I take your point. But interesting MCAs (which as I’m sure you’re aware are different to the station defined TSAs) don’t cover areas like here in North East Worcestershire when these stations have always targeted the area and they are well listened to. I don’t know how many of those other areas are like that!
Yes there's always differences between where stations should go and do go and where they say they go!
In my experience Redditch/Bromsgrove way (which I assume is where you are) do get the West Midlands stations fine but once you head past there west or south into the rest of Worcestershire they soon disappear.
Funnily enough I listened to a bit of Signal 107 this morning and and was odd to hear Hereford (i think) news with GHR jingles, I hadn't realised they split their news. I wouldn't be surprised if the Wolverhampton/Shropshire bit of what is now Signal 107 becomes essentially an extension of 105.4. Thing is that even with the extra mostly rural areas it gets from Signal 107 it gives GHR the edge over Smooth and Heart
