The Popular Electronics Heterodyne Detector

detector recordings notes

The Detector

A good and short exposition of the heterodyne principle can be found on the hyperphysics site Here is the original schematic again, redrawn in a format matching the other detectors in the "Fall 2000 lineup" experiments: schematic diagram and parts list.

If you have built this kit, or are planning to, please let webmaster@central-jersey-sas.org know so we can include your experience (and experiments) in the Experiments section.

This detector was built by Mark Streitman -- and is working. So some time we will get pictures and recordings of it in the Experiments section.
