SDRplay announces the acquisition of Studio 1 SDR software

SDRplay Limited has today announced that it has reached an agreement with Sandro Sfregola, (formerly CEO of SDR Applications S.a.s.) to acquire all Rights, Title and Interest in Studio 1 a leading software package for Software Defined Radio applications.

Jon Hudson, SDRplay Marketing Director said: “We are delighted to have reached this agreement with Sandro to acquire Studio 1. Studio 1 is the perfect complement to our SDR hardware products and gives us the ideal platform to deliver a complete class leading SDR solution for our customers. We look forward to working with Sandro and further developing Studio 1 to unlock the full capability of our current and future products”.

Hudson added: “Studio1 has established a strong customer base with users of many other SDR hardware products. Studio 1 will continue to be available as a stand-alone product from WoodBoxRadio http://www.woodboxradio.com/studio1.html for the foreseeable future , but we also look forward to further developing Studio 1 to specifically benefit present and future owners of our products”

Sandro Sfregola added: “I am very pleased to have reached this agreement with SDRplay. The long term future for SDR lies in complete end to end solutions and I feel the SDRplay RSP combined with Studio 1 software gives users an outstanding combination of performance and affordability”.

About Studio 1:

Studio1 was developed in Italy by SDR Applications S.a.s. and has hundreds of happy customers around the world.

My Comments:

Of course, I believe this is a very good move for SDRplay. Studio 1 is a very well-respected application and, though I’ve never tested it myself, I’m very impressed with it’s interface. I’ve also received many positive comments about Studio 1 from Perseus owners.

This will give SDRplay a great platform to have native SDR applications for their current and future products. I’m sure they’ll continue to support and develop Studio 1 for all of its supported receivers:

  • The Elad FDM-S1, FDM-S2
  • Microtelecom Perseus
  • PMSDR
  • RFspace SDR-IQ, SDR-14
  • SRL QS1R
  • Funcube Dongle

SDR Touch works on most recent Android Phone or Tablet devices.

A QS1R replacement in the works?

Many thanks to SWLing Post contributor, Ken McKenzie, who noticed the following message from Phil Covington (of Software Radio Laboratory LLC) on the QS1R Yahoo group:

I am working on a replacement for the QS1R that will be less expensive, yet
use updated components. I am hoping to have them in production by the end of March.

Ken noticed that the message was originally dated about one month ago, so I’ll follow-up with Phil and see how much progress has been made. The QS1R was a well-respected SDR that had been on the market for several years. It would be great to see an updated version on the market.

One year with the TitanSDR

TitanSDR-VOG

Last year, I reviewed the TitanSDR Pro by the Italian manufacturer, Enablia,. I was very impressed with not only this receiver’s performance, but also its accompanying application’s user interface. I also noted in the review that the TitanSDR is pricier than many other benchmark SDRs on the market ($1380-1970 EUR) but it is, after all, essentially a military-grade SDR that has been ported to the enthusiast/ham radio market.

I’ve been using and testing updates to theTitanSDR Pro for a year now, and I continue to be just as impressed with this receiver––and, especially, with the company who manufactures it, Enablia.

TitanSDRPro-3

I wondered at the time of my initial review how supportive Enablia might turn out to be; I knew time would tell.  Since my original review last year, Enablia has been regularly updating the TitanSDR application, adding many features requested by its users.  This shows a remarkable degree of responsiveness, and I now feel safe to say that that Enablia is an exceptional manufacturer with an exceptional product.

Only recently, I received an update which added two notch filters per narrowband channel, memories that retain AGC and notch filters settings, and sessions that retain AGC settings. I understand Enablia is also preparing updates that improve upon memory management, user interface, audio defaults, as well as offering a few tweaks to the existing feature set.

Overall, Enablia developers are certainly making this signal intelligence SDR cater to the ham radio and enthusiast market even better than before.

Though I use a number of SDRs, I reach for the TitanSDR any time there are multiple-band openings since it can record spectrum and audio across the entire LW/MW/SW landscape. Unlike my other SDRs, it’s not limited to an (already generous)  2-6 MHz recording/listening window.

For example, on Thursday night I had a lot on my listening/recording plate as there were a number of band openings. I had the TitanSDR tuned to:

  • the 31 meter band,
  • the 20 meter ham radio band,
  • the 49 meter band (specifically monitoring South American stations), and even
  • the mediumwave band.

The TitanSDR was recording spectrum on the 49 meter band while I made this AF recording of the Voice of Greece on the 31 meter band (9420 kHz, starting around 00:26 UTC on April 8, 2016):

Surprisingly, all of this recording wasn’t taxing my PC, nor the TitanSDR.

The TitanSDR application is highly stable and uses resources efficiently. Indeed, in the past year, to my knowledge the TitanSDR application hasn’t crashed even once, despite my rigorous demands of it. Since it runs nearly 24/7 in my shack, on a four-year old PC (third generation i5 Win 7), that’s saying a lot.

SWLing Post reader, Tony Roper, is also a heavy TitanSDR user and recently posted this 30+ minute video demonstrating some of the TitanSDR’s new features. Note that his screen capture software produced fairly low audio, so you’ll need to turn up the volume to hear his commentary:

In short, I stand by my conclusions drawn last year in my TitanSDR review:  although pricey compared to the competition, for those who can afford the price tag, the TitanSDR is a worthy hard-core DX machine that is especially useful to need a receiver with a bullet-proof front end, to weak-signal DXers, and to radio archivists like yours truly.

A $38.99 RTL-SDR with 100 Khz – 1.7 GHz coverage

RTL-SDR

Many thanks to SWLing Post contributor, Bill, who recently shared a link to this very affordable RTL-SDR with wideband coverage.

I am not at all familiar with this model, but I do like the enclosure and the fact it has both an HF and UV antenna jack. This must be one of the least expensive SDRs on the market with HF coverage.

Here are a few details per Radioddity.com:

Features:

  • 100% Brand New And High Quality
  • Using the RTL2832 idle channel, broadband connection impedance isolation transformer provides the signal to the signal receiver HF HF bands.
  • Increased input low-pass filter to improve noise performance of the machine. At the same time, it retains the original V / UHF band reception, creative use of studded way to achieve RTL2832 + R820t circuit board assembly and connecting circuits increases
  • Further improve the overall performance of the circuit.
  • In the homemade circuit board also surrounded, surrounded reserved some help to further develop the pads. The entire circuit is loaded inside a small aluminum to further improve the performance of the overall circuit interference by aluminum shielding.

Package Contents:

  • 1 x 100KHz-1.7GHz full band UV HF RTL-SDR USB Tuner Receiver/ R820T+8232 Ham Radio
  • 1 x USB cable
  • 1 x antenna
