I have just received a letter from Ed Vaisey MP. The last sentece reads:
"It would not be in anyone's interest to force stations on to DAB or to "switch off" FM at a time when it would leave any local stations without an appropriate broadcast platform, The assurance we can give, therefore, is that FM will continue for as long as it is needed and viable."
Sounds good but does not of course stop the BBC acting unilaterally to cut their FM transmissions. However, I suspect that a big plank has gone from their stance now.
