Good point on the weather… interference and weather are the front runners. But you’re right – I hate not identifying the problem. I share your enthusiasm for debugging – if I discover anything helpful, I’ll post it here.

Meanwhile, it’s been a while since I’ve looked at the digital broadcast websites, but they don’t seem to be as well maintained as I recall. The broadcast power from Hannington is apparently incorrect for COM7 and the OTA update info at http://www.dtg.org.uk is well out of date… maybe updates aren’t as regular as they used to be?
