What, do you mean apart from the ones like Caroline that were never on FM?I can't believe you wrote that. The problem is that most stations are no longer on MW/LW. That includes the UKs most popular stations BBC radio 1 and 2.
How about some of the others on MW or Long Wave?...

That's quite a big list, isn't it? Just short of 150; and I haven't even counted the FM stations. Switching back to AM or FM wouldn't be much of a problem at all then. Just remind me again how many stations are on super-duper DAB+... What was it.... almost 20, if you count the religious radio stations?
Isn't this where we started?
The OP wanted to buy an A/B amp with DAB and I recommend he make sure it was actually DAB+.
Not really.
Where we started was you stating in quite a point blank sort of way that anything other than a DAB+ for a DAB radio would be a waste of time. I've countered by showing that there aren't actually that many DAB+ radio stations to choose from. You quite helpfully banged a couple of nails in to your own coffin with Ofcom comment.
