Circuits Designed by Dave Johnson, P.E. :

Low Power 40KHz Light Receiver
Drawing only 100uA, this circuit provides high sensitivity with excellent ambient light immunity.

Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:

I.F. Amplifier - The I.F. transformer primary has 18 turns, the secondary winding has 4 turns. The capacitors across the IFT primaries are 82pF. The input/output transformer has 12 turns, tapped at 3 turns from ground. This transformer is wound on a ferrite core. The mosfets are 3SK45's. The diodes in the product detector are 1N34's. I use a six pole SSB filter from a scrap CB. The centre frequency is 7.8MHz. The -6db bandwidth is about 2.5KHz....

ISM Receiver with TDA5100/ TDA5200 - ....

JT-MB-C in Low Noise, High Isolation Line Receiver for Low-Z Sources - AS035 Jenson Transformer Application Note (app note 11/02)

LF to HF Converter - This converter allows reception of signals below 500 kHz on a 3.5 – 4 MHz HF receiver. It should therefore be useful for those with receivers that do not receive the lower frequencies….amateur radio construction projects…. [from Peter Parker's website]

Light beam receiver - Schematic only, no circuit description

Lightening Detector - A VLF receiver tuned to 300 kHz designed to detect the crackle of approaching lightning. A bright lamp flashes in synchrony with the lightning bolts indicating the proximity and intensity of the storm. It has a superior RF section with a single resonance near 300kHz and plenty of sensitivity. The antenna is a telescopic antenna that extends to two or three feet(added 10/04) [Circuit designed by Charles Wenzel]
