Hi Gord,
First Very Happy Holidays to you! There is nothing wrong with your "Y"
cable, the problem is with a standard 25 pin serial cable. The problem with
this cable is that the computer serial port uses pins 6 and 8 for
handshaking, this could cause the OMNI to do strange things because they use
pins 6 an 8 for the remote tuning knob. My suggestion is to build your own
serial cable using 3 conductor shielded cable. Connect pins 2, 3, and 7 at
both ends.
73,
