A simple FM transmitter circuit powered by a 9 volt battery pretty small SMD resistors used in PCBs
Your offer is very simple compacts zhuchok transmission signal with a range of 100-150m good sensitivity and low current consumption. scheme consists of a bass amplifier for the first transistor and the proper frequency generator in the second. transmitter divided transitional capacitor that allows you to set up a cascade separately.
At that shows the value of all the details and transistors! Reel contains 5 turns enamelled wires 0.35mm to send a diameter of 3.2mm (rod of the handle or auger).Setting devaysa boils down to the installation shown in the pattern of voltages through appropriate resistors, and then check the current consumption – it should be about 10mA antenna – a piece of wire 40cm. Here you can see the bug assembly factory performance
