Thanks for the information, I guess I must be in the dark ages here.
The signal that interfers here could be at 16 khz, it's kind of a
broad signal, about 3 khz wide so it's kind of hard to tell exactly
what the freq is. I have tried all of the tv's and monitors here.
This signal starts up around 10 AM weekdays and goes of around 1 PM,
but it varies, on weekends I've heard it at 0830, so it's really hard
to track down. I suspect computer modem in the area.
