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

Receiver Building Blocks - (electronic schematic / circuit added 4/02)

Receiving Converters 88-108 Mc to AM broADCast band - I designed this circuit. It can be connected to an FM tuner to play FM stations on an AM radio. (schematic added 6/070

RF receiver circuit - (electronic circuit added 4/05)

RX3302 receiver module schematic - (schematic / circuit added 6/07)

Several Receiver Circuits - (circuit design added 8/03)

Simple Circuit Detects Current Pulses - 01/06/94 EDN-Design Ideas / (added 3/03) The pulse detector provides a visible indication of positive and negative current pulses. The pulses amplitudes can vary from20 to150 mA. The pulses durations can range from10 to40 msec, and their repetition rate can span40 to180 pulses/minute.

Simple Crystal Radio - The crystal radio gets its name from the galena crystal (lead sulfide) used to rectify the signals. A "cat's whisker" wire contact was moved about the surface of the crystal until a diode junction was formed. The 1N34A germanium diode ….(added 04/05/06)

Simple Two-transistor Radio - Here is a simple radio that was designed to minimize unusual parts; there isn't even a detector diode! The sensitivity isn't as high as the one-transistor reflex but the simplicity is attractive. Strong stations will provide plenty of volume ....(electronic design added 05/06/07)

Simple Wireless Radio Data Link - This is a description of a very simple unit designed and constructed for use as a wireless data connection between two nearby computers. The error rate is excellent over short runs, and the transmission speed means that a useful PPP link can be established between the machines. Which are, of course, running Linux..... (added 6/06)

Simplified Modern Converter - Here is as simplified design of the above converter. This is much easier to build. (schematic added 6/07)

Single Chip Builds Tiny Aircraft Receiver - 09/25/97 EDN-Design Ideas / (added 3/03)

SOP Direct Conversion Receiver - (electronic schematic / circuit added 4/02)

SOP Receiver - (electronic Circuit / Schematic added 10/04)

SSB AF Filter - This is a simple filter that restricts the LF response a little as well providing quite a heavy HF roll-off. The prototype has enhanced a Yaesu FT101B that was only fitted with an AM IF filter. The IC is an LM358. (added 02/05)

SSB modulator covers HF band - 09/30/99 EDN-Design Ideas / (added 2/06)

Super 80 Ultra Simple SSB Receiver for 3.5 MHz - (electronic design / schematic added 2/05)

Superregenerative Air Band Radio (Area 50) - (circuit added 07/07/07)

Superregenerative FM Receiver - Superregenerative FM receiver which used 2SK241 (circuit added 08/07/06)

SW Receiver Using MK414 - ….(electronic schematic added 03/08)

SW Receiver using the ZN415 - (electronic schematic / circuit added 4/02)

SWatt RF PreAmplifier - (electronic schematic / circuit added 4/02)

Synthesized HF Receiver - (circuit design added 8/03)
