长波广播时代即将在德罗伊特威奇发射台关闭后终结

英国广播公司(BBC)定于本周六结束长波(LW)广播服务,这也标志着伍斯特郡威奇博尔德(Wychbold)高达700英尺的历史性发射塔即将结束其时代使命。这些发射塔自1934年投入使用以来,一直是英国广播事业的关键,在第二次世界大战期间更是发挥了至关重要的通讯作用,包括协调诺曼底登陆行动以及干扰德国空军的雷达。 随着听众人数的减少和高昂的维护成本,BBC正将重心转向调频(FM)和数字平台,这些标志性地标的未来目前仍不明朗。尽管“英国历史遗迹”(Historic England)此前因原建筑物损毁而拒绝给予该遗址登录保护地位,但“二十世纪协会”(Twentieth Century Society)目前正在发起运动,呼吁保护这些具有工程和历史意义的发射塔。当地历史学家和倡导者也在推动将该遗址保存为国家广播历史中心,以确保这个曾经覆盖全国的电台传奇不会被遗忘。本周六,德罗伊特威奇温泉遗产中心(Droitwich Spa Heritage Centre)将举行纪念活动,以庆祝该电台92年的光辉历史。

随着德罗伊特威奇(Droitwich)发射台计划关闭,BBC长波广播时代已接近尾声。该电台最初在 200 kHz 频率运行,1988 年调整至 198 kHz,长期以来一直是 BBC 第 4 广播台的核心,播出的内容包括每日农业新闻等标志性节目。 此消息在 Hacker News 用户中引发了怀旧情绪与担忧,人们对这种历史性广播基础设施的消亡表示惋惜。评论者指出,这反映了全球范围内淘汰传统广播服务的趋势,并列举了加拿大时间信号(CHU)和气象广播类似关停的案例。尽管有人认为这些系统仍有其用处,但在数字时代,其过时已导致长波传输面临普遍衰落。

Long Wave radio era set to end with switch-off

Local history expert Alastair Moseley said he backed a campaign to get the Wychbold masts listed status

A campaign has begun to get two large transmitter masts listed, after the BBC's Long Wave (LW) service is turned off.

The 700ft (213m) high Wychbold Masts in the Worcestershire countryside can be seen for miles and are often used as a landmark for drivers on the M5 near Droitwich.

They have been in use since 1934 for sending the signal across the country, as well as for transmitting important messages during the World War Two.

Local history experts and the Twentieth Century Society have called for them to become listed, due to their "historical importance".

Droitwich was picked as a central location for the station and masts so Long Wave could reach everywhere in the UK.

The construction was a big operation for the time and local expert Alastair Moseley, from the Bromsgrove Society, said a huge team of workers had to come and put them up

"It cost £200,000 to build then, that's about £20m now, which actually is quite a good value I think," he said.

"But the towers themselves were built by just 10 riggers and there was one particular guy, Derek Pigeon, who actually had just come over from building Sydney's Harbour Bridge."

On the 6 September 1934 everything was ready to go, and the first thing the country heard on LW was a musical piece by composer Eric Coates, famed for the Dam Busters theme, called The Merry Makers.

A few years later, when World War Two started, the masts had a new job to do as Moseley explained.

"They were used to block transmissions and radar facilities from the Luftwaffe, so that they were almost blind when they were coming in to fly," he said.

"They also transmitted messages to the French Resistance, they had a part in that so it was very covert.

"And D-Day, they were part of the co-ordination of communications that were needed to make that such a successful landmark event in history".

After the war, the transmitting station returned to its usual broadcasts.

In 1957 officials held an open day but public interest was so high that 13,000 people turned up to take a look.

That led to other transmitting stations across the country having their own open days, particularly those with new TV masts.

Over the years, the equipment was changed from analogue to digital and several other smaller masts were built for the Medium Wave signal.

The Wychbold Masts will no longer transmit LW with the switch-off expected at 00:01 BST on Saturday.

A spokesperson for the BBC said the move came as the equipment was reaching the end of its life.

"As Long Wave is an older broadcasting technology, recent years have seen a decline in listener numbers, with the majority now opting for FM and DAB digital platforms," they said.

"Given these factors, investing in upgrading the LW equipment is not considered a cost-effective solution for licence fee-funded services".

Equipment including a radio control desk with dials and knobs are displayed in front of a wall which includes photos of what the transmission station looked like and a poster for an Annual Dance being held in Droitwich in 1957.

The transmitting station's history is captured in a special exhibition in the town's heritage centre, called Droitwich Calling.

Old equipment and photos were donated by former BBC engineer John Phillips, who worked there his entire career.

He wanted to make sure the masts' legacy continued and worked with the centre until he passed away.

Manager Rebecca Butler said the exhibition was important to keep awareness of the masts' legacy alive.

"We're telling the stories of Droitwich Transmitting Station for future prosperity, we're holding onto these artefacts for the future," she said.

"There may be a time where those masts are no longer here, but for 92 years they have stood strong and I feel like it's something that we need to be proud of".

An event to remember and celebrate the history of the transmitting station is being held at the centre on Saturday from 12:00-16:00.

Historic England did consult on potentially listing the site in 2025 - but ultimately decided they did not meet the criteria, mainly because so much of the original buildings were demolished.

Granting a building listed status gives it special protection.

The Twentieth Century Society, who campaign to save "outstanding buildings" from the century, want the masts themselves to be specifically considered.

A spokesperson said they have broadcast such "national staples" as the World Service, the Shipping Forecast and Test Match Special, as well as their role in the war.

They should be listed "on account of their historic importance and architectural, engineering and technological interest"," they added.

But for Moseley, there is another idea for the site - a museum.

"If there was just some way of having a museum of some description on the site and maybe keeping parts of the towers, I'd love to see this as a national centre for broadcasting history," he said.

"That would be marvellous for the whole region"

The current site's owners, Arqiva, were approached for a response about the future of the Droitwich Transmitting Station.
