I used the bottom half of the Z-13 or I  guess the Z-11 drawings.  Finally turned on the Master Switch.  The  good news all the smoke stayed in the wires and the fuses didn't  blow.   The radio receives loud and clear.  The only problem is  when I hit the PTT on the SL-30 all I get is a loud squeal, thank goodness  ground control didn't know where it was coming from, where do I start looking,  using the old look for the simple fixes first?  I have the CH stick grips  with the PTT in the trigger portion.  I'm sure that I'm not the first that  has experienced this problem but couldn't find anything in the archives so would  appreciate any helpful suggestions.

Jim,

  

 I had the same thing and it turned out to be a  shorted antenna cable.  Disconnect the cable at both ends and use  an ohm meter to determine if the center connector is shorted to the  ground.  In my case, one of the BNC connectors was shorted.

  

 Hope this helps.

When you hit the trigger, does the SL30 TX light go  on - indicating that the mic was keyed?
