[UK-CONTEST] OT - RFI problem

[Gordon Brown]

Graham,
             I had the same RFI problem with my burglar alarm when transmitting on 20M.  The engineer who came to sort it out had no idea about what I was telling him but when he got  back to his office they were aware and came up with some ferrite beads which solved the problem. 
        I would be interested in any replies you get because I am sending Morse messages via next doors security light but they haven't twigged yet - after five years and many new bulbs.
73 Gordon G3MZV.

Folks

Forgive the off topic nature - but I reckon that someone on this reflector
will be able to help.

I need to explain RFI problems that I am experiencing on a site nearby me to
a non-radio type person. The problem is solvable I am sure (it's RF
breakthrough into an intruder alarm.) However, as I say, this is not at my
QTH - it's elsewhere, and I don't really know the people involved yet as
this appears to be an intermittent type of problem. So, what I am trying to
do is have an analogy ready, to explain that whilst the problem is only
present when I am around, it's not actually my fault, and that the company
that fitted the alarm should be called in to investigate. Has anyone found
an analogy or example that explains RFI problem and whose 'fault' it is?

Any help much appreciated
