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.
A classic circuit and a favorite in the QRP community. A QRP SSB/CW Transceiver for 14MHz -- Part 1. QST December 1989, pp. 18-21. Exotic circuitry and hard to find components aren't necessary if you want to build excellent performance into a home-brew SSB/CW transceiver: Careful design is the key.
Improved supply decoupling (C1, C2, C10, C11). A beefed-up output transistor with heat sink (Q2). A BFY50 is a robust replacement, but better still is one of the Club’s 2N3866 equivalents which also gives slightly better receive sensitivity and about 500mW RF output at 13V.
