock if there is nothing to be gained.

Any ideas?

One that came to me is to take the time from a computer synced via NTP
and transmit a signal on 60kHz to the clock. A microwatt or two would
be more than enough, and any antenna at that wavelenth I could build
would be a point source so radiation could be easily limited to a few
feet.

TIA

Geoff.
