15. Install a 100K Ohm resistor in location R8.
16. Install the 470 Ohm resistor (yellow-violet-brown) at R2.
17. Install the 1K Ohm (brown-black-red) resistor in location R3.
18. Install a 1K Ohm resistor in location R12.
19. Install a 1K Ohm resistor in location R13.
20. Install a 2.2K Ohm (red-red-red) resistor in location R4.
21. Install a 2.2K Ohm resistor in location R5.
22. If you plan to use your ID-O-Matic II with a handheld transceiver, install a 2.2K Ohm resistor
at R10. Be sure to see the section below, “Fixing R10”.
23. Install the 4.7K Ohm (yellow-violet-red) resistor in location R9.
24. Install a 100 Ohm (brown-black-brown) resistor in location R11.
25. Install the 15K Ohm (brown-green-orange) resistor in location R14.
26. Install the two square blue trimmer potentiometers in the ID_VOL and IN_VOL locations. Be
sure to get them properly oriented, with the 1 & 3 markings are toward the bottom of the board
(closer to Q2).
27. Install the 78L05 voltage regulator in location U1. Check for proper orientation with outline
on board. Be sure to check the marking to ensure you have the 78L05, and not one of the
2N7000s.
28. Install 2N7000 MOSFET transistors in locations Q1 through Q6. Make sure the transistors are
oriented with the flat side as shown on the board. Double check to make sure you don’t
accidentally grab the 78L05 regulator.
29. Install a the 220 uF electrolytic capacitor at C5. Make sure the lead goes into the
marked hole.
30. Install the 100 uF electrolytic capacitor at C7. Again, make sure the longer lead is in the +
marked hole.
31. Install the 18-pin IC socket in location U2. M make sure the notch in one end of the socket is
positioned to match the board outline. Do not install the chip yet.
32. Install the 8-pin IC socket in location U3. Again, make sure the notch is oriented as indicated
by the marking on the PCB. Do not install the chip yet.
