The Electroluminescent Receiver
Shown with the parts included in the kit with the optional LED Frequency Counter, Frequency Stabilizer (mounted in the bottom back) and S-Meter. Covers the CW portion of 40, 30, 20 and 17 Meters. Can be easily modified to cover the SSB section of 40, 20 and 17 Meters. Easy to follow pictorial instructions makes it a fun build.
Designed as a blood thirsty DX machine, it appeals to the young and the young at heart. With large boards and plenty of room, it is easy to insert parts, diagnosis, and make modifications.
The LEDs show circuit function - MOSFET (13 used) circuit health, gain of the amplifiers, oscillator drive, mixer gain, switching functons, and 12V power - it is the easiest superhet receiver to diagnosis and repair ever!
The ELR, which runs with the big boys, is finding a nitch with the little ones...and the YL's, too!

LED diagnosis, large circuit boards, wide traces/pads, and step-by-step pictures 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.
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.
