1Km FM Transmitter With UA741 Opamp
Posted on Wednesday, February 10, 2021   •   Category: FM Transmitters

1Km FM Transmitter With UA741 Opamp

This project is the construction of FM transmitter circuit for commercial radio frequencies between 88 MHz and 108 MHz. The transmitter is easy to build and offers good frequency stability through the usage of UA741 oamp. 1Km range can be achieved when powered by 9V battery with 30cm long telescopic antenna.

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]
