I thought that was a load of old fanny untill my telly started going a bit iffy.
Little Sussex stuck a magnet over it and the bloody thing started working properly again.

Nope, there are so many things that radiate RF waves these days. I remember a few years back that a data unit was not working, nothing we did helped. So we stripped the whole kit out, rewired and still not logging in.
Test kit in another car, no problem at all. We listened to the data channel and could hear a pulse noise.....??? Hmmm.
So started pulling fuses out of every bit of kit in the car. Evenutally the problem was traced to the taxi meter, it was radiating noise. So driver got a replacement meter and everything worked well.
Two of the worse case of interferance was
1. Voice radio channel lots of noise, cant hear drivers. Evenutally problem traced to a faulty CCTV camera outside the front window.
2. Data channel not working correctly. Again checked everything then noticed the noise in the back ground, not that noticiable at first but it caused a lot of signal hash so if your signal was low it would not get thru.
We checked everything we could think of. Then asked has anything new been installed in the building recently? The answer was YES, we had a new cola vending machine fitted. Rushed downstairs pulled the plug on the vending computer and the problem went away. It was evenutally traced to a faulty coin mech.
Oh the joys of it all.
