Circuit diagram of the FM radio transmitter for the range 88-108 MHz, power supply 12V (KT3102, KT610) This transmitter can be used to organize local radio broadcasting within a very small zone of confident reception. For example, in the conditions of a tourist center, camping, children's sports and health camp, in the conditions of another enterprise of active recreation, located in a forest or other natural area, remote from populated areas. Frameless inductance coils. Wound with copper winding wire with a diameter of 0.6-0.7 mm. Winding is done on a temporary mandrel, which after winding and forming the leads is removed from the coil. The role of the mandrel can be played by the shank of an ordinary drill of the corresponding diameter. The diameter of the mandrel for L1 is 5.5 mm, the number of turns is 4. The diameter of the mandrel for L3 is 5.5 mm, the number of turns is 6. The diameter of the mandrel for L4 is 7.5 mm, the number of turns is 5. The coil L2 is a choke wound with a wire PEW 0.12 on a constant resistor with a resistance of more than 50 kOhm and a power of 0.5 W. Contains 30 turns.
