15 W FM Transmitter

The range/distance: On GP antenna 3 to 4 KM. On dipole antenna 15 KMs (Guaranteed if our dipole is used). With Yagi antenna 20 KMs. Homemade Yagi antenna design only given to fabricate at home. All China make false claims. Their 15 watt is in fact 5 watts only does not give even 2 KMs.
Please note all antennas are optional at extra cost.

This unit includes all the components and circuit boards fully tested and assembled inside a box. Other items include, BNC connector at the transmitter, & audio cable
 Power supply not included required  a 12 volt, 3-10A SMPS power supply with DC pin.

The  15 W FM transmitter has a control panel with a dot matrix LCD display screen and  3 key buttons to change frequency, volume and range by changing the output transmitting power.
Control panel: 58 x 36 mm (as shown in the picture)

Transmitter  key features:
1, Digital technology, make the frequency more stable, the frequency does not change with the environment and produce frequency drift.
No need for any adjustment inside. We give circuit diagram for service at the user end
2, But the frequency can be adjusted digitally by buttons within the specified scope.
3, Use any external audio feed into the aux socket.—

4, Also with the microphone input interface. With 2 mics stereo transmission can be done. All control through a digital potentiometer. It is easy to control the volume of the microphone (supplied at extra optional).
5, Audio input ay aux also by a digital potentiometer to adjust the volume.
6, Transmitting Power can be changed between 0.5 W to 15 W maximum having continuous adjustments features to adjust the range from 100 meters onwards.
7, The power output network for harmonic suppression is very good, so as to make the output spectrum cleaner.
8, Set the frequency and power once and the next time boot does not need to do the set up again!

Main parameters:
1, The input voltage: dc 12 v
2, Maximum input current about 2.5 A at 12 v DC (Optional extra)
3, The audio signal: the maximum input Vpp is less than 1 v.
4, Microphone types accepted: Any
cylindrical microphone or condenser microphones.
5, The output power: 0.5 W – 15 W continuously adjustable!
6, The output impedance: 50 Ω for antenna
7, Working frequency range: 76 m – 108 MHZ
8, Frequency step of 0.1 MHz for adjusting
9, The distortion degree: 0.03% ~ 0.1%

FAQ:–

How far (long) the transmitter will cover?

The transmission range depends on many factors. The true distance is based on the antenna installing height, antenna gain, using an environment facing buildings and other obstructions, the sensitivity of the receiver and antenna of the receiver. Installing the antenna at a higher height and using in away from cities, the distance will much longer.

EXAMPLE:- 15 W FM Transmitter used in the city and village with GP  vs Yagi antenna:

I have many customers in India who use our this 15W FM stereo transmitter with a home built GP antenna and they have tested it with a car FM radio (not cell phone FM radio) and, it covers a good range in a city area with clear sound and no hissing noise.  The distance can be high while using a homemade directional Yagi antenna.

Most Important
Antenna either Yagi, Dipole or GP (ground plane) must be used in this transmitter with 50 ohms coaxial cable RG58( Not the type used by cable tv operators). Cable and antenna are available at extra cost
