   The terminal is connected to slider of VR3(Max. deviation adjast) through
   through C55(1uf).
   You can discriminate the terminal of VCO from VR3.


       TXA ----/\/\/\--II---------- MO VCO
              56kohm  0.1uF

   If you get weary to remove a shielding plate, you may connect TXA to hotend
   of VR3 through R and C as aforesaid.

2. RXA
   connect to pin 12 of IC2.
   IC2 is a hybrid IC for FM IF amp. and detector.
   The IC was not indicated the number of pin.
   You must discriminate the pin from granded pin of IC.
   2 and 16(last) pin is connected to grand.
   

  I connect 2 TNCs to this tranceiver.
  One is 9600bps and oter is Bell 202,1200bps.
