TR33 is for the roger beep 
you can install a mini switch on the base or collector leg of that TR33 or if you don't want the RB just cut the collector leg.

I have two of these radios and all I have ever done is cut jumper J9 to defeat the roger beep. You can add a switch if needed to turn on and off, but I never use mine, so I just cut the jumper.
