I quite like DAB & FM
I have one of these Pure portables http://www.pure.com/products/product.asp?Product=vl-60799 when out-and-about. It's rechargeable and I certainly get a day's use out of it. Use it in the car via the phone socket and works along the M4 corridor from Bridgend to Newport but can't vouch for the Intercity to Paddington!
I rarely listen to AM stations and the bedroom radio is a Pure DAB and I have a small DAB in the kitchen. Nation Radio and Nation 80's are not on the FreeSat and a lot of the 80's / 90's stations are only available on DAB.
the two questions to ask are (a) is the BBC going to save much money by switching off some or all of their AM transmission but (b) is there anything sensible that can be done with the FM spectrum?
