Having looked at this site, and the other, there only appear to be 4 offending circuits, specifically, the Car anti-theft wireless alarm, the Radio Remote Control using DTMF, the Simple Car Battery Charger, and the TV Remote Blocker.
So, as has been already stated, the simplest solution is to remove those offending circuits. I don't think anyone will miss them too much.
PS navman, there's no need to take such a nasty attitude. We're quite happy to deal with REASONABLE people.
