TX-300 300mW FM Transmitter


Posted on Feb 5, 2014

The amplifier has exactly the same architecture as TX500 with the difference that TX300 has only one stage variable VHF amplifier. It is a cute schematic that was made for all of you who wanted something even simpler than TX500 and with not as many necessary parts. It is a perfect circuit for transmitting your music around the house and yard. Inte

resting feature is a gain control P1 that lets you adjust your desired output power and distance. If in case you want to replace Q2 with more powerful transmitter like 2n4427 or 2n3866 you will have to replace P1 with a resistor due to the higher necessary current.
