Описание

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.

• 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.

• Reduces audio output latency.

1.1.2

2019-08-23

Updates and layout improvements to support iOS 13.

1.1.1

2019-04-05

Adds support for SDRplay radios and for 16-bit samples.

New:

• Sample Size option in Settings - Sampling enables 16-bit samples for Airspy HF+ and SDRplay radios.
• SDRplay option in Settings - Server Type enables all available sample rates and 16-bit samples.

1.1.0

2018-12-05

New:

• Highlights a selected entry on the Stations tab with a light blue background.
• The Preset section of the Lists tab can now be collapsed by tapping the Preset section header, and it can then be expanded by tapping again.
• Adds a Port option on the Settings tab where a Port number can be entered. The default Port is 1234.
• Adds a Tuning option on the Settings tab for selecting a tuning step size. The set of possible step sizes and the saved step size are specific to each modulation type.
• Adds a Support option on the Settings tab. An email requesting support can now be composed and sent directly from within the app.
• Adds a Twitter option on the Settings tab which displays the @SDRReceiver Twitter page.

Improved:

• Expanded Help documentation with: instructions for installing rtl_tcp on Windows; steps for building and installing hfp_tcp for Airspy HF+ on Raspberry Pi and macOS; procedure for building the Airspy HF+ Library on macOS.
• Reduces latency when changing sampling rate and when changing audio filter frequencies. An audio filter frequency change takes effect immediately when a new frequency is selected.
• Calculates the signal strength estimate (which is displayed on the signal strength bar and used by the energy squelch) so that it is independent of the LNA Gain setting. As a result, a change in the LNA Gain setting will no longer change the AM squelch threshold or the displayed signal strength.
• Saves the highlighted station on the Stations tab and the state of the Preset lists (collapsed or expanded). These states are restored when the app is restarted.
• Saves the Volume control, AGC/Man control and LNA Gain values. These values are restored when the app is restarted.
• A long press on the frequency up/down buttons will now change the frequency repeatedly by the selected tuning step size.
• When the tuning step size is set to Default, the default value is shown on the right side of the segmented control.
• Audio filter frequency choices and saved values are now associated with a particular modulation type. When Default is selected, the default value will be displayed on the right side of the segmented control.
• Sets the signal strength bar to the minimum value when streaming is switched to Off.
• Checks Host and Port entry fields for validity as characters are entered. The Save option is enabled only when the entry is valid.
• Improves the layout of section headers so that they have the same appearance and text style on all three tabs and take up significantly less vertical space on the Settings tab.
• Ends Edit mode on the Stations tab when a new list is loaded.

Fixed:

• Fixes a bug in the FM demodulator that resulted in the audio amplitude being larger at lower sampling rates.
• Fixes a bug that could allow the demodulator to continue running after a connection failed. Signal processing now stops when a connection stops running.
• Fixes a bug that caused a crash when an NFM station was streaming and the 14.250 kHz audio low pass filter value was selected. The 14.250 kHz filter frequency is no longer an option for NFM.
• Fixes a bug in the display of an Update popover on the Lists tab on an iPad. The popover is now anchored to the + button.
