Simple Circuit Detects Current Pulses - 01/06/94 EDN-Design Ideas....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.... [Design Idea by Richard
McGillivray, Grey Bruce Regional Health Centre, Owen Sound, Ontario, Canada] |

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. .... |

Single Chip Builds Tiny Aircraft Receiver - 09/25/97 EDN-Design Ideas....It's
easy to become bored spending time in airports. After all, you can do only so much work on
a notebook computer with no reference material around. So, relax and have some fun at the
airport--build the tiny, single-chip, aircraft-band radio in.... [Design Idea by Steve
Hageman, Hewlett-Packard, Santa Rosa, CA] |

SOP Receiver - .... |

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…. [from Harry Lythall's
website] |

SW Receiver using the ZN416 - A Short Wave Receiver based on the MK484 (formerly
ZN414) that includes the tropical bands and 49 metre bands. [Andy Collison] |
|
SW RF Pre-Amplifier - A radio frequency amplifier to boost SW reception.
Frequency range approximately 5 to 20 MHz. (circuit added 08/03) [Andy Collison] |

Synthesized HF Receiver - This receiver was originally designed for simplicity
and low cost, but, like other projects, it grew. My receiver is now synthesized and the
performance is quite comparable to many commercial designs. The unusual features of this
design are: * Common AF transistors and AF circuitry have been
used for the IF amp, in a transformerless design. This aids construction and
stability.; * IF bandwidth is restricted by conventional L.C.
tuned circuits which are not damped by any resistive or active devices. This gives a
performance, even for CW working. The IF is 500KHz and NOT 465KHz.;
* Options for three different Local Oscillators. I used a Marconi Sig.Gen. with this
receiver for over a year, before I overcame lethargy and built a decent LO.... [Design by
Harry Lythall - SM0VPO] |
