Got into the International Herald Tribune today with a comment on the ending of BBC's English shortwave broadcasts to Europe. It has been interesting to see the short-wave die-hards trying to justify against the decision with facts plucked out of the air. They assume that shortwave transmitters are 100% efficient and that a 500 kW transmitter just takes 500 kW's from the grid. Sorry. Nearer a Megawatt. The older transmitters are more like 30% efficient. Yes, it is true, there are countries where SW is still the only way of getting a signal into a country. But that is not Western Europe.
And I am amazed at how die-hard radio listeners ignore the shows available on BBC World TV. Click is much better than many of the technology shows on BBC World Service radio. And it has almost as many people working on it. Face the facts guys, radio has become too wrapped up in its own routine and has not woken up to the fact that great content must be findable/searchable. The worst human interface ever is the old SW radio dial with a 1000 stations crammed into a few mm's marked as the 49 metre band. DRM's mistake was not being ready to pick up where SW analogue radio left off, i.e. not only with transmissions but a range of interesting programmes and cheap sets in the shops. It is a different story for parts of Africa, though even there the growth of FM is eating into traditional SW audiences. That's because local radio does local languages, adding information gleaned from international networks or grabbed from the web.
