Fair enough you have more info than I do.
My only experence of this is having an airprox while under an old RAS and the traffic was never seen on radar because that mosaque thing. Well that was one of the factors along with microlights not giving a very strong return linked with them not going very fast causing the software to not to paint them on the controllers screen.
But by your handle alone I bow to your knowledge and conced I was talking bollocks as it is obviously your area.
