[QUOTE="Vipersan, post: 804240, member: 325666"] Ok ...fixed it ...but not by any means I'm happy with .. If I remove the T plate ...and fit either the DOS plate ..or indeed ..a small slice of the green commercial depolarising plate ..the signal is still around 6.5 db ..and the F15 remains locked ..the pictures and sound both remain constant. My conclusion is fwiw ..Wireless interference.. With the T plate fitted ..depolarisation takes place effectively outside the lnb throat ...and although dxing gain suffers as a result .. Christinas directional ONLY properties come into play with less external influences .. I believe the Wireless interference is So strong ..that it doesn't need a dish to collect it ..and thus is being picked up laterally by the T plate and funnelled inside the lnb waveguide. Its as good a theory as any ..and if you think about it ...makes perfect sense.. So no DXing at or around this specific Cband frequency using a T plate.. More reasons to climb up and down the blaady ladders ..but at least I'm now _aware_ of the problem. rgds VS Solution ..._dumb down at the head end_ Grrrrrrrrrr If nothing else it shows what an electronically 'noisey' world we now live in...
