I am trying to install my CW interface UCW-100 by Unified Microsystems I for got what I had to rewire and If I plug it into the RCA jack on the back of the OMNI VI Plus. I does not work when I plug it into my 1/8 in key paddle jack. What am I doing wrong? Stay on course, fight a good fight, and keep the faith. Jim K9TF/WA9YSD
