AM Receiver for Aircraft Communications - This receiver is controlled by a
Frequency Synthesizer Circuit. The receiver is VERY stable, low noise-level and easy
to build and tune… |
|
AM/FM/SW active antenna - This circuit shows an active antenna that can be used
for AM, FM, and shortwave SW. On shortwave band this active antenna is comparable to
a20 to30 foot wire antenna. This circuit uses receivers that use untuned wire
antennas, such as inexpensive units and car radios....(diagram added 05/06/07)

AN-502: Designing a Superheterodyne Receiver using an IF Sampling Diversity Chipset -
AN-502 Analog Devices Application Notes....[App Note] The AD6600/AD6620 Chipset
Simplifies Receiver Design |

AN714: Wireless Home Security Implementing Keeloq® & the Picmicro® MicroController -
Microchip Application Note Published 12-Oct-99....[App Note] |
|
AN758: Using the MCP2150 to Add IRDA® Standard Wireless Connectivity - Microchip
Application Note Published 4-Jun-01 (app note added 2/06) |
|
AN959: Using the PIC16f639 Mcu for Smart Wireless Applications - Microchip
Application Note Published 10-Nov-04....[App Note] |

Basic RF Oscillator #1 - This basic circuit is eash to build and the components
are not critical. Most of them can be found in your junk parts box…. [Tony van
Roon's circuit] |
|
Bipolar Regenerative Receiver - Contrary to what some radio experimenters think,
a bipolar regenerative design can be made to work efficiently. The major concern is the
low input impedance of the detector-amplifier bipolar…. [Circuit designed by Ramon Vargas] |
Bug Detector (mini) - This project is a handy piece of TEST EQUIPMENT. You can
never have enough assistance when designing FM bugs. The first thing you need to
know after putting a bug together is the fact it is transmitting.
This project gives you this indication. Once you know a bug is transmitting, you can work
on getting the best output power and adjusting the frequency to a blank spot on the dial.
(schematic added 04/09) |

Bug Detector with Beep - This circuit is not open for discussion. Although
working perfectly, it was experimental. I will answer no emails in regards to this
circuit. If you are looking for a more serious and reliable bug detector, …. [Tony
van Roon's circuit] |

Build your own Superheterodyne Receiver - 08/01/96 EDN-Design Ideas....Cell
phones aren't only devices to benefit from eversmaller and more highly integrated
communications-IC technology. The simple, three-IC superheterodyne radio in Figure 1 can
receive stations in 4.5to 10-MHz range from around world with only a 10-ft
antenna. A superheterodyne radio works by mixing incoming RF signal with a
local-oscillator.... [Design Idea by Steven Hageman, Hewlett-Packard, Santa Rosa, CA] |
