How's that for a catchy subject. Here's a question to help my wife from killing me in my sleep!! (Just Kiddin') I bought this nice electric matress pad, (Brand-Spring Air) dual controls, low voltage operation, and everything. Should have been great, huh?? No. It has a pulsating static sound in our baby monitor when power is off to the blanket, and when it is on it's a constant static in the monitor and even messes up the TV! It has a 120VAC in and 14VDC out power supply. I wired up a small box with an in line filter hoping to take care of the problem, but it didn't work. Any ideas?? Why does this happen?? Thank you.
