It is a shame that no mention is made in this article of DRM, which the BBC helped to develop. It is a technology providing long distance "near FM quality" radio over HF ("short waves"). The technology, now approved by CEPT and the ITU also includes MF and LF frequency bands as well as FM.
Recent cuts in BBC funding have meant that their participation in this pioneering service, which could easily breathe new life into short-wave listening have been reduced.
The BBC currently transmits an hour daily (5 hours daily a year ago) from the UK towards continental Europe from Wooferton in the UK, and another 5 hours daily to southeast Asia, from transmitters in Thailand.
During the winter months, reception in Europe is generally excellent, and Babcock, the BBC's transmitting contractors, also relay programmes of NHK (Japan) and KBS World (Korea) from Wooferton into continental Europe in English and Russian.
The BBC is dwarfed in terms of broadcast hours by the "Voice of Russia" (with 7 hours daily to Europe in English, and 20 more hours in other languages - French, German and Russian), "All India Radio" (with 4 hours/day in English to Europe and about another 10 hours in other languages), and even the "Voice of Nigeria" manages 90 minutes/day.
