Thanks for the replies. I don't have much experience in tackling these kind of jobs but I do have a connector cable lying around that I used to use to connect a Timewave Navigator with a Kenwood TS-570 a few years ago. I'm going to use this as teh basis for the 847/Ti-3000 cable. Can I use an electrolytic capacitor as a blocking capacitor..??
