Infared Remote Control Transmitter-Receiver

here's schematics for infared remotes. this remote transmits a tone using an infared led. this tone is decoded by the receiver. since the receiver only switches when it "hears" the tone, there are no accidental activations.infrared remote control schematicsir transmitter schematic:ir receiver schematic:remote control setupto adjust the circui...

Broadcast FM Transmitter 88-108 MHz

the circuit is identical to the wideband fm transmitter but with a few small additions. tr1 (bc547) is an inverted hartley oscillator which based upon an inductor fabricated on the pcb. this makes it megga-stable, and setable anywhere in the vhf fm band (76mhz to 119mhz) and the bb105 varicap makes it voltage tuneable over about 8mhz of that band. the i...

Wideband FM Transmitter 88-108 MHz

this fm transmitter is for the 88mhz to 108 mhz band. this particular tx is of special interest to those wishing to build low power power amplifiers for the vhf bands since it used impedance matching, power amplifier and antenna filtering, all of which should be used by radio constructors, whether it be for amateur radio or any other form of radio.fm ...
