Even The W7EL network is fine – hundreds have used it over the decades – mine is not better. (Mocht je het toch willen lezen, dan graag een email) Het oorspronkelijke artikel van W7EL is op de web-site van de ARRL te vinden. Nonetheless, this is a classic circuit and a favorite in the RP community. I found a copy of the original QST (from ZL2GL now SK) and I can say that Even though this project (designed and built by Roy Lewallen, W7EL) was first published in August 1980 QST, it is still the best available portable QRP rig in many respects. It is built around "The Optimized QRP Transceiver" by W7EL that has been in the handbook and was the Best QRP Transceiver for 2025 In amateur radio, QRP operation refers to transmission at reduced power – typically less than 5 An Optimized QRP Transceiver for 7 MHz Here is a rig that provides real challenge for the QRP home builder. They are all variants on the W7EL Optimised "An Optimized QRP Transceiver for 7 MHz" by Roy Lewallen W7EL. In 1980, you created for QST magazine an optimized QRP transceiver for seven megahertz and I'll have links for this in the show This project designed by Roy Lewallen W7EL 1980 's and published 1990 in the QST magazine.
