Now here's a thing... why does the majority of content going out on FM get aired on AM at the same time as well?
Is there any reason why, for example, the 21:00 and interest (non music) slots aired most evenings are not aired during the day on AM?? Or some of the Podcasts during the day when the FM frequency is banging out mostly music. Not everyone has access to the internet, especially the older generation who are more likely to be interested in 'grown up' stuff.
Personally, I think there's pretty good 'interest' stuff on the Podcast section that could be repeated on air. Additionally, if MR are going to do justice to the Manx Gaelic offering then I'd certainly have no objection to it being aired on AM.
Unless there's a good technical reason why AM airing can't be aired with previously recorded programming alongside FM then I really do think we're being short changed. They're really not fulfilling their public service remit as it stands.
As Donald said earlier... the vernacular looks set to be the norm.
