Blue manual

Setting up and running a DENKO Blue lightning station — the DENKO Blue firmware for the Blitzortung System Blue controller (STM32).

Start here

Quick start — from a powered board to a working station on your network in about fifteen minutes.

Chapters

The Live page — the station's front page: traces from all four inputs, the survey, the spectrum views, the detector controls, and the language selector.
The Signal chain page — antenna to ADC as a live diagram: input paths, the two gain stages, the filter, and what is measured versus declared.
The GPS page — the sky plot, signal bars, timing lock, and how the station treats its satellite receiver.
The Tests page — the response sweep, the gain ladder check and the alias survey: the three hardware self-tests.
Firmware updates and stock conversion — automatic updates, USB (DFU) installation, and converting the board to stock Blitzortung firmware and back. Read this one before touching the Firmware page.
Settings and station identity — where each value comes from, every setting, and the local station number versus the Blitzortung-assigned one.
Lights, verdicts and messages — the indicator LEDs, the health verdict, registration notes, and network states.
The Diagnostics page and the JSON API — every reading the station publishes, and the machine-readable endpoints behind the pages.

This manual is in English for now; a Japanese translation is planned as a sibling tree, the way the Aurora manual's Japanese tree mirrors its English one. The station's own web interface already speaks twelve languages — see chapter 1.
