Evening Graeme,

Take no notice of that other crude bugger!!
The problem is that I'm up a rural no-through road that becomes a Bridle-Path onto the Exmoor National Park a couple of hundred yards past my place and all the lines are up on poles running through trees, somewhere nearby there's a bad joints and when the trees/lines thrash around, the phone pops and crackles, it's a wonder that it can pass data at all.
