If use a normal DC adapter that low quality, may will have this problem. The Horseshoe-shaped Variable Resistor P1 is used to adjust the strength of the audio input.
The Trimmer -C6 used to adjust the frequency of the transmitter. The output waveforms can be both amplitude and frequency modulated.
It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.
The output power of our transmitter, carrier frequency of our signal, strength of modulating signal and the power gain 2 km fm transmitter our antenna will define the area coverage of the transmitted signal. That is, to construct a device that can broadcast signals on an FM broadcast band and picked up 2 km fm transmitter the receiver.
To review some modern digital technologies that has been developed for effective FM signal generation. To show the design and components of a FM transmitter To show the construction process of an electronically operated system known as FM transmitter capable of transmitting a frequency modulated signal.

This is compounded by the fact that strong FM signals can bleed over into neighboring frequencies making the frequencies unusable with the transmitter.
Some frequencies below Some models which connect via 2 km fm transmitter other than the headphone jack have no means of controlling the volume, which can force the sound to transmit out from the device harshly causing over modulation, audio distortion and possible radio interferenceor too low.
In theory a device could use an automatic level control 2 km fm transmitter audio limiter circuit to overcome this problem although there are few if any devices with such a facility available out on the market yet. Assemble the circuit on a good quality PCB.
The circuit can be powered from anything between 9 to 24V DC. For L1 make 3 turns of 1mm enamelled copper wire on a 10mm diameter plastic former.
