Unwanted radio station w/ system off

Help...I can hear a local radio station through my speakers when everything is turned off. How can I eliminate this problem.It must be noted I live 3/4 mile away from their antenna.Thanks in advance for your help, Larry
It might be the fillings in your teeth. I saw this once on an episode of Gilligan's Island so I know it is for real.
Yeah, Gilligan is awesome.

The time that meteor crashed on the island the professor made the coolest ass lead suits for Gilligan, the Skipper and himself to wear so the radioactivity wouldn't kill them when they went to inspect it.

Coolest of all were those slit-eyed shades Gilligan had on. I just had to get me a pair of those!
You may not be able to do anything, being you live so close to the tower. You might call the station and ask to talk to a tech. Explain your problem to him, he might be able to filter it out. Be nice, It is your problem not the stations.
Are your speaker cables long? The speaker cables act like an antenna.If they are try to set your speakers closer to your amp with shorter cables. Go buy some cheap speaker cable for a test. Do any of your neighbors experience the same problem? For get trying to use any 120v line filters,it is not coming in through the ac power line.

I hope this helps, Jim
I used to pickup truckers CB's. I switched to shielded speaker cable. The braiding creates used on some of brands Kimber Kable works great.

Good Luck.
thanks guys...its a pleasure to be the brunt of your humor.
speaker length is approx. 10 ft. shielded may be the answer or maybe fishing line. thanks, larry
