Radio controlled clock question

Oct 17, 2003 60 Replies

Rugby has never transmitted R4. It has always been for shipping and MoD work. Each of the big masts is mounted on a large ball bearing so that they can move in the wind. Some of them have a sort of lift arrangement up the middle. Its quite interesting to watch them in a thunderstorm, apparently they also produce roast beef and lamb in the surrounding fields. As a child, I lived about a mile from them.

As Dave said, I was mixing up Rugby and Daventry.

R4 on 198kHz is from Droitwich. I believe that Daventry is medium wave......

To email, substitute .nospam with .gl

Lidl in Holland have recently been selling cheap clocks like this. They can be switched between receiving the Rugby signal and one that transmits European time from a transmitter located somewhere in Europe. Perhaps yours has this feature, and is set for continental time..

Radio 4 from Daventry has a carrier wave on 198 Khz which is referenced to the national physical lab who in turn reference to God in order to provide an ultra stable frequency reference fore test equipment and the like.

Rugby wireless station transmits MSF on 16 Khz for time clocks etc. It has been down for maintenance recently which has caused some clocks some problems. It has a website something like

or other...FWIW...

Well, North of Watford:=-))

And Burghhead and Westerglen, phase locked to Droitwich.

Nope just DAB now...

The management wish to apologize for the piss poor quality control on this posting due to the imbibing of a good bottle of Shiraz:-))''''

Some interesting history for the anoraks here:-))

HELP, I've now encountered another problem! I decided to swap my RC clock for a slightly better model which also displays the temperature. However, the clock is now showing the time at 1 minute faster than it should be! No matter how many times the clock updates itself via the msf signal, the LCD display is always showing 1 minute fast! I first noticed this when I compared the RC clock to the time shown on BBC teletext.

The hour display and the seconds are spot on but the minute reading is fast by 1 minute! To double check I even rang the speaking clock and, sure enough, my RC clock was out by exactly 1 minute. I tried manually setting the clock to the correct time but as soon as it goes through the update cycle it reverts back to being 1 minute fast! Anyone know what could cause this, although I suspect my RC clock must be faulty.

I have no idea what might cause that, but just to eliminate the remote/silly possibility that the Rugby signal is out, I checked my RC clock against the computer (which I set over the internet from a different source) -- they're exactly aligned, so that's not it......

Cheers for that, at least it confirms the clock must be faulty. I can only assume that it must be down to some kind of faulty calibration settings at the factory? It certainly is a weird one!

On the uk.tech.broadcast group, a few people have reported errors in the MSF transmitted time during its maintenance. Even a transmitted time 3 hours out!

Is it possible that the clock face is slightly mis-aligned?

Or the minute hand. They are normall only a push on fit to the drive shaft, no splines or other locating device.

It sounded like a digital display to me, not an analogue.

He mentioned a "display" with minutes and seconds, though: doesn't that imply a digital display?

(Can you misalign a digital display?)

Ah - I missed that. I was thinking second hand, minute hand, hour hand.

I've never tried.
