Shortwave SDR Radio: GlobalSDR

About

Hear the world's radio, live, from your iPhone. Tunar 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 Tunar 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 Tunar connects to a free receiver that covers it.
