My DH is a ham operator and it could be that. Ham operators should have filters on their equipment to avoid this problem. Most new ones now have them built in. I don't know about CBers. However, we have a walkie-talkie set up and every now and then it blurts out but it is not coming from the radios. My DH has four antennas set up and never had a complaint. Aside from that, when I first moved in my home, after we had gone to bed, I could hear music (very softly) playing. I would get up, check everything, and finally figured it out. It was coming out of the faucet in the half-bath! Radio transmissions can do weird things. A relative that lived in Torrance CA back in the 60's could pick up the station KOMA here in OKC. Now that is a hugh bounce.
