I am lucky. I just happen to be in a location where I have clear views to the horizon - at least I do in one direction. As the lady says, location, location, location is the key and here it is really just luck..

Great screenies John, it just shows what can be done. I'll just have to demolish the neighbour's house whilst they are away on holiday...

I am now using Planeplotter and will leave it running for a while to capture tracks. As these build up they give an idea of the range the aerial is covering. And the best so far is an EasyJet I watched all the way down Mayfield which must be a good 230nm.. John fossil@xxxxxxx
