Capital has a problem, which is that the audience has a different expectation of it in each area.
In the likes of central Scotland it's always been seen as the alternative to the heritage station and Real Radio, so it fits in perfectly to the market. However in areas such as the South Coast and, of course, London, it is the heritage station and is expected to do a bit more than just bang out the hits non-stop. Hence the mish-mashy presentation, mixing ultra-cool voiceovers, big competitions and big celebrities with 80s sounding sung Capital FM jingles and "Capital Reports". Lovely for the radio geeks, if a bit baffling.
But the people you have to blame for this situation are the advertiers. They didn't 'get' Galaxy, forcing a rethink. Advertisers, on the other hand, do 'get' Capital, so the idea of providing that to advertise on on a national scale must have been irresistable.
The problem now is matching up the different expectations of what the station should be doing, and I can understand why they might not have got that spot on first time.
Besides, most listeners probably don't actually notice the difference. They just want a station that bangs out the hits they love when they tune in. So the issue isn't as big as it seems.
