About AM_SW Radio

AM_SW Radio connects any of hundreds of receivers across the globe and streams the audio of the radio signals to your iPhone. The use of ad-hoc 'KiwiSDR' servers provided by volunteers allow you to experience radio reception from 100kHz to 30Mhz using AM or SSB modes as if you were located where the server is.

What’s new

Version 1.4 · Updated June 17, 2026

Improved AM Broadcast band reception with new AM-Wide and AM-Extra-Wide modes. If connected to a Kiwi server that supports extra-wide '20khz bandwidth' mode the new AW and AWU mode can supply up to 9khz audio bandwidth, otherwise you hear the maximum audio bandwidth the server supplies (normally 6khz). AWU mode adds the NRSC equalization curve used by US based AM BCB stations (AW without equalization is for international BCB reception). International users can select to use 9khz frequency Jogging within the BCB. A 'Master Audio Gain' is provided for users that wish to adjust for certain server configurations. Enhanced connectivity compatibility with certain Kiwi servers operating behind strict router configurations.
