It does feel to me as if Bauer are putting a heck of a lot of eggs in one basket for a brand which is anything but tried and tested.
The Capital, Heart and Smooth networks all managed to prove their worth at a regional level, and be fine-tuned into really polished products, before being rolled out nationally, whereas GHR only has a handful of mostly dismal Rajar books in a few local markets so far, and is still undergoing a lot of tinkering. It strikes me as one very big shot in the dark for Bauer.
They must be absolutely convinced there’s a massive demand for this service. But if it bombs when Rajar returns, it could be a huge embarrassment for them. I think it’s a huge risk.
This is roughly where I am with this, too. I feel like it's too specialist a service to have replaced so many very generalist local stations. The UKRD family in particular seemed to do well in RAJAR from being a "something for everyone" local service, and the replacement is quite a specialist oldies station full of dad rock and geeky DJ links about chart positions ("that got to number three in 1978"). Its heritage is as an oldies service in northern England, it was the AM side of FM stations like Metro, Key and Viking, and that influence still feels very present in the current output.
There is always social media whinging when a station changes nowadays, but when the switch happened with these stations, there were a lot of comments from listeners complaining about the ancient music on stations which used to play a mostly 80s-90s-00s-today mix. I think it's disappointing to lose the localness, but even if they'd kept local programming and changed the format to this, they've still narrowed down wide-ranging stations far too much, and you're right that the tinkering should probably stop before the station is launched on London FM. It may be that Bauer have internal metrics showing that GHR is wildly popular and taking the nation by storm - we haven't had a RAJAR for a year - but I just can't see it. It feels like the kind of station that is going to be very popular with a small number of enthusiastic listeners, but Sarah taking the kids to football practice who used to listen to Minster will probably just spin the dial to Heart to get away from the endless Queen and Fleetwood Mac.
