This is the schematic for an FM transmitter with 3 to 3.5 W output power that can be used between 90 and 110 MHz. Although the stability isn't so bad, a PLL can be used on this circuit. This is a circuit that I've build a few years ago for a frien

PLL bug transmitter This is strictly an educational project explaining how a transmitter works and can be built. This project may well be illegal to use but this is up to you to investigate. This frequency of this transmitter is PLL controlled which

Here is a perfect simple one transistor FM radio to build. Here is a good starter DIY project for anyone interested in audio. This simple radio uses an inductor as both the oscillator circuit and the antenna. It just uses one JFET transistor. There a

STL: a way to feed the audio signal from the studio to launch room, or from a remote feed to the studio equipment. Major manufacturers such as Marti company, SmartiPOT encoder solution, the main products are RPT-40-type RPU transmitter and R-10 type

The PC Board Artwork for The Wasp SENSITIVITY The sensitivity of the WASP depends to a large extent on the value of the load resistor on the electret microphone. We have used 39k in the project, as the microphone we supply is a v

Everybody knows, circulator has one-way transmission character, incident signal can be passed smoothly (insert caustic to be under 1db) , reflection signal is absorbed as a result of resistor be absorptioned and cannot pass (return loss can achieve 6

The PA can be reactive 1-2W

You might be thinking whats the difference? How do they work with my ipod? Which is the best? Well the answer is quite simple. The FM Modulator and FM Transmitter both reproduce an input signal that can be turned into a playable audio signal that you
