I had that problem with my keyboard years ago, and I substituted the cord with a shielded one, and added extra power filtering to the 5 V line inside the keyboard, with three ceramic caps (1 nF + 10 nF + 100 nF) in parallel to ground and a VK??? RF choke in series. With the keyboard unplugged, I had no RFI. It was one of those aluminum foil shield cables...using a copper braid shielded cable as substitute it is inmune to RFI. 73 de Jose, CO2JA __________________________________________________ Do You Yahoo!?
