Interference on in-house TV "senders"

    I am not having much success with 2.4GHz unlicensed band TV/video wireless transmitters. They are supposed to have a 100 metre open space range but mine are located probably 5 metres apart with 2 concrete wall with doors in between them. Reception is poor.
    Main problem is what appears to be some sort of interference. It comes up a bar rolling down the screen and a pule rate of about 5 times a second - it's like the interference you used to get WAAAY back from a badly suppressed car ticking over outside the house (and no there isn't!).

    I suspected one of the 2.4GHz devices in the house as a cause - DECT phone, WiFi router/modem, wireless door-bell - but turning each off in turn has not helped.

    Any ideas?

    My house used to use a UHF cable system but with Freesat and other boxes no having SCART but no UHF outputs that is no use.

    Rolling bars sounds like wi-fi interference alright.

    Do your neighbours have wifi networking?

    Do you have any games console running in the house? PS3 acts like a mini EMP blast to my wireless TV senders!

    There's a Wii beside the transmitter - but I did try turning it off - no change (didn't look at the handcontrol thing though...)

    A neighbour has a very strong WiFi signal - occasionally it's stronger than my own and I accidentally log on to it and get a 7MBits instead of my own 1Mbit oh dear :D ..... but I don't think that's it either.

    Another neighbour DOES have one oddball thing - weather station mounted on our fence - my guess is that it is using 2.4GHz to get the siga=nal into his house PC as I can see no wires so I might try shielding it with kitchen foil or just remove the batteries and see what happens.

    Trouble with tracking down this kind of problem is you get a bit suspicious of everything and everyone. Maybe some day when I am on my own I will flip every circuitbreaker in the 'fuse'box and put them backon one at a time to corner the little bastard.
