- Crystal Radio Set Systems: Design, Measurement and Improvement - Original technical Articles related to crystal radio, impedance matching, diode detection and measurement, headphone measurement etc. The first Article was published around the middle of 1999.
Quick summaries of some Articles:
Article #26 describes construction and measurement of a very low loss single-tuned crystal set with the uncommon property of a reltively constant -3 dB RF bandwidth actoss the MW band.
I believe the first published discussion of the necessity of having the DC load on a diode detector equal in magnitude to the absolute value of the average AC load, for low distortion on strong signals, is explained in Article #1.
Article #2 describes an original convenient device for determining the best source resistance from which to drive headphones or speakers.
Article #15 shows original equations relating diode detector insertion power loss to diode parameters. It introduces the concept of the "Linear to Square-Law Crossover Point" for diode deteectors and shows how it may be used.
Article #27 presents measurements of diode detector insertion power loss as a function of type of diode. I believe the approach is original.
