CB Transmitter -  For the regulation it needs a voltmeter (with needle better) and charge 50W/5W. Connect charge 50W in the place of aerial, with the voltmeter in the exit voltmeter. Be supplied the transmitter with + 12V. It will be supposed we have consumption between 0,7-1A. With a screwdriver we regulate the core of inductor L1/L2 and later the variable C6 until we see the biggest tendency. We connect the microphone and speaking we observe the clue in the multimeter. If all have become right will be supposed the tendency, speaking, to go up roughly 30-35%.

Earwig -FM Transmitter -  This is an easy to build FM transmitter that fits into a matchbox. It transmits to any standard FM radio and can be used around the home as a baby minder or outdoors for up to 300 metres. Its sen­sitivity and clarity are very impressive -even the ticking of a clock can be picked up 3 metres away. Almost everyone has the ambition to use the airwaves. Whether it be for remote control or transmitting halfway around the world, we all love to broad­cast. electronic schematic added 05/08)
