• Part 1 - Winding the coil
• Part 3 - Installing antenna and ground

---

   The proto board comes with the LM358 op-amp already installed.

---

   First install the jumpers as shown:
   You will be using bare tinned copper wire for the jumpers.
   The jumpers on the illustration are shown in color to indicate their function:
   RED indicates positive 9 volt power jumpers.
   GREEN indicates negative 9 volt power and ground jumpers.
   YELLOW indicates signal level jumpers.

---

   Next install the resistors as shown.
   Resistors R1 and R3 are installed vertically.
   Resistors R2 and R4 are installed horizontally.

---

   Next install the capacitors as shown.
   Capacitor C7 is a polarized electrolytic capacitor and must be installed with the negative lead in Row 11.
