K3PGP’s Experimenter’s Corner looks like what happens when a workbench gets enough disk space to become a website.

The site’s own slogan is “From VLF to Light,” and it earns the phrase. Its sections wander through astronomy, bicycle-mounted cameras, construction projects, lasers, moonbounce, software, radio experiments, test equipment, repair notes, and assorted technical material accumulated over years.
The pages identify the material as copyright 1995–2020 and warn that some of it may no longer be current. That warning is useful rather than embarrassing. The value of the archive is partly that it preserves how an experimenter actually worked through technologies that changed underneath him.

The software section alone is a small museum of weak-signal computing. It includes material for PSK31, moon tracking, DSP experiments, helical-filter design, sound-over-IP, and visual radio modes. One PSK31 page targets Windows 3.1, Windows 95, Windows 98, and Windows NT with SoundBlaster-compatible audio hardware.
That operating-system list dates the problem better than any redesign could.
Elsewhere the site crosses from radio into optics. Laser pages document experiments involving laser moonbounce, cloud bounce, laser radar, and an AO-40 laser experiment. Other sections preserve VLF work, telescope and eclipse material, old test-equipment repair, and even snapshots of projects such as SETI@home.
What ties it together is not a subject category. It is the experimenter’s habit of documenting the thing that was on the bench that week.
Modern technical publishing tends to split those interests into separate channels: amateur radio here, astronomy there, optics somewhere else, software on a code host. K3PGP leaves the connections visible. A receiver problem can lead into DSP. Astronomy can lead into moonbounce. A laser can become another communications path.
CacheRat’s 1,967 Ancient Web Domains research list includes technical personal sites like this because the useful part is often the accumulated cross-talk between hobbies.
K3PGP is not a polished course.
It is better understood as a long-running notebook with solder on the margins.
