Automatic Repeater - This circuit will be of interest to radio amateur and
anyone possessing two radios, (one of which must be able to transmit i.e. a
transceiver). It is a self powered (audio derived) repeater circuit for receiving a
signal and re-transmitting it via or radio. (added 10/05) |

Basic RF Oscillator #1 - This basic circuit is eash to build and the components
are not critical. Most of them can be found in your junk parts box….(Tony
van Roon's electronic schematic / circuit added 4/02) |

Building a Simple LF Exciter - (circuit design added 8/03) |

Building an RF Remote Control System - (electronic circuit added 04/05) |

Car Anti-Theft Wireless Alarm - This FM radio-controlled antift alarm can be used
with any vehicle having 6to 12-volt DC supply system. The mini VHF, FM transmitter is
fitted in vehicle at night when it is parked in car porch or car park. The
receiver unit with CXA1019, a single IC-based FM radio module, which is freely
available in market at reasonable rate, is kept inside. Receiver is .... (added

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%. |
