I was plagued by a similar problem, setting off the hardwired, monitored smoke alarm when operating on 80m and 15m. Too solve the problem, I had to follow a couple steps. First attempt was to install

Hello My neighbor has a Polk subwoofer as part of his home theater system. Unfortunately any time I transmit with more than 40W of power on any frequency from 1.8 to 28 MHz, it is audible through the

I would love to put this sub in a bucket of water twice and take it out once, that is a cure for a lot of these poorly designed consumer RFI problems.  I don't have a big enough bucket! Contacted Pol
