A recent transceiver by Roger G3XBM has got quite a few people interested. His design is for an HF transceiver using just a single transistor (14 components in total). Of course there are certain compromises to the design (like 15mW output) and a slightly insensitive receiver but the design does work. G3XIZ built one for 80m and has had quite a number of contacts with it. To date he has had 16 contacts and 51 reports from across Europe. It might be fun to try one for SOTA so I may build something similar myself. Anyone else fancy trying?
The design is online at:
Maybe there should be a Single Transistor on the Air award?
