The 301 remote tuning knob uses DB25 pins 6 and 8 for the encoder signals. If I run a Y splitter off the Omni 6 DB25 and connect both the 301 and a computer, the 301 stops working. Pins 6 and 8 norma

Barry: What you are describing is not a defect, but a well known fact that you cannot usea serial port to do two jobs. When you use the serial port for computer control, pins 6 and 8are tied togeth
Thanks Carl and Clayton. As suspected, pins 6 and 8 need to be n/c in the cable between Omni 6 and PC. I will be posting info soon to the Ten-Tec Wiki on how to use a 302R remote tuning knob with an
