Low cost FM Transmitter under Rs 2000

Supplied in fully assembled form is a finished PCB product duly tested and ready to use in open condition only. One has to do simple fixing if the box and its accessories are taken at an extra price. Antenna and power supply extra. Soldered by skilled hand it works perfectly. One may optionally buy a simple antenna of 300 ohms impedance with twisted pair wire 5 meters as feeder cable but for getting a very long range, choose the FD antenna. Please note the distance coverage in cell phone FM radio is poor compared to receiving on a regular radio or car radio.

It is an advanced hobby circuit board, unlike simple circuits with one or 2 transistors which are for play purposes and not for regular use.
Note if you buy the 2-watt kit:
If you are not confident about assembling yourself opt for other models or our assembled kit model which are all fully assembled and tested
It is based on varicap-controlled frequency selection where frequency drift does not take place, unlike simple circuits that change frequently..
It is mono transmission only with mic input and aux input. Aux cord and mic are not included.
Not advisable to be operated beyond 100 MHz
Frequency adjustment is by pot and no digital display
Delivers harmonics-free output by use of a 4-stage lowpass filter, a special design followed in all professional products in this category.
If not adjusted for use with a matching antenna, the power MOSFET transistor may fail.
RF power output can be read in a simple digital multimeter.
Can be used 24/7, with online customer support
Suitable housing has to be made by the user to accommodate the board but a cooling fan must be used. Alternatively, you may buy them as extra here by choosing them accordingly The kit is supplied without AC to DC adaptor and antenna but can be bought separately
