In just a few days time the BBC will shut down the Long Wave service for BBC Radio 4. Its closure will leave the Long Wave dial deserted for listeners not only in the UK but further afield too [Guardian / RadioToday].
Broadcast from Droitwich in Worcestershire, BBC Radio 4 long wave, transmits on the 198 kilohertz frequency and relies on ageing transmitter equipment that uses a pair of the valves which are no longer manufactured [Wikipedia].
The site was chosen as the mast could send transmissions to most of Britain and, at the time of its erection in 1934, was described as the World’s most modern Long Wave transmitter [YouTube].
Droitwich replaced the Daventry transmitter which itself had taken over from Chelmsford on the 27th July 1925. While the Chelmsford and Daventry Long Wave transmitters were closed due to obsolescence, there was no hue and cry. Droitwich could now cover most of the country with one mast and broadcasts could even be received on the continent and far out to sea.
Long Wave is considered obsolete with few people having sets able to receive broadcast on the band. Nonetheless the imminent closure has broad loud voices of protest from a minority of listeners.
It is estimated that around 90,000 homes in Britain still listen in to BBC Radio 4 on Long Wave, particularly in areas where short-range FM and DAB [Digital Audio Broadcasting] does not penetrate.
An announcement that has been playing for some time on BBC Long Wave transmissions for some time informs listeners that they can listen online, via the BBC Sounds app, and on FM and DAB.
However in many parts of rural Britain this is virtually impossible. In many parts of Wales there is almost no FM radio reception and almost no cellphone coverage [Richard Mudhar].
For those in rural Wales or Scotland it’s not a matter of life and death, though boredom may set in for some without their daily fix of the Archers. But for some fishermen they could well be lost at sea.
The BBC Shipping Forecast has been feature of British broadcasting since the days of the telegraph in the 1860s [Wikipedia].
Established by Vice-Admiral Robert FitzRoy, the first professional weather forecaster, captain of HMS Beagle and founder of the Met Office, the shipping forecast has become a British institution.
Many listeners will be familiar with Dogger and German Bight even if the information imparted in the twice daily broadcasts is somewhat irrelevant to them.
But for ships at sea the BBC Shipping Forecast remains a vital failsafe for maritime safety while also functioning as a cherished national cultural institution, having celebrated its centenary.
July 4th 2025 marked the centenary of its first BBC broadcast. And in that time it has prevented the loss of countless lives at sea.
But what will happen when Long Wave ceases to broadcast? While the broadcasts will be relayed on maritime frequencies as well as BBC Radio 4 FM and DAB, some are concerned that the gap may not be filled.
Long Wave reaches far out to sea, beyond Fastnet and along the edge of Iceland. Fishermen have even received the midnight news south of the Azores. Through the shash and crackle, many seafarers have leaned over a radio and scribbling down details of the shipping broadcast.
Of course it is not just the vital information imparted by the twice daily shipping broadcasts that those at sea strain their ears to listen to. Others would huddle around the wireless to catch the latest installment of The Archers or a comedy show [Yachting Monthly].
For those on terra firma, or not living in the isolation of the Scottish or Welsh hills, the shutting of Droitwich will have little impact. For radio enthusiasts it will be the end of an era. Old radio sets such as the iconic Bush TR82B, designed by David Ogle, will become all the more obsolete. Even Medium Wave is falling into decline with the BBC having switched off most of its local AM and Radio 4 Medium Wave frequencies. National stations like BBC Radio 5 Live [909 kHz and 693 kHz] and commercial networks like TalkSport are still broadcasting on MW, but the dial is gradually filling up with static.
While there have been campaigns calling on the BBC to rethink its planned shutdown of Doitrich, and with it LW transmissions, the BBC says that it is economically unviable [Keep Longwave].
The transmitter relies on two 1 metre long tubes or valves which are no longer made. The BBC is said to have bought up the last of the available tubes. [R-Type / BBC Engineering].
It is unclear whether these remain in reserve or whether the corporation is down to the last two. Either way a failing tube could damage other parts of the transmitter, and maintaining the facility as it is has become more difficult.
Using tube and valve technology, the transmitter is more resilient to EMP, though it is likely that there are parts that use modern electronics which would be vulnerable. But it is the penetration that LW offers that will be lost by the shutdown.
LW can be picked up even under the sea and some have speculated that submarines might even monitor BBC Radio 4 broadcasts in order to determine whether Britain is still there!
The wide coverage of LW has made it valuable during a national emergency. One LW transmitter can cover the entire country while FM or DAB requires a multitude of transmitters and relay stations.
So this begs the question as to why the BBC doesn’t simply upgrade the transmitter to use modern components rather than rely on old valves and tubes. The BBC has said that while possible it would cost many millions of pounds and, as such, an upgrade is not cost-effective.
It maybe that the site will be mothballed and that some of the equipment may be maintained for a ‘rainy day’ when the transmitter might be needed, perhaps for military purposes.
It is not the only switch off that Britain has experienced in recent years. The television terrestrial switchover started on 17th October 2007 and was completed by the 23rd October 2012 resulting in the end of all analogue TV broadcasts.
But even digital TV broadcasting may not be safe. Freeview, as it is commonly referred to, is at threat of being shutdown as household switch to Freely, an internet based service, as well as internet streaming services such as Netflix, Prime and other providers.
It has been predicted that by 2034 Freeview could drop to only 1 million UK homes from 9.7 million today. Its Internet based successor, Freely, is forecast to climb to 10.5 million in the same period. Sky is seeing more subscribers moving to Sky Glass, its Internet based service, rather than making use of a dish and satellite receiver.
And across Britain the telephone infrastructure is undergoing a major overhaul as the country switches from old copper analogue lines to digital VoIP (Voice over Internet Protocol) lines.
This too threatens to leave some people, especially in rural areas, at risk. Unlike traditional copper wired telephone line which are always live, digital Internet reliant lines are at risk if there are power outages.
Power outages don’t affect traditional telephone lines since back-up generators kick in should the national grid go down.
In a big town or city a modern digital line being unavailable may not pose a major problem since mobile networks would likely fill the gap and enable people to contact emergency services.
But those in rural areas such as the aforementioned Welsh hills could find themselves without any communications at all [Guardian].
There are advantages of digital switchovers. There are few that would argue that CDs sound better that scratchy records. Digital cameras have made photography more accessible and easier. The expensive days of using analogue film are long gone along with the annoying bits of dust on negatives when attempting to print an enlargement in the darkroom.
Perhaps LW is obsolete, given how few radio sets are out there. But the closing down of BBC Radio 4 on the 1500-metre wavelength will be a sad day for many.
