I have had a quick look on Ofcom's website to find out how many complaints "Nightmare Neighbour" received, as of today the programme received 39 complaints to Ofcom, however as the programme featured other segments alongside that featuring M0PAM those could have easily attracted complaints, however I have a gut feeling that the majority of those complaints were relating to the part about M0PAM and his battles with his awful neighbours regarding a harmless HF beam antenna.
As Ofcom have to assess all 39 complaints against the broadcasting code it may come to nought, also 39 complaints is a bit worrying, I was expecting a higher count as I know many many Amateur operators are outraged, and the RSGB at time of writing still have not heard from Channel 5.
I'll keep you posted on this as events unfold.

EDIT: I have subsequently discovered a further 12 complaints were received about the programme, this warrants Ofcom to investigate, alarm bells should ring here.
