Features:

Kit includes all components and circuit boards but does not include power supply,antenna,cables,audio cables and coaxial cables

7W FM without any debugging

No matter you are a novice or veteran,as long as you are willing to solder

You can successfully DIY

Control panel components:mainly consists of 51 series microcontroller,dot matrix LCD display and keypad

Components:digital FM radio chip sc3355+9018+2+2+RD15HV sc2053 four-stage high-frequency power amplifier

and power regulation components

Transmitter kit main function

1.DSP+PLL technology,so that the frequency is more stable,the frequency does not change with the environment and frequency drift

2.No need any adjustment,bring DIY fun to beginners

3.Frequency can be adjusted continuously within the specified range

4.With microphone input interface,and can control the microphone volume by digital potentiometer

5.Digital potentiometer audio input to adjust the volume

7.Output power grid is very good at suppressing harmonics,making the output spectrum cleaner

8.Set the frequency and volume of power-down protection,no need to set it again next time you turn on the power

Specification:

1.Input voltage:DC12V

2.Input current:3.0 A

3.Audio signal:Maximum input Vpp less than 1V

4.Microphone type:round microphone or microphone

5.Output power:15W

6.Output impedance:50Ω

7.Operating frequency:76m -108 MHz

8.Frequency of 0.1MHz

9.Deformation degree:0.03%~0.1%

A.Board size: Fireproof board:150*60mm(excluding fins)

Control panel:58*36 mm

B.Transmitting distance:more than 8 kilometers(provided that it is an open field to transmit)

C.Stereo separation:63dB or more

This kit is specially designed for the requirements of beginners

Basically no need to debug,debugging difficulty is basically 0

As long as you follow the correct welding operation

Whether you are a veteran or a novice,you can spend the least money to enjoy the DIY fun of FM amplifier

As for soldering, you do not have to worry too much

This set of capacitors used in the resistor strip are 0805 package

Soldering board and plug-in is the same

This transmitter must use a 50 ohm antenna,frequency of about 100 meters antenna

Do not use a conductor,rod antenna,2.4 G antenna,radio antenna
