The wrong type of weather for good TV and radio reception?


The sun is out, and with climbing temperatures comes the risk of TV and radio interference.

High pressure centred over the UK will provide ideal atmospheric conditions over the next seven days to lift TV and radio signals to reach areas beyond their normal coverage zone.

As a result, incoming interference may cause temporary disruption to Freeview, DAB and FM signals. Northern areas are initially most at risk, followed by most of Eastern and coastal southern England during the course of the week.

The BBC has today advised that the issues are "caused by a zone of high pressure, which causes problems to the links between transmitters and increases interfering signals in the area, which results in poor reception."

Viewer in marginal signal areas are most at risk from interference.

FREEVIEW
On Freeview, interference may manifest itself through pixelation and signal drop-outs. Viewers are advised not to retune, as this may cause channels to disappear completely from the channel list and the receiver may inadvertently receive other distant signals or wrong regional versions that will disappear when conditions change.

There are no frequency changes planned during the World Cup, and the only channel changes scheduled are relatively minor, including the Sewing Quarter moving to channel 73 during the course of the 26th June and the addition of BBC Red Button streams on Freeview HD, YouView and Freeview Play compatible devices.

Not all services might be affected in any given location, with the main five channels and offshoots generally being allocated the clearest, strongest signals in each area.

The BBC-funded Radio and Television Investigation Service offers more information about weather related reception problems here. It advises that the problems will go away automatically when the weather conditions change.

Viewers who are frequently affected by weather-related reception trouble may wish to consider cable, satellite or internet-based alternatives.

FM AND DAB
Atmospheric conditions may result in you receiving more distant stations, even continental radio stations when tuning your device. Local stations may experience temporary distortion, including drop-outs and bubbling sounds on DAB.

While it may be the wrong type of weather for regular TV and radio reception, radio enthusiasts will take the opportunity to see how many distant broadcasts they can receive in the coming days, with airwaves full of signals from across Europe.
