MRX-40 RECEIVER BY STEVE BORNSTEIN

QRPp Summer97

Description: This is the companion receiver to the Micronaut QRPp transmitter that is designed for the low end of 40 Meters. The receiver is a single stage direct conversion using a 7.048 MHz crystal, NE612, and LM380 on a 42 by 22 pc board.


A SYNTHESIZED 2-METER FM RECEIVER WITH PC CONTROL BY STEVE HAGEMAN

QST Feb99

Description: The receiver is built around a MC13135 IC with a PLL LO SYNTHESIZER using MC145170P2. The computer interface and control is done with a PIC16C73 uP which also drives a 16 character 2 line LCD display, an Optrex DMC16207N-B. The PC program to run Windows 95/98 and the source code for the PIC uP is available under hag2mrx.zip from ARRL http:/www.arrl.org/files/. Other ICs required: LM2931AZ and LM386.


A 40 METER RECEIVER BY THOMAS DUNCUN (2 BD SET)

73's Feb99

Description: This is a well designed double conversion AM/CW/SSB receiver that covers 6.5 to 7.5 Mhz. The design uses an SBL-L for the two mixers, an MAR-1 for the front end amplifier, two MC1350 IC's, an NE602 for the detector and three stages of MC1458 for the audio. The project is built on two boards. If you are looking for a good receiver to build, this is the one

QST Mar 01

Description: this is a simple TRF receiver for tracking the source of HF RFI and operates around 136 MHz. The circuit consist of MRF901, J310,and LM358 and operates from a 9 v battery.


THE WBR RECEIVER BY DAN WISSELL

QST Aug01

Description: This is the Colpitts regenerative receiver. The circuit uses 2N3904, MPF102 78L05 and LM386 IC. The receiver covers 5 to 15 Mhz.


ONE TRANSISTOR RADIO BY MITZ

Description: The project is assembled on a 3.125" x 2.5" PC board. The circuit uses 2N4416 FET and a TL431CPL Voltage controlled Zener. The radio tunes the FM broadcast band. http://www.somerset.net/arm/fm_only_one_transistor_radio.html


HIGH PERFORMANCE REGEN ARMSTRONG S/W RECEIVER BY CRIPE

73's Oct95

Customer Comment: I built the Armstrong Update regenerative receiver from Dave Cripe's article. As promised, the 1496 detector produced uncommonly smooth regeneration control and his use of a 324 op amp as both an audio filter and a push-pull gives adequate, clean audio. Like other regenerative circuits, this one is sensitive to its surroundings and benefits from good shielding and layout after the board is working. The Far Circuits board worked the first time but care should be used to avoid control wires crossing each other as they leave it.
