1.3
August 5, 2026
• KiwiSDR support — connect to KiwiSDR HF web receivers, with live audio and waterfall streamed straight from the server. Great for shortwave and the ham HF bands when you don't have your own antenna up. • Browse public receivers worldwide — now on a station map as well as a list • Time-Shift — pause and rewind live radio (about 3 minutes of DVR buffer) • Record what you hear, with a pre-roll of the moment you tapped Record • Live Text — on-device transcription of the audio, with on-device translation of the captions (iOS 18+) and a full-screen transcript reader • Identify — tap the new button on the waterfall to ask "what is this signal?" • Scanner — scan memories, a band range, or let Smart scan find active signals • Noise reduction (spectral DNR), noise blanker, and mains-hum notch • Decoders (beta) for CW, RTTY, PSK31, and FT8 — FT8 uses a much more sensitive decoder that pulls far more signals out of a busy band • Redesigned controls: five focused tabs instead of one long list • Audio now resumes automatically after phone calls and Siri • Many robustness and stability fixes throughout
