There's a couple of questions about the CATV theory:
1.) You mentioned that you heard voices like a DJ. I've had digital cable
and on the music channels they carry, there are no voices or commercials.
2.) I'd expect you'd hear programming other than music? Is that the case?
And does it show up in just one place?
3.) If the CATV system is leaking, then you will get into it. So fire up
the amplifier and start pumping some Watts in the direction of the cable
lines. It's not your fault if you get in. But if you are, I can almost
guarantee you they will be out quickly to fix the problem as they are
supposed to be a closed up system.
It's certainly an odd problem.....
