tuner/call button

Bill Redshaw
 

Can anyone tell me why the tuner/call button would not key up rig when pushed.  I just get one beep each time pushed. Antenna is connected to an mfj tuner, and has worked for a long time.  I cleaned up the shack and made some changes to hook up between the watt meter and amp and tuner.  I think that it should at least key the rig even if not connected correctly.  Thanks in advance....
