FM Transmitter with Mic & Line Input
Posted on Friday, September 3, 2010   •   Category: FM Transmitters

FM Transmitter with Mic & Line Input

This is a unique FM transmitter that provides both a built-in sensitive microphone and an RCA jack for line input. It has two modes of operations, "Microphone" and "Line", which are selectable using a jumper. In the "Microphone" mode, it can be used as a wireless microphone transmitter. In the "Line" mode, it can be easily connected to any audio source to broadcast the audio signal to any FM receiver within its range. 500mW FM / VHF Transmitter Amplifier / Booster can be added for longer transmission range.

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]
