Hi
Let me add my experiences at this later date.  My wife brought home her iMac 5.1 when her office closed.  She experienced the same screen jumping when I keyed my transmitter (100 watts with antenna just outside in the backyard).  I put the usual toroids around the power line and the keyboard and mouse.  Still jumping.  I tried removing the kb and mouse.  The jumping stopped.  I replaced the mouse, then the kb.  Still no jumping.  My only conclusion is that when the kb and/or mouse were plugged in to certain usb ports, the screen jumped, but when plugged into other usb ports, no problems.  Weird, of course. The toriods are still on the cords, but they are staying.  Except on 80 meters where there is still a prob.
