Our phone service is with Time Warner Cable and all phones in the house cause static on all radios. The static occurs while a phone is in use, stops when we hang up, and then reoccurs for about a second after a short pause. We have different brands of cordless phone and several radios. A Time Warner technician tried his handset and it also caused static on all radios. I've asked the Time Warner customer service department as well as 2 or 3 of their technicians at my house and no one knows how to fix the problem. Any ideas?
