Designing an AM Receiver For Low Power Wireless Systems Using the NEC UPC2768GR IC 7/22/96  -  Application Note California Eastern Laboratories Doc #921....[App Note]
DIY remote control based on PIC -  Control up to 8 devices by this easy constructable remote control. It can work as a radio or infrared remote control, depending on the components. Each device output can be configured to be momentary (turned on while you press the button) or latched. Latched outputs can be toggled on/off by one button per channel, or turned on and off by two buttons per channel…. [Peter Jakab, Electrical Engineer, Engineer of Informatics]
DRCS: CLC5526/CLC5956/CLC5902 Diversity Receiver Chipset -  National Semiconductor Application Note....[App Note]
DTMF RECEIVER -  Today, most telephone equipment use a DTMF receiver IC. One common DTMF receiver IC is the Motorola MT8870 that is widely used in electronic communications circuits. The MT8870 is an 18-pin IC. It is used in telephones and a variety of other applications.. ….(design added 11/08)
Dual-Mode Whistler Receiver -  This portable receiver may be completely powered by a recorder or other device designed to use button microphones or it can use its internal battery to provide headphone listening. I decided to see if I could increase the values on the notch filter like that used in the computer-powered receiver above by nearly a factor of 10. Since this receiver will be able to....(electronic design added (6/07)

Experimental fiber optic receiver -  (schematic / circuit added 6/07)
Experiments with Detector Diodes -  When building crystal radios or other simple receivers, the experimenter often wonders about the relative performance of the different diodes in the junk box. Here are the results of several experiments using the typical ….(added 04/05/06)
Exploit Digital Advantages in an SSB Receiver -  AN-302-Analog Device Application Notes....[App Note]  
External Antenna for the GPS-38 Magellan 2000 or Eagle Explorer GPS Receivers -  (circuit / schematic design added 6/06)
Feedback FM Receiver -  …(electroninc design added 04/05/06)
Fibreoptic receiver -  Schematic only, no circuit description
FM Band Monaural Transmitter -  (Circuit design added 8/03)
FM Band PreAmplifier -  (circuit / schematic design added 6/06)
FM Booster -  ....
FM bug -  Schematic only, no circuit description
FM Microphone -  A micro-transmitter is so small and sensitive, it have only 8 easy-to-get parts and can be assembled in one hour….
FM Oscillator -  ASCII format (Circuit design added 10/06)
FM Portable -  …(schematic added 04/05/06)
FM radio (may be used with PC) Circuit -  …....
FM Radio Microphone with Internal Loop Antenna (Area 50) -  This article began as a design guide for hyper cranial erogenic field generators, however, your primitive earth brains are completely unable to respond to erogenic fields in the 100MHz region. I personally had a brain upgrade (for purely medical purposes of course) so I am able to respond....(schematic / circuit added 4/08)
FM Radio Receiver -  Frequency adjustment is accomplished with BB105 varicap diode....
FM Radio Transmitter (David Sayles) -  This small transmitter uses a Hartley type oscillator. Normally the capacitor in the tank circuit would connect at the base of the transistor, but at VHF the base emitter capacitance of the transistor acts as a short circuit, so in effect, it still is. The coil is four turns of 18swg wire wound around a quarter inch former. The aerial tap is about one and a half turns from the supply end. Audio sensitivity is very good when used with an ECM type microphone insert.
FM Radio Transmitters with Opamp -  An low power FM Transmitter using an op-amp as the audio preamp and a single transistor as the RF amplifier…. [Designed by Kamran Ahmed]
FM Receiver Using MPF102 -  An FM regenerative receiver using a single FET and one audio amplifier IC….
FM Receivers -  Here is how you make a superregenerative circuit. Choose a regenerative amplifier circuit configuration that requires more current during oscillations than when not oscillating. Adjust the regenerative amplifier to oscillate. Add a small circuit that uses the current of the amplifier to charge a capacitor while oscillations are taking place. Once the capacitor is charged, the voltage on....
FM Remote Speaker System -  National Semiconductor Application Note  (app note added 07/08/09)
FM RF Remote Control 88-108 MHz -  1KM Range  (added 6/06)
FM Stereo Modulator -  ....
