Default Re: Pye 75 repair Scotland

I had a terrible problem with very bad interference about 18 months ago.
At one time it seemed to be the power supply for a TV Scart to RF converter box, after I replaced a capacitor in the PSU it cured the problem briefly.
But it started up again, more or less obliterating MW on all my radios which used a long aerial. It was also picked up to a lesser extent on a portable radio.
It turned out to be the power supply for a 3D printer in my sons bedroom. I fitted a common mode choke in the DC supply from the switched mode PSU to the printer and it stopped the interference.
I am not saying you have a 3D printer, but it is amazing what different new electrical items get added to a home which can cause interference.
It may even be caused by something generating the noise from next door.

You can try wandering around with a portable MW radio and see if the interference gets worse or better, but it may not as it could be in all of the house electrical wiring.

Alternatively go around disconnecting all items from the mains apart from one radio, which receives the interference, to see if any of them are causing the interference.
