"The Electroluminescent Receiver Kit"

Electroluminescent Diode: a p-n junction device which takes electrical current
and voltage and changes it directly to light. (QST, July 1974, page 62.)

The most beautiful Electroluminescent Receiver to date. Built by Chuck Nolin, WA6LTV/4, based on the same design techniques as the last receiver seen here. Some really beautiful craftsmanship here. The edges of the case are fired with Super Bright Blue LEDs. This receiver uses the new LED Frequency Counter. More pictures here.

To see past front cover pictures, go to "Front Cover Pictures".

LED diagnosis, large circuit boards, wide traces/pads, and step-by-step instructions make this the easiest double conversion receiver you will ever put together. For more information read

Amateur Radio Receiver

An CW/SSB receiver that covers the first 100-150 kHz of the 40 and 20 meter bands and all of the 30 and 17 meter bands. Bandwidths can be modified.

SWL Listeners

The tuning range of the VFO is expanded to 500kHz to cover most of the 41/31/19/16 Meter SWL bands. Duncan Watson and Gary Rondeau have sent in modifications they made for improved performance of their receivers. They include VFO, crystal filter, AM Detection, and AGC modifications and improvements - check them out.

New LED Frequency Counter!

For Beginners and 50/60's Heathkit builders who want to try building the Electroluminescent Kit


KC5WA's ELR

KC5WA is currently building the ELR and is documenting his construction with pictures and comments. Check out the following link for some real time building information: http://www.kc5wa.net/ELR/elr.html


Ray Babbitt's ELR

Ray Babbitt has built an amazing ELR with extensive mods. Take a look at it here (about halfway down the page). While there, look at some of his other cool projects.

Take a look at some of the pics he sent me. Check them out here.

A QRP Transmitter Design for transceive operation using Superhet Receiver VFOs.

Incorporating this design with the Electroluminescent Receiver Kit.
This is for dead-bug or perforated board
builders only. A PCB kit will eventually be
available after more testing has been done.

Transceiver Operation with the ELR

An updated version of the article "The Best QRP Amp in the World - The DL-QRP-PA" recently published in the Flying Pigs BBQ Newsletter, January 2010

Beginner and Experimenter's
Receiver Kit

Has been used for college and university
term papers and projects in England and
the US. Easy for the beginner to build
and modify.

Super Receiver

Based on circuits using the 2N5109 transistor.
I have been careful to propose a receiver that
is "buildable" by anyone with moderate
experience in homebrewing. Done all "dead bug" style.

LED Mosfet Receiver

Home page has several great links to LED sites.
These pages contain the history of the MOSFET
receiver, going back into the 70's.
