Re: A Different Kind of EMC Problem

Following the thread on this discussion reminds me of a problem that I had when I first graduated. I worked in a TV studio equipment RD lab where dc power was wired around the building. At one point I experienced considerable noise problems at the output of a video amplifier function that I

Re: A Different Kind of EMC Problem

Don, and the group, This is not so complex. As you surmise, parts of the house wiring are being switched in and out by devices on it, and the broadcast RF present on the wiring is being modulated by that switching. While probing around the house with an untuned RF detector, I've found power

Re: A Different Kind of EMC Problem

If the problem were emissions, the interference would be very audible with the radio station off the air. Just a rambling thought pattern ... I'm not sure I necessarily agree with this. If the radio carrier drops off, the front end stage and intermediate stages aren't carrying an rf

A Different Kind of EMC Problem

I have three devices in my house that cause problems with AM radio band reception, but not due to emissions, In each case, the device adds modulation to strong AM signals, synchronous with the power line. The three devices are: 1. A stereo adaptor for a Beta VCR, 2. A dishwasher with electronic
