I always knew there was a gap in transmitter coverage from Sutton Coldfield in the Allesley area, I didn't realise there was a similar gap in Keresley, stretching as far as Stoke and Binley

I doubt whether coverage of COM7 (BBC4HD, BBCNewsHD, etc) is as good as shown on the map either, given that it's broadcast at less than half the power of the other multiplexes? It's not receivable at all where I live in Spon End.
