I have a completely blind friend that see/s complete darkness. So he listens to his AM FM radio to be connected with the world. His brother installed a led ceiling light in his kitchen and now he can,t get the local am stations when the light is turned on. The radio is a portable sony am fm cassette radio. So am asking if anyone knows how to solve the interference problem or if there is some kind of filter to get for him. As long as the light is turned off the radio works fine. The only way he knows if the light is on is feeling the switch position.
