I have strong interference coming from ( i think ) the cable line that is run into the house for the TV and computer but it's not always on the same channel. I have went threw the house and cut power off to each room at the breaker box with no change. The only time it has ever stopped completely is when the power is out all over the area ( cable service as well ) and then the radio is quiet. I have traced the noise to the cable line coming into the house but i dont know who to fix this problem. The antenna is a Imax 2000 40 feet up with good coax and it is well grounded. I was hoping that someone here may have had this problem as well and might know a fix. Thanks!

Set a scanner or two meter radio to 145.25,and see how strong the sigal is on catv channel 18.Good indicator of cable leakage.

if you actually are receiving noise from the cable line, call the cable company.....it is THEIR responsibility to make sure THEY are not causing RFI.

Actually Ch 18 has a center carry of 147Mhz or so my Natiowide list from work (local cable company tells me).
What radio channels do you notice the most interference on??
