Came home tonight to find the following noise started up on 75 meters. Was relatively quiet then BAM! Like someone threw a switch. I captured two screenshots. First is when it first happened then second is after it stabilized, but wider. Seems to go from around 2 to 5 MHz. The peaks are around every 15.5 kHz.
It wipes out 160-10 with the most severe at low frequencies.
My XYL has been directed to leave it unplugged unless ABSOLUTELY necessary to use it.
Another source of interference like it is generated whenever my neighbor returns from a camping trip and plugs his Camper trailer in to recharge the internal house batteries for a couple of days before it goes back into storage. I just live with it. The cost of having good neighbors. (And he doesn't complain about all of my midnight antenna raising projects) If you have a neighbor that has a camper or RV preparing for a trip or just returning from the same, it should disappear in a couple of days!
