SDR Receiver vs MagicSDR

Demodulate and play AM and FM signals received by an RTL-SDR, Airspy HF+ or SDRplay radio. Requires a radio and a host computer which are not provided with SDR Receiver and must be separately installed and configured. Streams data from an rtl_tcp, hfp_tcp or rsp_tcp server application which are free and open source applications. The appropriate server application must be installed on the host computer and configured for the attached radio. SDR Receiver is a Software Defined Radio (SDR) that processes, demodulates and plays AM, narrowband FM and wideband FM signals. Listen to communications from aircraft (AM), amateur repeaters and VHF handhelds, police and fire, NOAA weather reports (narrowband FM) and commercial broadcasts (wideband FM). • Easily entered and managed lists of stations simplify station selection. • Export and import lists of stations in CSV or TSV format. • Adjustable squelch that works for both AM and FM signals. • Adjustable LNA gain (for RTL-SDR and SDRplay radios). • Adjustable audio high pass and low pass filters. • Audio AGC for AM, optimized for aircraft communications. • Selectable IQ Offset eliminates DC errors. • DC Blocker option reduces spurious errors. • Signal strength indicator that shows power level in the signal passband. • Multiple sampling rates to accommodate different network bandwidths. • Selectable 8-bit or 16-bit sample size streaming from Airspy HF+ and SDRplay radios. • Option to play audio over AirPlay to a HomePod, HomePod mini or any AirPlay compatible device. • Stream synchronized audio to multiple AirPlay 2 compatible devices. • Lock Screen shows controls and streaming station information. • Custom URLs enable another application on the same device to set the station and start streaming. • Supports VoiceOver. SDR Receiver processes signals that are streamed over the network from a host computer (Mac, PC or Raspberry Pi) that is attached by USB bus to an RTL-SDR, Airspy HF+ or SDRplay radio. An rtl_tcp server or equivalent application running on the host computer receives baseband IQ data from the radio and streams the sampled signals over the network to the iPhone or iPad running SDR Receiver. Requires an RTL-SDR, Airspy HF+ or SDRplay radio and a host computer which are not provided with the application. Support for 192 ksps and 384 ksps Airspy HF+ sampling rates requires Airspy HF+ firmware version R3.0.7 or later, and hfp_tcp version v.1.2.117 or later.

Turn your iPhone or iPad into a real radio receiver. MagicSDR connects you to more than 600 live SDR (software defined radio) servers around the world — tune in to shortwave broadcasts, ham radio and utility stations right away. No antenna, no dongle, no hardware required. WHAT YOU CAN HEAR - International shortwave broadcasters from every continent - Ham radio operators on SSB and CW — contests, DXpeditions, everyday QSOs - Aviation, marine and utility stations - Time signals, beacons and digital modes Pick a receiver close to the signal you want: a server in Japan, Brazil or the Alps is one tap away. Somewhere the bands are always open. HAVE YOUR OWN SDR HARDWARE? MagicSDR also works as a fast native client for your own receivers. The app supports the SoapyRemote protocol, which means it works with any SDR device that has a SoapySDR driver. More supported protocols: - rtl_tcp — stream IQ data from the popular and affordable RTL-SDR dongles - Airspy network — connect to Airspy receivers shared over the network - Hermes-Lite — direct connection to the open-source Hermes-Lite 2 HF transceiver A POWERFUL RECEIVER WITH A TOUCH-FIRST UI - Wideband panadapter and waterfall with smooth pinch-to-zoom and pan gestures - AM, SSB (USB/LSB), CW, NFM and WFM demodulators - Adjustable filter bandwidth and noise-threshold squelch - Frequency bookmarks to collect and organize stations - Band plan overlay, so you always know where you are on the dial - Audio over UDP — feed external decoders such as FT8/WSJT-X or CW - Built-in EiBi shortwave schedule database — instantly see which broadcast station is on the air, in what language and when MADE FOR Ham radio operators, shortwave listeners (SWL), DXers, spectrum analysis — and anyone curious about what is on the air right now. Feedback and feature requests are always welcome — MagicSDR is in active development.
