When something works well, it just works. You do not need to analyse why it works. It just works. And nobody asks questions as to why or how. That is the case with FM radio. During half a century of development, more and more FM transmitters have been built across the UK (2,100 currently in operation) so as to reach the point now where almost the entire population receives an FM signal (maybe not always perfect, but some reception rather than none at all).
DAB radio was intended to replace FM radio. However, it must only be worth replacing FM with DAB if DAB is actually better than FM. Why replace a transmission system that has taken 50 years to perfect with something that is going to be worse? Unfortunately, nobody thought to conduct a cost/benefit analysis during the last two decades to determine what the cost would be of making DAB radio reception as good as FM radio, let alone better. As a result, DAB radio was foisted upon the public in 1999 without a roadmap to ensure that reception was even as good as FM radio for consumers.
Twelve years later, DAB reception remains worse than FM reception in many places, or is non-existent. Whereas poor FM reception gives the consumer a poor quality listening experience, poor DAB reception provides no listening experience whatsoever. With DAB, a poor signal is the same as no signal.
