The Jazz' was my reason for buying a DAB radio, so I'm really dissapointed that it's closed down. It was an oasis of difference from the usual daytime dross output on Radio2 and other commercial sites. Clearly keeping a station on-air requires revenue and The Jazz ran very few ads. Still I am hopeful that more genre based music radio will be available in time. DAB is wasted on the likes of mainstream BBC voice only products since FM serves them so well.

DAB reception on the move is so poor that in-car or mobile DAB is no match for FM, despite FM's patchy mobile reception.

The majority of people are unlikey to buy a fifty quid plus DAB unit unless, like me, there is something more to be gained; were The Jazz not to have existed I would certainly not have purchased a DAB radio just to listen to the same content as I can get on FM.

I am strongly opposed to any form of coersion being used to force people to switch to DAB from FM.

I agree with the 30 January media reporting of Enders Analysts concerns over volume of DAB stations, which I guess is another reason why senior executives are leaving the industry. DAB multiplexes are swamped with stations few listen to, therby reducing audio quality by deploying low bit rates.

My excitement with DAB is its improved reception of existing well established local and national AM stations like 5 live, complementing existing FM stations which need not be duplicated on DAB. The addition of stations like the Jazz and Planet Rock are welcome and popular, but we really don't need many more, nor I suspect can the market sustain them.

I would like to see the termination of all AM transmissions, retaining FM with DAB. An ideal compromise if the going gets tough?

Pure DAB radios can be upgraded to DAB+ with a software upgrade. The government should announce a switch off date ASAP otherwise the industry will stagnate.
