>The clocks with an LCD display usually have an indicator which shows
>signal strength if the clock successfully updated in the last hour.
>If you have reception problems, try moving the clock. The built-in
>ferrite rod is very directional.
>Were you receiving Radio 4 on LW or via a digital service. You could
>easily see a 3s delay on digital radio or TV.
