Think its more of an issue like (should have said I tuned the channel in previously with slightly different alignment and an Inverto LNB, so not phone interferance):
36E with The Media Office on 10955V [

So Alignment, LNB Skew & LNB type Used are all probably factors (Colin a m8 with Electric Engineering qualifications used an MTI one in my instalation, but I think he used a bog standard one, which is great for fixed dish instalation, you can peak the alignment, lnbs, skew's to get the best from all freqs, But motorized requires the best from your LNB [more chance of catching interference from adjacent satellites and other factors] Loooking at MTI Blue Line or Technomates TM-1 Gold)
