This is my first attempt in trying to solicit outside help for a solution as I originally thought the problem was with my computer or radio equipment.
Actually you're not soliciting out. This forum is sponsored by OMP.
Anyhow it sounds like your cable is defective. Just call Ikarus tech support at 239-690-0003 and they will get you a new one. This will be the fastest course of action as they want to handle all defective product direct.
Thanks!
