[ ]
Install the J176 JFET at Q7
[ ]
Install diodes D2, D3, and D4. Note cathode ends (bar) so they are installed correctly. The
anode of D3 and the cathode of D2 should be the non-grounded ends.
[ ]
Install the two test points provided for the R14 location, then install R14. Using these test
points allows R14 to be easily removed and replaced should the audio level during transmit
not be set to your liking.
[ ]
Install resistors R15 and R16.
[ ]
Install capacitors C12 and C13.
Your PCB should look like that shown in the next figure.
