I have this buzzing noise in my house electrical system.

I can hear it in a stereo I have in my Office and I bought my wife a
new clock radio for Christmas and that is up stairs in the bedroom and
it comes through that radio also. These are the only two things I hear
it in. It is a short buzz that last about a second and happens about
every 10-15 seconds.


Do you have one of those electronic rodent or insect repellers? Or does one
of your neighbors?
