I read in another post about NetStumbler which I've downloaded and installed.
This showed my next door neighbour was also on Channel 11 so I've moved away to Channel 4... let's see how we get on with that.
The other thing I'd like to ask about is the Signal to Noise Ratio. Which is better, a high or a low value? For example NetStumbler tells me I have an SNR or 58 and my neighbours is 11... I'm guessing lower is better... the next column seems to show that my peak signal is 39 and his is 82.
I feel like I'm going down a rabbit hole!
