27 MHz Transmitter Circuit – 10 Km Range
The 10 km range, 27 MHz transmitter circuit explained here uses citizen’s band which consists of 2 main types of users: radio control (R/C) modellists and users of low-power FM transceivers for local communication. However, here it is designed and intended for testing antennas and aligning receivers. It is actually an AM/FM quartz controlled for […]
10 Simple FM Transmitter Circuit Diagrams Explained
An FM transmitter circuit is a high frequency wireless device which is able to transmit voice signals into atmosphere so that it can be received by a corresponding FM receiver circuit for reproducing the voice signals in a loudspeaker. Here we’ll discuss how to build small FM transmitter circuits using 10 different methods, one that […]
1.5 watt Transmitter Circuit Diagram
This little transmitter will allow you to communicate, chat, send music transmission on any standard FM Radio tuned within the existing band, across a radial distance of not less than 500 meters or half a kilometers. Warning: Using this transmitter could be illegal in your country or area, take appropriate permissions before indulging. How it […]
Simple TV Transmitter Circuit (Audio and Video Combined)
The TV transmitter circuit presented in this post incorporates the European standard FM frequency for audio and Video up-links. Referring to the circuit below, Q1 is configured as a preamplifier for amplifying the audio input to be modulated. Circuit Description Q2 is fundamentally responsible for conducting a couple of important functions: It amplifies the carrier frequency […]
Long Range Transmitter Circuit – 2 to 5 Km Range
The proposed long range transmitter circuit really is very steady, harmonic free design which you can use with standard fm frequencies between 88 and 108 MHz. Technical Specifications of the Transmitter This will likely encompass 5km spectrum (long range). It includes an extremely consistent oscillator for the reason that you employ LM7809 stabilizer that is […]
