Figure 96. All transmitter parts except for the inductors. Note TS912 orientation, BS170 flat side orientation.
Install the parts in the following order:
Some of the component placements are somewhat confusing. Refer to the above for resistor placements.
U16 - TS912 - 8 pin SOIC dual op-amp –
above. Solder one pin, then double check the orientation before finishing.
R107, R108, R109, R110 – 1 ohm resistors. All four of these resistors are next to each other with C158
on the right side and C160 on the left side.
R111 - 1K
R98 - 7.5K -
Double check parts placement with photo
R100, R101, R104 - 10K
R105 - 15K
R97 - 18K –
Double check parts placement with photo
R95, R106 - 22K
R112 - 39K
R96, R99 - 47K
R103 - 75K
Q9, Q10, Q12 - BSS123 MOSFET switch
Q11, Q15 - FJV3102R
Makes sure U16 is installed with the correct polarization as shown
