Re: I have been noticing a 1 second on / 1 second off carrier at 30.53 KHz
intervals on 40 meters.
My washing machine does something very similar to this. The source is very obvious since the carriers rise up and down in time with the washing machine agitator motion. I’m not saying that is what you are hearing, but it just shows that EMI is not a priority for modern appliance designers. It is the first time that I have had a washing machine that has been the source of an EMI problem. I haven’t spent much time trying to figure out how to eliminate it since hitting the washing machine OFF button makes it go away. It was nice of the manufacturer to add that feature ;-)
