This kind of problem is either real simple to solve or real difficult there is no in between. I know that is not very technical, but it sometimes it is the nature or RFI. If you try any fixes, do them one at a time. This way we will know which one works. It is strange that all three radio do the same thing. If you have no UPS, how about battery powering the K1 or the other radios and see if the problem is still there. Again, we are trying to see if it a radiated or conducted problem. I am assuming that the radios and the computers do not share the same ac power circuit. If I am wrong separate them Good Luck [you are going to need it!!] George
