Bitx20 V3 "Dead Bug Style" RF amplifier section

After a few hours of work I completed the RF Amplifier section.Be carefull that transistor Q1 is a 2SC2570A in stead of a 2N3904.If you cannot purchase a 2SC2570A,you can use the more common MPSH10.No special cores have to be wound in this stage of the build.Next is the bandpass filter.I`m thinking of using the same as the one discribed on the PI4RAZ forum.
