Shortwave SDR Radio: GlobalSDR

Hear the world's radio, live, from your iPhone.

GlobalSDR connects you to more than 1,300 real radio receivers run by volunteers on every continent. Tune a shortwave broadcast from Asia, listen to oceanic aviation weather, catch a ham radio contact or find a numbers station. No radio, no antenna, no hardware to buy.

Know what you're hearing

GlobalSDR reads the clock as well as the dial. Tune any shortwave frequency and it shows which station is scheduled right now, from which country, in which language and for how much longer. Browse everything on air worldwide in your language, see what starts in the next hour, and get a reminder before a broadcast begins. The schedule works offline.

See the spectrum

A native, hardware-accelerated spectrum and waterfall, drawn the way radio operators know it. Drag to tune, pinch to zoom, adjust the passband with your finger, and see station names right on the waterfall. Choose AM, SAM, LSB, USB, CW or NFM, set AGC, filter width and waterfall speed.

Know which bands are open

A band conditions dashboard built from live NOAA space-weather data: K index, solar flux, sunspots, X-ray flares, band-by-band day and night outlooks and the time of your next greyline. The receiver map shows the day and night terminator.

The right receiver, picked for you

Type a frequency and GlobalSDR connects to a free receiver that covers it. If a receiver is full or offline, it suggests the next best one. Browse the list or the map, filter by network, free slots or coverage, and save favorites.

Listen anywhere

Background audio with lock-screen controls, Live Activities and the Dynamic Island. Widgets for now listening, band conditions and one-tap channels. Control Center controls. Siri and Shortcuts. An Apple Watch remote with Digital Crown tuning. Sleep timer included.

Scan

Built-in scan groups for time signals, aviation, military and utility, numbers stations, amateur digital modes and marine, or build your own with signal hold and an audible cue before each step.

Built on respect

Every receiver is run by a volunteer paying for their own hardware and bandwidth. GlobalSDR identifies itself honestly, opens one connection at a time and releases its slot the moment you stop. Receiver rules and donation links are one tap away. With thanks to the KiwiSDR, OpenWebRX and WebSDR communities, EIBI and NOAA SWPC.
