The µSDX is a simple but very efficient QRP Multimode Shortwave Transceiver, that is able to transmit and receive SSB, CW, AM and FM. It can be configured for any Shortwave Band by exchanging/modifying RF PCB.
Chapter 6. BUILDING A HOMEBREW QRP. Among the guys I work, QRPs seem to be the most common homebrew project, second only to building antennas. Therefore this chapter describes a simple QRP design I have settled on. I use my QRPs as stand-alone transmitters or I use them to drive a final amplifier to produce higher power, 25 to 100 watts.

controlled (single frequency) sub 1-Watt QRP CW transceiver. One of the most impressive features of the Pixie 2 besides its simplicity, are the modification possibilities such as operating at a wide range of RF frequencies. In this guide, the version we will be building is the S-Pixie as designed by Jason BG2XNN of LXQQFY.com in China.
Figure 1 — Detailed schematic diagram and parts list for the RF portion of the Universal QRP transmitter. Resistors are 1 ⁄ 4 W, 5%. A kit of component parts is available from Kanga US. 7 C10 is a VXO capacitor placed in series with the crystal to provide some frequency adjustment around the crystal frequency.
