At 75, U.K.’s last public shortwave site provides essential info to listeners globally via analog and digital broadcasts

WOOFFERTON, England — Nestled in the beautiful Shropshire countryside, just a few miles from England’s border with Wales, is the tiny village of Woofferton. That name is synonymous with shortwave radio for millions of listeners around the world as just a short distance from the village itself, lays the United Kingdom’s last remaining public service shortwave transmitting station.
Antenna switches in the field feed the HF curtain arrays.

Now owned and operated by Encompass Digital Media, Woofferton recently celebrated its 75th birthday. Built in 1943, the station has a fascinating history; originally designed to bolster the BBC’s General Overseas Service (now the World Service) during the latter years of World War II, it was later partly funded by the United States and was used extensively by the Voice of America to broadcast into Eastern Europe and the former Soviet Union during the cold war years. Today, Woofferton transmits programs for the BBC and a number of other international broadcasters, reaching audiences across Europe, North Africa and the Middle East.

There are 10 high-power HF transmitters at Woofferton. They range from Marconi senders of various vintages, including two BD272 250 kW units that date back to the 1960s, to the more recent 300 kW B6124 solid-state transmitters, and four of the most modern RIZ 250K01 wideband systems, which are also capable of operating in Digital Radio Mondiale (DRM) mode. In fact, the BBC’s daily DRM transmission for Europe is broadcast from here.

Outside in the antenna field, there are 35 shortwave curtain arrays (aerials) supported by 25 masts. Most of the antennas can be operated in full or half-curtain mode, depending on the coverage required, and can be electronically steered (slewed) to beam transmissions in a variety of directions. This is done by varying the phase of the signal and feed points to the antenna, rather than by physical movement.
