2-10 MHz Shortwave receiver and 1 transistor VFO's

2-10 MHz Shortwave receiver and 1 transistor VFO's

ByKo Tilman

Text: English. A book in which a schematic for a simple 5 transistor radio (excluded the audio amplifier) for Shortwave is published. Also a few VFO's are published to make this radio operational on Shortwave. Please make the following corrections/adaptations to the text: a) page 17: the VFO signal is injected in the emitter from TS 2 b) page 25: the sentence "like the 2N2219" must be removed c) page 27: "medium power NPN transistor must be "medium power PNP transistor". On page 68 and 69: the BC 557 is a PNP (!) transistor, the arrow at the emitter is drawn in the wrong position (sorry, situation 10okt2015). All schematics are correct.Copyrighted content.
