I used 4 to 5 turns on a Ferrite #0475167281 clamp-on bead. Basically I wrapped as many turns as the bead would accept. I did that to each and every electronic device.

As a side note, I managed to whack my laptop PC this weekend during the ARRL DX CW contest running 1kW on both 40 & 20 meters. The desktop station PC was not affected. I turned off the laptop and set it aside.
