Poor Tuner Performance

In the garage I have an older Kenwood amp and separate manual dial tuner.

It's been in the same spot for at least 6 years, same "T" antenna, no electrical changes, nothing else changed.

Noticed this summer that it simply will not pull in the stations that it used to, only a few strong FM stations will light up the "stereo" light.

Today I tried a few other cheap wire antennas, different styles, even an old set of rabbit ears, no improvement.

What would cause it to loose reception!

Older receivers used FET's (field effect transistors) in the front end that go bad with age.
Most of those units had the tuner in a small metal box but it is serviceable.

I was so close to buying a replacement tuner and then discovered today that the reception issue is caused by my new LED garage lights.

Turn the lights on reception disappears, turn them off, great reception.

Fist time I have ever heard of this happening!

Yep LED's and some T5 with the newer electronic ballast will do it too, This has been a problem for garage door openers as well. I ran my radio antenna wire to the outside via quad4 coax to a radio antenna
