Martin It sounds like the switching power supply is still active, even when the computer is switched off. I suggest an external switch which can be used to completely kill the computer until you actually want to use it. Good luck and 73 Bob N6WG The Little Station with Attitude

On 160m, snap-on ferrites on 2 network-cables completely removed the carriers. On 80m the problem seems to be more difficult: The noise is produced by one of 3 Computers in my buro, even when it is switched off. The other computers are quiet, also the one in the shack. The noise becomes a lot stronger when the computer is on, but only completely disappears when it is disconnected from the mains. Its a raspy carrier slowly sweeping up and down the band. Any ideas where to start? A snap-on ferrite on the power-cord helps a little, but not much. -- Best regards, Martin DM4iM, ex DL1iAQ K2 #2706 mailto:[EMAIL PROTECTED] _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
