Maybe if you expand the drawing beyond what you show it would make sense. At the
moment it looks to me like you have a loop between the input and output of the
7600 through the splitter. Does the radio normally have a jumper from RX-ANT-OUT
to RX-ANT-IN for it to work correctly? Remember, I do not have a 7600. All I
have is your (incomplete?) description below to work from.
