7.040 MHz, the International QRP frequency • Excellent and clean keying waveform • Built-in antenna T-R switch • Operates on 12 - 15 volts DC at 1/4 amp current • Appoximately 1 Watt RF power • Clear, concise step-by-step instructions carefully guide you to a finished kit that not only works - but you’ll also learn too!
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.
15 cze 1998 · An exclusive collection of QRP circuits. Do it your self, come and get simple circuits that you can build to enjoy real hamming. Simple Receivers, Transmitters, Transceivers, Antennas and many more.
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.
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.
