Briantist: I certainly wasn't suggesting you work out the terrain for the calculations as well, just for us readers to consider if there's indiscrepancies from what we find on the ground.
Interesting note on the restrictions. The industry seems to herald the robustness of having multiple transmitters covering one point.
Re: Redruth, I was surprised how quickly the signal disappeared when terrain shouldn't have been an issue to the south. Thankfully the new-ish Helston tx more than substitutes, and as you said proves the signal extends well over the horizon/line of sight to reach the Lizard point.

Briantist: Cheers for the Redruth map. Certainly confirms by guess about the southern restriction, but so much easier when is visual than reading the tables and figures. Guess Helston was always going to be needed as part of the long term strategy.

Hi Brian,
I'm a big fan of your website - thanks for taking the time to fill it so comprehensively.
I'm particularly interested in DAB coverage, but have noticed that some transmitters added or upgraded over the last 1-2 years haven't been shown on your multiplex & mast pages. I appreciate other priorities on your time might have distracted you.
I've recently started to create my own google-based maps, but as I'm generally referring your site for accurate coverage extents I wondered if it could offer you my time to assist you updating these pages, reducing duplication and inaccuracies.
Please contact me if you're interested, and think I can be of assistance. Website writing skills might be limited, but I can learn, and I'm pretty knowledgeable of the latest DAB developments, referring to a number of reliable sources.

A great start, and thanks in advance.
It'll clearly demonstrate often the fininacial contrainsts and power restrictions used by commercial operators compared with the BBC.
Obviously a bit of local terrain knowledge will still be necessary, but the indication of the target area should help - especially when trying to seperate coverage areas of a SFN.
Hopefully it'll confirm my assumptions about the Redruth southerly retricted radiation. Much easier to read than scrolling through the Ofcom spreadsheet!
