Group Description

The forum to find out about and discuss Synchronous AM Demodulators - designs, experiments, commercial products, adaptations of commercial radios, and results. Synch and quasi-synch AM demodulators are superior to conventional envelope detectors for the detection of amplitude modulation on radio frequency carriers, especially in the presence of selective fading, as experienced when signals travel by ionospheric propagation. They have proven to be of great value in the reception of shortwave broadcasting and are included in several superior radios.
