This week, we’re looking at some practical builds and technical deep dives that should resonate with anyone pushing the boundaries of their station. We’ve got a clever approach to a portable 6-meter beam, something that comes up often for summer field operations, alongside a detailed examination of feed line impedance matching using common coax. For those experimenting with RF, there’s a useful wideband noise source for filter alignment, particularly handy for homebrew projects or transceiver maintenance. We also cover a robust 4:1 Guanella current balun construction, essential for many antenna configurations, and a neat utility to bridge your local transceiver with a remote KiwiSDR. Finally, a compact QRP CW transceiver build rounds out the selection, perfect for the minimalist operator or a quick weekend project.
