SDRuno: SDRplay introduces a free native app for the RSP

(Source: SDRplay Press Release)

SDRplay is pleased to announce the official release of SDRuno for the RSP. SDRuno is the new name for the RSP compatible version of Studio1, the rights to which we obtained and announced on 28th April. SDRuno contains native support for the SDRplay RSP and no extra plugins are required. Third party hardware can also be supported via the ExtIO interface, but with reduced functionality.

SDRuno provides a rugged and flexible, high performance SDR receiver capability and boasts some excellent features:

Multiple ‘Virtual Receivers’ which allow for simultaneous reception and demodulation of different types of signals within the same receiver bandwidth.
A selectivity filter with an ultimate rejection greater than 140 dB.
A unique distortion-free double stage AGC with fully adjustable parameters.
Multiple notch filters with BW adjustable down to 1 Hz, Notch Lock feature.
A unique synchronous AM mode with selectable/adjustable sidebands, dedicated PLL input filter, and selectable PLL time constants.
SNR (stereo noise reduction), featuring a proprietary noise reduction algorithm for stereo broadcast.
AFC for FM signals.
Calibration for receiver frequency errors.

Over time, we plan to add many more features to SDRuno to enhance the user’s experience of this very powerful piece of software. This software runs on Windows and we don’t yet know how easy it will be to migrate it to other platforms but this is something we will be investigating.

SDRuno will be made freely available to all current and future users of the RSP – to download a copy – simply go to http://www.sdrplay.com/windows.html

Our support for SDRuno in no way lessens our commitment to support HDSDR, SDR Console, Cubic SDR or ANY other software solution where the authors are willing to work with us. We fully recognise that many people have strong preferences for particular pieces of software and we do not want to do anything to undermine the options that people have to use their favoured software packages. Indeed, our view is quite the opposite. Our objective remains aim to have our hardware platforms support any and every SDR package out there. This of course may not be possible, but it is our philosophy and part of the ethos of our company.

About Studio 1:

Studio1 was developed in Italy by SDR Applications S.a.s. and has hundreds of happy customers around the world. Studio 1 is known for its user friendly stylish GUI, CPU efficiency and advanced DSP capabilities, including features not available on other SDR software packages.

Beta release of SDRplay ADS-B for Windows

SDRplay: Updated ADS-B for Raspberry Pi 2 and Pi3

3 Replies

Image Source: FAA.gov

Many thanks to Jon Hudson with SDRplay who shares the following announcement:

We now have an updated beta version of ADS-B for both the Raspberry Pi 2 and 3. This is based upon the 16bit Mutability version of dump1090 developed by Oliver Jowett and unlocks the full 12 bit performance of the RSP1. People should see a significant performance improvement over the dump1090_sdrplus version, which was based upon 8 bit code. The latest beta version can be downloaded in binary form from http://www.sdrplay.com/rpi_adsb.html .

Should anyone have questions or feedback, please contact [email protected]

Section 1 is how to load a brand new image onto an SD card

Section 2 should be straightforward – 2 commands – one to get the software and another one to run it.

Though I don’t live in a metro area with a lot of air traffic, I am often in the flight path of a couple major airports. I’ve been looking for a simple way to try ADS-B (and ACARS). As soon as I locate a dedicated monitor and keyboard for my Raspberry Pi 3–and a little dedicated time–I will give the ADS-B app a go. Thanks again, Jon!

The SDRplay RSP software defined radio

Many thanks to Jon Hudson at SDRplay who shares the following news:

The latest EXTIO control file (Version 3.8.1) has a very cool new feature for shortwave listeners interested in hunting HF DX stations.

Using the world-wide station list mintained by http://www.eibispace.de/ you can see the name of stations appear in a pop-up window as you select a particular broadcast signal. The details are in the updated EXTIO user guide selectable from the Platforms section or by clicking here.

There’s a video demo here:

SDRplay shipping the RSP in quantities of 1,000 a month

2 Replies

SDPlay-RSP This article from Electronics Weekly just popped up in my news feed:

SDRplay of Wakefield, the 18-month-old software defined radio specialist, is now shipping its $149 software defined radio (SDR) receiver in quantities of 1,000 a month

Inspired by the SDR capabilities that even a simple 8-bit TV dongle can perform, SDRplay had the idea of partnering with Mirics to take their 12-bit wideband broadcast chipset and to re-purpose it for the hobbyist market.

At the moment, the hobbyist market for SDR radios tends to be dominated by radio amateurs and ‘short-wave listeners’ and SDRplay’s initial product, the ‘Radio Spectrum Processor’ (RSP) has been well received – winning Ham Radio Science’s RSP ‘Best Bang for the Buck’ rating.

Continue reading at Electronics Weely’s website…

I’m quite proud of the folks at SDRplay as their RSP is truly one of the best receiver values on the market right now.

After (apprehensively) agreeing to review the SDRplay RSP last year, I was simply blown away by this little $149 receiver’s performance. Click here to read the review. Later, I couldn’t bring myself to return the RSP on loan for the review–so I purchased it instead.

I’m glad I bit the bullet!

In fact, last year, at the SWLing Post DXpedition, my buddy, Mark Fahey–who traveled all the way from Australia–forgot to bring the appropriate power adapter for his WinRadio Excalibur, so I let him use mine. I had planned to run the WinRadio Excalibur and Elad FDM-S2 simultaneously on my PC so that I could record spectrum in two different parts of the band at the same time.

Fortunately, I brought the SDRplay RSP, so it took the Excalibur’s place and ran alongside the FDM-S2. It worked amazingly well!

(I should note here that I also believe the FDM-S2 is a great value–at $519 US, it holds its own against receivers that cost upwards of $1,000.)

Shortly after I published my RSP review, I invited SDRplay to become a sponsor of the SWLing Post. I’m happy they accepted. Sponsorship on the SWLing Post is only open to retailers and manufacturers who produce quality goods; those who are well-known in the industry and, often, ones with which I have direct experience. I think SDRplay is a great fit.

So, Kudos to Jon Hudson and his team at SDRplay! I’m very happy to hear how popular the RSP has become.

If you’re an RSP owner, or plan to be soon, make sure you check out the official SDRplay forum and the SDRplay Facebook group: both excellent resources backed by active SDR enthusiasts!

New improved API for the SDRplay RSP

Leave a reply

The SDRplay RSP software defined radio

Many thanks to Jon Hudson with SDRplay, who shares the following announcement:

We are pleased to announce release 1.8.0 of the API for the RSP. This is a major upgrade to the API with new features and an improved gain map which should result in improved performance over a key portion of the gain control range. Currently this API is available for Windows only, but versions for Linux and Mac OS and Android will follow shortly.

The API now incorporates automatic post tuner DC offset correction and I/Q compensation. This will almost completely eliminate the DC centre spike that was previously present in zero IF mode and also correct for amplitude and phase errors in the I/Q signal paths that can lead to in-band images when strong signals are present.

There is a new gain map for the RSP which should help improve the receiver noise floor for gain reduction settings in the range of 59-78 dB. To achieve this, the IF gain control range has been increased from 59 to 78 dB. In addition, the user can now turn the LNA on or off at any point within the IF gain control range. This means that the LNA can remain on for gain reduction settings of up to 78 dB, whereas previously the maximum gain reduction that could be attained whilst the LNA was on was only 59 dB. Being able to leave the LNA on will result in improvements in the receiver noise performance for gain reductions in the range of 59 to 78 dB. The upper 19 dB of the IF gain control range have now been disabled. In practice this part of the gain control range was useless as trying to operate within this region always lead to receiver overload even when signals were very weak.

To fully exploit the features of this new API release, we have also issued release 3.5 of the ExtIO plugin. This plugin will work with HDSDR, SDR sharp (releases 1361 or earlier) and Studio 1. Automatic I/Q compensation and DC offset correction will work with later versions of SDR sharp, but we will need to update the native plugin for users of these later versions to be access the new gain map.

Similarly, users of SDR Console will gain the benefit of automatic DC offset compensation and I/Q correction, but will not yet be able to access the new gain map. We hope that a version of SDR console that unlocks this feature will become available in the near future.

Until a new release of SDR-Console is available, you can copy the API into the SDR-Console installation directory…

from C:\Program Files\MiricsSDR\API\x64\mir_sdr_api.dll to C:\Program Files\SDR-RADIO-PRO.com\mir_sdr_api.dll

The API installer has also contains an extra certificate to be more user friendly for Windows XP, Vista and Windows 7 users.

The new API and ExtIO plugin can be downloaded from our website at: www.sdrplay.com/windows.html

Many thanks for sharing this, John! I’ll update my RSP today.

HDTV via an SDRplay RSP

2 Replies

Check this out: a tutorial on decoding ATSC HDTV via the SDRPlay RSP software defined receiver.

(Source: coolsdrstuff.blogspot.com)

One of the main reasons I got the SDRPlay RSP was its wide bandwidth. It can show up to 8 MHz of spectrum at once. I figured it should be able to watch TV. Turns out it can, but it’s only designed to receive DVB-T.

Unfortunately, they only use that in Europe and a few other places. In North America we use ATSC.

In this article I will show how to use it to watch ATSC.

This is one of the things I love about SDRs: in many ways, their applications are only limited by your imagination.
