How voices from Daventry travelled the world
This years marks the centenary of the opening of the BBC transmitting station at Daventry in carried the BBC World Service to countries across the world from 1932 to 1992 and was also the site of the world's first national radio how did this small town in the Midlands become a famous name across the globe? Why was Daventry chosen as a transmitter site? When the BBC sprung into life in 1922, radio broadcasts could only be made over short company's chief engineer, Peter Eckersley, believed it was possible to create a long wave transmitter that would serve most of the BBC decided to find a site for a transmitting station that was situated north of a line between the Severn and the Wash, surrounded by as much land as locations were explored and Borough Hill in Daventry turned out to have the best coverage of BBC bought 58 acres (23 hectares) of the hill and started work on constructing the station. There was no road to the top, so it built a rack and pinion railway to haul building materials up the 128m (420ft) masts were erected with a lattice of copper wires and aluminium transmission equipment was housed in a spacious hall with cathedral windows in what became known as the 5XX building. What was the first radio service to be broadcast from Daventry? The station opened on 27 July 1925, with a poem called The Dane Tree written by the-then poet laureate, Alfred first broadcasts, for the BBC's National Programme, mainly originated in London and included plays, like The Glittering Gate, the story of two dead was also music, including popular songs and orchestral items. When was the BBC World Service first broadcast from Daventry? The BBC governors had been considering the idea of broadcasting beyond the shores of the United Kingdom for some corporation's engineers knew that short wave radio signals could travel long distances by reflecting off the ionosphere, part of the Earth's atmosphere, making international broadcasting in 1932, they expanded the site at Daventry and installed two short wave transmitters to send out the Empire Service, as the World Service was then called, to four zones across the a speech to mark the opening on 19 December 1932, the BBC's director-general John Reith warned that the early programmes "will neither be very interesting nor very good", but he also said the launch of the service was "a significant occasion in the history of the British Empire".He predicted that "broadcasting is a development with which the future must reckon and reckon seriously". How big did the international operation at Borough Hill become? As time went on, more services were launched to different countries, and complicated schedules of frequency changes were needed to keep the radio stations on air as atmospheric conditions changed during the engineer John Barry recalls services being broadcast in about 38 languages in the added that most of the languages were for eastern countries, as "in Asia, there are various vernaculars of Chinese, Indian, etcetera whereas, if you broadcast to the west, it was mainly Spanish". What impact did the transmitting station have on Daventry? People living in Daventry reported hearing programmes through metal items in their houses, such as taps and kettles, as well as chimneys and Viveash, another retired engineer, said other aspects of daily life were affected: "When TV started, [the radio signals] did cause a lot of interference with TV, so we went through a bit of a period being unpopular."When cars started to get in-built burglar alarms, you'd get the sound of the programme coming out of the car when you got into it."BBC sports teams were created and a BBC club was opened in Sheaf Street.A number of the men who came to work on Borough Hill ended up marrying local women. Why did the BBC station at Borough Hill close? There were two main reasons why the BBC vacated the Cold War, a period of tension between the USA and the Soviet Union , was over so the USA's international radio service, the Voice of America, moved out of the BBC's site at Woofferton in Service transmission could then be transferred from Daventry to modernising the Daventry facility would have involved constructing a large number of self-supporting towers on Borough Hill in place of masts held up by would have been expensive, and may not have enhanced the Daventry Bird, who worked on the hill for nearly 50 years, was given the honour of switching off the last transmitter on 29 March exhibition is currently open at Daventry's museum telling the story of the BBC's time in the town.

Ifi's Up Travel is an audiophile-grade, pocket Bluetooth transmitter
You'll find plenty of Bluetooth transmitters on Amazon that will let you connect your wireless headphones or earbuds to an airplane's seatback entertainment systems, but few do double-duty as a Bluetooth receiver, and I've yet to find one that offers the sheer number of codec choice as Ifi's new Up Travel. At $99, the Up Travel is among the pricier options for this kind of device, and probably not the right option if you just need simple connectivity. However, if you're passionate about wireless audio quality, it could be money well spent. Inside the tiny, flip-open enclosure, which works like an automotive key fob, Ifi has used separate chips for Bluetooth transmission and digital-to-analog conversion (DAC) functions, plus there's a dedicated clock circuit, which can often be the weakest link in a digital audio signal path. Recommended Videos You can use the dongle as a transmitter (taking an analog signal and sending it wirelessly to your headphones) or as a receiver (sending wireless audio to a hi-fi system or car audio system from your phone). In both cases, you can choose from a big list of high quality Bluetooth codecs: SBC AAC (receive only) aptX aptX HD aptX LL (low latency) (transmit only) aptX Adaptive LDAC LHDC/HWA (receive only) Switching codecs is easy. A dedicated button cycles through the list, with a color-coded LED confirming which one is active (yellow for AAC, light blue for LDAC, dark blue for aptX, etc.) The same button can also be used to alter the sample rate of the DAC: 44.1-48kHz or 88.2-96kHz. When using the Up Travel as a transmitter, you can still use voice applications like calling or Zoom, using the dongle's built-in microphone. It has Qualcomm's cVc technology — the same algorithms used on a wide variety of wireless headphones and earbuds to minimize background sounds when you talk. Like other options such as the AirFly Pro, you can connect two headphones or earbuds to the Up Travel for simultaneous listening. The Ifi Nexis app can be used to access customization options and update firmware. The only downside, relatively speaking, is battery life. Ifi rates it about 10 hours, which is less than you'll get from similar devices. You'll also need to buy a dual-prong adapter in case you end up on a plane with one of these older audio interfaces.
