VirtualWire library uses timer1 so pins 9 and 10 are not available for analogWrite() as they require timer1 to be set up differently.
Use 3,5,6 or 11 instead.
I ended up back with VirtualWire, as the transmision was not as reliable with EasyTransfer, and I took Marks advice and cut some tacks to swap pins on the boards, so 18 hours later I have it running, though I have had to add some averaging to the light sensor to stop the dimming pulsating ( which I didnt have to do with the other version )
One day when I get some time I will look into this to understand it better.
Thanks guys
