FYI
VM called - put a meter on my V+ - signal was very, very low
guy said that if you have low signal, the BBC channels are always the first to drop out
he tweaked me up a notch on the box outside (my BBC channels are back to superb)
took him less than 10 minute including going outside
he even left he mobile number incase it needs a bit more tweaking
so crank it all the way up i here you cry - he said that could interfere with my b/band
very pleased i be
