QuestaSDR Android App now with Remote Network Streaming: RTL-SDR, Airspy, SDRplay Supported

Back in April we posted about QuestaSDR, which had just released the Android version of its SDR software. Recently QuestaSDR programmer 'hOne' wrote in and noted that a new update has enabled remote streaming in QuestaSDR.

To get set up, just run the Windows version of QuestaSDR on a PC, and open the "SDR Server" app. Once the server is running, you can connect to it via the Android version of QuestaSDR over a network connection. The server supports the RTL-SDR, Airspy and any ExtIO compatible device such as SDRplay units. As far as we're aware, this is the only Android app that currently supports streaming from non rtl_tcp compatible units such as the Airspy and SDRplay.

hOne has been able to run an Airspy at the maximum bandwidth of 10 MSPS through his network connection. He also notes that you can now zoom into the IF spectrum in detail by using the new "IF Spectrum" plugin.

hOne also notes that the streaming feature is currently in beta, and any bugs/suggestions or feedback are welcome.

QuestaSDR: New RTL-SDR Software for Android

Last year we posted about QuestaSDR, which is a simple SDR multi-mode GUI that is compatible with the RTL-SDR. Since then QuestaSDR has evolved, and is now available on Android devices as well. It looks to be a nice alternative to RF Analyzer and SDR Touch which are the most popular RTL-SDR Android apps. The description of Android QuestaSDR reads:

QuestaSDR - powerful and flexible, cross-platform Software Defined Radio Application (SDR). Built-in scheduler architecture provides integrate plugins, plugins kits and multi - UI. Typical applications are DXing, Ham Radio, Radio Astronomy and Spectrum analysis.

Support Hardware:
- RTLSDR Dongle

Main features:
- Dark, Ligth, Universal, Material application style
- Many spectrum settings (FFT size, waterfall FPS and color theme)
- AM/SSB/NFM/WFM demodulator
- RDS decoder
- Record AF file
- Frequency bookmarks
- Web remote
- Supported IF-adapter, upconverter, downconverter hardware
- Rig samplerate, frequency, level and iq disbalance calibrate

To start using QuestaSDR, you will need:
- RTL-SDR dongle
- USB OTG Cable - used to connect a RTLSDR to your Android device.

Connect the USB dongle to the USB-OTG, then insert the free end of the cable into the USB port of your Android device and launch the QuestaSDR! Now you can listen to live frequency range shortwave, VHF, UHF.

Feedback and bug reports are always welcome.

QuestaSDR (Formerly UnoSDR) Updated: Now Supports Airspy and many new Features

Back in March Vi Vitaliy wrote in to let us know about an RTL-SDR compatible SDR program called UnoSDR that he had been working on. Vi now writes that the software has been updated, and the name has been changed to QuestaSDR to avoid confusion with SDRUno – SDRplays official software package. Vi writes:

In new version I added support AirSpy r2, AirSpy mini, Perfomance Window, Record AF, record and play iq raw data, frequency bookmarks, waterfall color scheme, change fft size, fps … calibrate options, support if converter.

The software is still in beta, and Vi would be interested in hearing any feedback or bug reports if you have any.

QuestaSDR can be downloaded from sdr-labs.com.
