Demod: SDR Receiver
Alphonse Romero
Getting the latest details from the App Store…
Demod turns your iPhone into a software-defined radio receiver. Connect to an SDR server on your own network or anywhere on the internet and explore the airwaves — from shortwave broadcasts and ham radio to aircraft, marine, and FM. Demod is a client for the most common SDR servers: • rtl_tcp — for RTL-SDR dongles • SpyServer — for Airspy and RTL-SDR • KiwiSDR — HF web receivers • OpenWebRX — web SDRs (HF, VHF and UHF) There's no hardware to plug into your phone.

Demod in the car, a smarter Seek, and a squelch that works everywhere: - CarPlay — listen to Demod on your car's screen. Pick a recent server or a saved station, see the band, station and country on the Now Playing screen, and use the steering-wheel buttons. Radio now plays across the car's music speakers instead of the voice speaker. - Seek — next/previous (in the app, in the car and on your headphones) now jumps to the next real signal for the mode you're in and stops there: the next AM station, the next SSB voice, the next CW signal. It stays inside the band you're tuned to and searches the whole receiver when you're between bands. - Siri and Shortcuts — "Tune Demod", "Play WWV in Demod" (any saved station), "Listen to (a favorite receiver) in Demod", or "Ask Demod what this signal is". - Identify, upgraded on iOS 27 — Demod reads the waterfall itself to help work out what an unknown signal is. - Squelch now works on KiwiSDR and OpenWebRX, and uses the same dB reading as the signal meter, so it's easy to set: put it just above the noise (thank you to our reviewer for the feedback!) - Band plans for your country, chosen automatically from the receiver's location and editable in the app (another great feedback item!) - More reliable listening on the move — Demod reconnects on its own after a dead zone and brings the audio back with it, and pauses for phone calls and Siri then picks up again. - FT8 no longer misses the start of transmissions on some receivers. - "Keep screen on while listening" option, and Recent Servers now list newest first.
