Well, there is a very good reason to use analogue: it's already in place and working, and there are hundreds of millions (maybe billions) of analogue radios. T

Well, there is a very good reason to use analogue: it's already in place and working, and there are hundreds of millions (maybe billions) of analogue radios. The problem is that attempts to introduce digital systems have generally not been successful. If radio didn't exist, you'd obviously start digital services. But it does exist, and it's deeply entrenched.
