Hi everyone. I'm new to amateur radio and I'm having difficulty with noise. It's only on certain frequencies, but several frequencies. It's on my Yaesu FTM-400. I've put toroids on my power line to the Yaesu, the antenna, the UPS for my computer, and my refrigerator. I thought turning off the computer worked for a minute, but then I was getting noise again. I can turn up the squelch to like 60-80% to get rid of the vast majority of it, but that doesn't seem like the best solution. Any ideas what I can do? antenna is a Slim Jim role up j-pole. I had it hanging on the wall near a power outlet, but I just moved it to my closet door away from power and there was no change. Here are some videos of the noise: Anyway, I'm hoping my tech call sign shows up in the ULS today. this is kind of a frustrating start.
