Note: Since the introduction of solid-state devices many ARRL transmitters have been QRP. Refer to the "ARRL Handbook", the "QRP Notebook" and the "First Steps in Radio" publications for additional circuits. We also have a bibliography of HF transmitters that has a lot of QRP circuits. Other amateur publications also contain many low power circuits that will be of interest to the QRP'er. 1980 August QST p. 14 An Optomized QRP Transceiver 1981 April QST p. 35 A QRP Transmitting Converter 1985 January QST p. 22 Simple QRP Gear Versus Good Performance 5 pages October QST p. 14 Better Ears for the MAVTI-40 Transcvr. 7 pages 1986 February QST p. 23 Four Watts, QSK, for 24.9 MHz 4 pages July QST p. 34 The SWR Twins - QRP and QRO 4 pages August QST p. 30 The QRP Transmatch - A Novel Approach 4 pages December QST p. 19 Three Fine Mice - MOuSeFET CW 6 pages Transmitters 1987 July QST p. 30 Low-Cost QRP Power Boosters 4 pages November QST p. 18 Build This QRP Omni Box 5 pages 1988 QST p. 30 Some QRP Transmitter Design Tips 3 pages 1989 October QST p. 25 The QRP 3-Bander (transmitter) 1990 January QST p. 28 A QRP SSB/CW Transceiver for 14 MHz.
