Check out the new scheduler functionality in SDRuno V1.41

Many thanks to Jon Hudson with SDRplay who shares the following information about the latest release of SDRuno on the SDRplay blog:

Try out the new features in SDRuno V1.41 released today

SDRuno V1.41 was fully released today.  It includes the much requested full scheduler facility which allows you to set up numerous recording events for your RSP.  As well as providing all the expected calendar options (time of day, date, start and stop times, repeating options and so on), you can also set the ‘profile’ for each recording – this allows you to pre-set frequencies, bandwidths, demodulator options (AM/FM/USB/LSB etc.), choice of filters and antenna port selection.  Additionally you can choose the settings for connectivity to other third party software or the running of a specific plugin.

Added
• New Scheduler panel which replaces the old “Recorder” panel (launch using the SCHEDULER button in the main panel).
• A new autolayout to include the scheduler (for screen resolutions of 1920×1080 and above).
• Backup and Restore of the ini file settings (access via the main panel OPT menu)
• Screenshot button has been added to the SP1 title bar
• IQ wav files can now be used in plugins
Changed
• Autolayouts now take account of the taskbar location and size.
• Autolayouts have been improved to take account of higher resolutions.
• Saved workspace notification moved to the status bar.
• Memory Panel will now prompt to save any changes made when switching to another memory
bank.
Fixed
• Decimation and the LOLOCK state are now correctly saved and recalled within a profile.
• Main panel version tooltip now displays correct information.
• The step size could be set incorrectly when using non-FM modes and pressing any of the FM sub
mode buttons.
• ADS-B/DAB mode now handles when in both band-framed mode and also when the LO is locked.
• Bugs associated with wav file playback
• When loading a profile, the last used memory bank field will update correctly
• Saving a profile will now update the displayed loaded profile field correctly
Known Issues
• SP2 CWAFC drift issue (Zoom/window size/freq display)
• IF output mode disabled SP1 spectrum mouse clicks
• Occasionally if SDRuno is closed whilst a plugin is still running, it may not close properly. This may
necessitate a PC reboot to fix it.

Mike compares four active mag loop antennas

Many thanks to Jon Hudson who shared the following on the SDRplay Facebook page:

In this new video, Mike Harwood compares 4 different active mag loop antenna at various frequencies up to 52MHz using two SDRplay RSPduos which allowed simultaneous spectrum snapshots of the 4 loops in action with real signals.

These are loops from Bonito, Cross Country Wireless, LZ1AQ and Wellbrook.

This is the second of Mike’s antenna comparison videos. He welcomes comments which will help shape the content for future antenna experiments:

Mike Harwood explores active magnetic loop antennas with SDRplay

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


Introducing a new series of videos comparing the performance of wideband active loop amplifier/antennas for HF frequencies and below. In this introductory video, Mike Harwood shows how an RSPduo enables a real-time comparison of two antennas – in this demo, he uses a Wellbrook 1530AN and one of his own compact loop creations. You can see that he has lined up several other active loop antennas/amplifiers to try in future videos, including the Bonito Megaloop FX, the LZ1AQ amp and the Cross Country Wireless amp.

SDPlay will endorse antennas which work well and formally recommend them on its website antenna suggestions page: https://www.sdrplay.com/antennasuggestions/

This is one of many videos from SDRplay – makers of the RSP family of SDR radios. See the full list of SDRplay videos and applications documents on: https://www.sdrplay.com/apps-catalogue/

The RSP family of SDRs from SDRplay cover 1kHz to 2 GHz with no gaps and give up to 10MHz spectrum visibility.

SDRplay is a UK company. The RSP SDR receivers are made in the UK and can be purchased for worldwide delivery directly from http://www.sdrplay.com/ (click on purchase and select your country to view shipping costs) or you can buy from any of our worldwide resellers listed here: http://www.sdrplay.com/distributors/ Many of the resellers offer local free shipping and/or local language technical support.

Video demonstrating SDRplay remote operation

The SDRplay RSPduo

(Source: Jon Hudson at SDRPlay)

This video guide demonstrates the new RSP TCP server software which is now included in the latest Raspberry Pi SD Card image. The video shows how easy it is to set up an RSP at a remote location for access over the internet.

Click here to view on YouTube.

The video uses a Raspberry Pi at the remote location, and a Windows PC running HDSDR back at home base.

We are only demonstrating the Raspberry Pi version of the server here. Also, we are demonstrating extended mode (enabling the full RSP ADC resolution which only works with software which supports an EXTIO interface). Other (non EXTIO compatible) RTL-SDR software will also run via the server on an RSP device – but in “normal mode” meaning that the data resolution will be restricted to 8 bits.

SDRplay announces the RSPduo: A 14-bit Dual Tuner SDR

(Source: SDRplay Press Release)

SDRplay announces the RSPduo – A 14-bit Dual Tuner SDR

Today at the Dayton Hamvention, SDRplay Limited is announcing the launch of a new Software Defined Radio product – the RSPduo.

The RSPduo is a radical new addition to the RSP line of SDR receivers from SDRplay. Architecturally, it is different from any previous RSP in that it features dual independent tuners, both piped through a single high-speed USB 2.0 interface.

The SDRplay RSPduo is a dual-tuner wideband full featured 14-bit SDR which covers the entire RF spectrum from 1kHz to 2GHz giving 10MHz of spectrum visibility. Initially using Windows based ‘SDRuno’ supplied by SDRplay, you can simultaneously monitor two completely separate 2MHz bands of spectrum anywhere between 1kHz and 2GHz.

Superficially the RSPduo looks identical to the highly popular RSP2pro and will be able to operate in a very similar way.

However, it also allows a completely new and exciting set of usage scenarios such as:

  1. Simultaneous monitoring of two widely spaced bands – e.g. 40m (HF) and 2m (VHF)
  2. Mixing and matching applications simultaneously – e.g. ADS-B and ATC scanning
  3. Phase and time coherent demodulation of two receivers

Scenario 3 is very difficult to achieve with two separate USB devices because of the uncertainty of USB latency. The RSPduo overcomes this limitation because all traffic goes through a single USB interface, thus enabling the possibility of the development of various types of diversity demodulation such as: spatial, frequency and polarisation which can bring
huge benefits in terms of improved performance.

Jon Hudson, Marketing Director at SDRplay commented:
“As well as adding a second independently controlled tuner, which in itself, offers a whole new set of exciting usage possibilities, the SDRduo features 14bit ADCs and a completely re-designed RF front end. These changes provide better RF selectivity and even more dynamic range, offering outstanding performance under extremely challenging reception conditions. The combination of performance and features makes the RSPduo our highest spec RSP yet and sets a new benchmark in the sub $300 SDR market”

Due to its exceptional combination of performance and price, the RSP family of receivers have become very popular and the RSPduo provides the next level of functionality for both amateur radio enthusiasts as well as the scientific, educational and industrial SDR community.

As well as being demonstrated at Hamvention, the RSPduo is available direct from SDRplay or via SDRplay’s network of channel partners and resellers

The RSPduo is expected to retail at approximately $279 USD (excluding taxes) or £199 GBP (excluding taxes).
