After a few hours of soldering ,I almost completed the 7th and 8th stage of my Bitx20 V3 "dead bug" style 20 meters QRP Transceiver project.Transformers T1 and T1a are the same as in the BFO.13 trifilaire windings thrue the ferrite core.For the diode bridge I used a piece of double side PCB.Just one more transformer has to be wound,but I will do that the next time.After that I have to test the whole circuit.
