Intruders are becoming endemic on all the hf bands, not just top band. Every morning I hear SSB stations on the low end of 80m and 40m, and the worst of all are 10m-12m, which have become a nightmare of swishing signals, carriers, buzzing sounds and illegal CBers. I hadn't realized how bad the situation had become till I could see the spectrum on my Flex transceiver. Most ot the problem seems to be coming from the North in the afternoon, when those bands are open into Asia. I can't imagine how bad all this crap must sound to our JA friends. 73, Jim W8ZR
