This simple stereo encoder circuit schematic is build with 2 IC MMC4066E and MMC4047 and one transistor BC547B. On IC1 2 and 3 pins is the audio output which is amplified by T1 (current amplification) ...
The high-density ASK (amplitude shift keying) environment is one in which there are so many transmissions occurring at a given frequency that they occasionally collide and thus fail to get properly ...
