This book aims to collect and share knowledge related to the art of QRP. There are many schemes and projects available on the web, but after some time some schemes disappear if the sites are no longer maintained.
The easiest QRP is just a crystal-controlled oscillator. It usually has one to three amplifier stages to raise the power to between 1/2 to 5 watts. This will get you on the air quickly. Unfortunately crystal control means you must order $18 custom crystals for your favorite frequencies in each band.
Student Manual. Revision V 1-0. Introduction. The Pixie 2 is a small, versatile radio transceiver that is very popular with QRP (low power) amateur radio operators the world over. It reflects a history of contributions from amateur radio operators looking to build the simplest transceiver possible.
This page has been set up so that more detail of the schematics can be seen than might be available in the printed article and also includes two parts lists. One list is set up so that all of the parts for a specific buidling block complete with the part numbers and the identified supplier.
