This FM Transmitter is stable and has output power of 15-18 watts. You don't have to understand the precise working of the transmitter to build it. But some basic information won't harm. A transmitter alone is, as you probably know, is not enough to start your radio station. In the simplest form you need 4 things. First an input device such as an amplifier you also use with your home stereo. You need a regulated power supply. In this case a 14-18 Volts 2.5-3.5 Ampere. One of the most influential things you need is antenna and coax cable. And finally the transmitter itself. Transmitter is divided into two main parts; the oscillator and the amplifier. The oscillator converts electric sound information into electromagnetic waves. The amplifier gives these waves a bigger amplitude.
Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
