This is a simple, but elegant, QRP tranceiver for CW on 80m with about 0.25 Watt output. It is derived from the Pixie QRP rigs. Original info on this project is available at the KnightSMiTe Documentation Page. A condensed version in PDF format has been attached to this project. M0BLP has produced a modified PCB artwork which incorporates the J-FET substitution of D2 to give fixed TX with independent RIT. NOTE: Many units built by club members exhibited "motorboating" on receive when powered from a PP3 battery. To fix this put a large value electrolytic capacitor (typically 100uF, 16V) across the supply. Files related to the project : SMITETXT.pdf pixie2c5.bmp |
