A recent SolderSmoke Daily News post spotlights a compact 40-meter homebrew receiver by Hidehiko, JA9MAT. The build is a reminder that hands-on receiver work remains a living part of amateur radio: a practical project can combine older operating ideas with current components, fabrication methods, and a lot of individual problem-solving.
The receiver shown uses a PTO with a long tuning shaft, a wooden base, and several 3D-printed coil forms. The builder describes an SA612 detector alongside a two-transistor Franklin VFO, details that will be familiar to experimenters and may give newer builders a few terms to explore.
This is not a kit review or a build guide, but it is an encouraging example of the kind of homebrew work that clubs can share at meetings, on nets, or during a bench-building afternoon. The original post includes the demonstration video and the builder’s notes.
