Scroll, pinch, or hit + to zoom in — the spectrum goes 20 layers deep

Educational—not an operational spectrum-management or EMCON tool.

Welcome

The whole electromagnetic spectrum, on one zoomable strip.

Start wide—radio through gamma—then dig as deep as you like: band nomenclatures (ITU, IEEE, NATO), US frequency allocations, and the actual radars, satellites, phones, and gadgets that live in every slice.

Scroll to zoom, drag to pan the strip.
Click any block to see what it is, who uses it, and where the official rules live.
Shift-drag to draw your own range and see everything inside it.
Open “What do you want to see?” to add MILSATCOM, EW, ham radio, medical, and more.

About this project

Hey—we’re Sean and Derek. This is EM Spectrum Explorer.

The electromagnetic spectrum is where modern naval operations are won and lost—communications, radar, navigation, electronic warfare—and it is usually taught as a wall of tables. This site turns those tables into one zoomable picture: browse from the seven classic regions all the way down to a single allocation block, switch between the nomenclatures different communities use, and see exactly which systems—military and civilian—occupy every slice.

This site is intended for learning, not operations — do not use it for operational decisions; use it at your own risk.
