Tools you need：
①Iron (30W) ②Solder wire ③Multimeter
⑤Wire cutters
1. Install the IC: IC.BH1417F corresponds to the silk screen on PCB Note that the welding pin must not be short circuited
R F - 0 3 P L L Stereo FM Transmitter kit instructions
Precautions:
④Twe ez er s
①Check part values & quantities against part list ②Always meter resistor values before soldering ③Understand all part polarities and orientations
2.Install the diode： 3. Installation resistance （bend is a zener diode 4.3V.Vertical Fit the 24 resistors on the PCB according is the variable capacitance diode FV1043） to the resistance values on the PCB ZD1 to 4.3V.VD1 to FV1043 Notice the direction of the diode

RF-03PLL Stereo FM Transmitter component list
5 .Install ceramic capacitors：
6 . Install LED：
7 . Install triode:
Install the 21 capacitor on the Install the red LED to LED1 S9014 into Q1 PCB according to the parameters Note the positive and negative of the LED。 S9018 into Q2，Q4，Q5 on the PCB
8. Fit quartz and toggle switch： 7.6MHz quartz into X1 Toggle switch into S2
10 . Insta ll toggle switches to S1 and S2 11 . Buy the battery box red line 9 . Install electrolytic capacitors： Microphone into MIC1 Install 11 electrolytic capacitors on into J1 +, black line into J1 Audio input into JK 1 the PCB. Please refer to PCB's silk screen Batte ry term inal into J1 Note that the polarity of the electrolytic 300mm Wireway into ANT capacitor cannot be reversed。
12 TEST： Check whether the PCB electrolytic capacitor is polarity reversal Are zener diodes and varactor diodes properly soldered Supply DC 4 to 6V。S1 is the power switch LED1 is the power indicator The operating frequency is 87.7-88.9MHz.106.7-107.9MHz Code
