This is NOT a good idea. First, parallel conductor cable is a lousy choice where RFI is a potential issue. Most uses of the AUX I/O connector should use TWISTED PAIRS for immunity from RFI and noise. In general, TWISTING is FAR more important than a cable shield in rejecting RFI and noise. Second, most uses of the AUX I/O connector will require only a few circuits, not all 15 pins. Thus, a FAR better way to do this is buy some DB15 connectors, some CAT5 (or CAT6), and some connector hoods and wire them yourselves. Use one pair per circuit -- for example, for FSK, orange to pin 1, orange/white to pin 5; for PTT, brown to pin 4, brown/white to pin 5. And so on. 73, Jim Brown K9YC _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
