9G. Install R16, a 100 ohm resistor (brown-black-brown).
10G. Install R11, a 470 ohm stand up resistor (yellow-violet brown). Be
sure to install it exactly as shown in the parts layout. We will be using the
exposed end later during testing procedures.
11G. Install R36, a 270 ohm resistor (red-violet-brown).
12G. Install R40, a 10K ohm stand up resistor (brown-black-orange).
13G. Install R32, another 270 ohm resistor (red-violet-brown).
14G. Install R73, a 51 ohm stand up resistor (green-brown-black). This
resistor is used on the RF output of U6 to give the BA1404 a resistive load
to drive.
15G. Install R30, a 270 ohm resistor (red-violet-brown).
16G. Install U2, the MC145170 PLL. Make sure that the dot or tab indicat-
ing pin 1 is in the same direction as shown in the parts layout diagram.
Solder all 16 pins.
17G. Install R8, a 10K ohm resistor (brown-black-orange).
18G. Flip the board over and find the hole where the whip antenna
mounts. Insert the antenna screw (4-40X1/4) into the hole so that the
threads are pointing to the parts side of the board. Use ample heat to sol-
der the screw in place. You may scrape off some of the screw’s plating to
make it solder better.
19G. Install L3, one of the 4 turn 40nH coils.
20G. Install L2, another 4 turn 40nH coil.
21G. Install L5, yet another 4 turn 40nH coils.
22G. Install L6, the last 4 turn 40nH coil.
23G. Install L4, the custom wound coil that you made earlier. Make sure to
mount this part low to the board and that you are soldering to the copper
of the wire and not the insulation.
24G. Install C31, a 47pF ceramic capacitor (marked 47 or 47K).
25G. Install C30, a 75pF ceramic capacitor (marked 75 or 75K).
26G. Install C29, a 47pF ceramic capacitor (marked 47 or 47K).
27G. Install C9, a .1uF ceramic capacitor (marked .1 or 104).
28G Install C14, a .001uF ceramic capacitor (marked .001, or 102).
