A research group's newsletter announcement from a new website that is still under construction, with the excerpts mostly containing placeholder or unclear text. Readers get little beyond a notice that content will appear soon and an invitation to subscribe.
Website: https://www.sipg.tecnico.ulisboa.pt/
Technical articles on RF and analog electronics, covering topics like transistor impedance matching, PCB dielectric constant measurement and digital filter design. Each issue works through the theory with equations, figures and hands-on measurements.
A personal blog-style newsletter from an engineer at the Allen Telescope Array covering GPU-accelerated signal processing, software-defined radio tooling, and SETI observatory life. Readers get technical explanations of the author's open-source projects plus photo posts from the observatory and Berkeley.
Release notices and changelogs for Radwave, a desktop audio and signal-processing app with an engine for Breakthrough Listen radio data. Issues mostly list version changes, with occasional detailed write-ups of technical fixes such as download throttling and GUPPI header time-tracking bugs.
