What does HAMIOS do?

HAMIOS combines dozens of data sources into one dark, customisable dashboard. Whether you want to chase DX, track a solar storm or just know which band is open right now — everything is right in front of you.

One dashboard for everything

HF radio propagation depends on the state of the ionosphere — a layer of the atmosphere ionised by solar radiation. Solar flares, geomagnetic storms, and the day/night cycle all influence which frequencies travel where, and how far. To get a complete picture, an operator traditionally had to visit a dozen different websites: one for solar indices, another for Kp forecasts, a third for live DX spots, yet another for lightning conditions. HAMIOS brings all of that together in a single, always-on window.

The application pulls live data from authoritative sources — NOAA SWPC for solar and geomagnetic data, DXWatch.com for DX cluster spots, Blitzortung.org for real-time lightning positions, and SatNOGS DB and AMSAT for satellite TLE orbital elements. It processes and correlates these streams continuously, then presents everything through a set of colour-coded panels arranged around a high-resolution world map.

How it works

At the heart of HAMIOS is a band reliability engine. Using the current Solar Flux Index (SFI), Sunspot Number (SSN), Kp index, and time of day, it calculates a reliability percentage for each amateur band from 160 metres down to 6 metres — separately for day and night paths. The results are shown as colour-coded bars (red → yellow → green) so you can see at a glance which bands are worth trying.

The 4096 × 2048 world map draws the day/night terminator in real time, overlays the aurora oval derived from the current Kp index, and plots live lightning strikes as they are detected by the Blitzortung sensor network. Satellite positions and ground footprints are computed from fresh TLE data and updated every few seconds. DX cluster spots appear as labelled markers on the map, making it immediately obvious where activity is concentrated.

If your radio supports CAT control (Yaesu, Kenwood/Elecraft or Icom), HAMIOS can connect via the serial port and tune directly to a clicked DX spot — no manual frequency entry needed. An automatic alert system watches for approaching thunderstorms and deteriorating geomagnetic conditions, and posts timestamped warnings in the notifications panel the moment a threshold is crossed.

Who is HAMIOS for?

🎯
DX hunters

Live DX spots, band reliability scores and a world map with active regions pinpointed — everything needed to decide in seconds whether a rare entity is workable from your QTH.

🔬
Solar observers

90-day interactive charts for SFI, SSN, Kp and Bz, plus GOES X-ray flux graphs, let you study solar cycles and their effect on the bands over time.

Propagation overview is back

  • The card-style advice panel from before v5.7 returns as Propagation overview, next to Propagation Advice: eleven fixed cards, band percentages from the calibrated model

v5.8.2 28 September 2026

Faster map, clearer HF absorption

  • Much lower CPU use: idle from ~16 % to ~4 % of one core — lightning dots are cached and only the areas around the growing strike rings are redrawn
  • HF absorption (NOAA D-RAP): a status line on the map shows the data time and the peak absorption, so an empty layer on a quiet sun no longer looks broken

About HAMIOS

HAMIOS (HF Atmosphere Monitor for Ionosphere Observation and Statistics) was developed by Frank van Dijke , a radio amateur from the Netherlands. The project started as a personal tool to quickly assess band conditions without having to consult dozens of websites.

The software is fully open source and actively maintained. Contributions, bug reports and suggestions are welcome via GitHub.

Developed in collaboration with Claude AI (Anthropic) as coding assistant.

Why are Spy Stations, EIBI and FT8/Digi frequency lists included in this program?

A fair question, with a very simple answer: because it can.

During the development of Hamios, the need — and challenge — arose to connect Hamios to my transceiver, a Yaesu FT-950. Since I own a U5 Link interface, it had to be possible to make both communicate with each other. After feeding Claude with the FT-950 CAT manual, development progressed surprisingly fast… and so did my imagination. What could I do with these new possibilities?

The first step was importing the EIBI list into Hamios, simply to see if I could control the radio directly from the list. To my surprise, it worked immediately. The EIBI list contains a huge collection of interesting frequencies, and I quickly started to see a clear connection between Hamios and this source of information.

Spy stations have always captured my imagination — and probably that of many others as well. So it was only a small step to integrate those lists into Hamios too. And since convenience matters, the FT8 and Digi frequency lists eventually followed as well.

At the moment, Hamios does not yet do much with those FT8/Digi lists, but they are definitely high on my wishlist for future development.

So if you ever wondered why all those lists are included in Hamios, this is the answer:

Because it can.
