Elektor magazine have just published a review of the RSPdx: https://www.elektormagazine.com/news/sdrplay-rspdx-review
Over on The SWLing post, a self-proclaimed “oldster” who prefers knobs and switches, tries out an SDR for the first time – the RSPdx – and he writes: “To use a metaphor, if you conceive of a conventional shortwave receiver as treasure map which you use to search for hidden on-the-air treasures, the RSPdx is like ground-penetrating radar. Instead of seeking active stations by tuning across the spectrum, you can see all the active signals in a band displayed as peaks. Just use your cursor to float the indicator line over the peak you want, click, and you’re there. Move your cursor to another peak, click, and you’re there. It’s quick and easy, slick and fast, and the audio coming through my headphones was very, very satisfactory.”

In this new video by Gilles from the popular Canadian-based OfficialSWLchannel, SDRplay comes out tops with all 3 RSP receivers featuring in his “top 10”:
We just had to show this recent post from Italo, IK3UMZ from the independent Italian SDRuno Facebook group. He has had spectacular results choosing between two medium wave (AM broadcast) stations sharing the same frequency (918kHz) – this video describes his setup and lets you see how well diversity tuning with the RSPduo and SDRuno combination really works so well:
In this video, John Fallows, VE6EY, author of the popular “Making it up” blog, shows HF diversity tuning in action with excellent results. He compares the performance of the low cost SDRplay RSPduo dual-tuner SDR receiver very favourably with the highly acclaimed Apache Labs Anan 7000 DLE MkII SDR.
In this demonstration he uses two active loop antennas separated by approximated 100 feet (30 metres) as he receives a weak 25m band broadcast signal over a 13,000 km path.
Update later on October 23rd: Just after I posted this, John published his blog describing all this in detail: https://play.fallows.ca/wp/radio/software-defined-radio/anan-versus-rspduo-on-hf-surprising-results/
There’s also a great audio interview with John being interviewed on Hamradio Workbench Podcast. John describes Diversity reception and how he sets up his antennas. He covers the difference between array gain, diversity gain and phase diversity. Start listening one hour and thirteen minutes into the podcast here: https://www.hamradioworkbench.com/podcast/hrwb-140-diversity-reception
(Starting at one hour 41 minutes and 45 seconds in to the podcast, John talks about how well the RSPduo and SDRuno do diversity 😉 )
Another great video posted in November: Take a look at this excellent RSPduo demo over on the Italian SDRplay Facebook group – it shows how you can select between 2 HF stations transmitting on exactly the same frequency by adjusting the phase setting: https://www.facebook.com/100001379902566/videos/1209143166582349/
We have now clocked up nearly 100 reviews of the RSP1/RSP1A on eHam reviews with an average score of 4.6 stars (out of 5), Many thanks to everyone who has rated us on there. You can read these reviews by going to: https://www.eham.net/reviews/view-product?id=12358
The RSPdx also scores 4.6 and the RSPduo scores 4.8
Reviews tend to tell you “warts and all” where we are good and where we fall short of expectations. We take all feedback seriously and appreciate our customers for their honesty and enthusiasm.
A very complimentary video was posted today which describes how the RSPdx compares with another popular alternative which has many complementary strengths. There is room for all in this wonderful world of SDR reception 🙂 :
The 2021 edition of the World Radio and Television Handbook is now available for purchase and includes a review of the RSPdx in which the author comments ‘This receiver excels at all types of monitoring whether it be broadcast, amateur, utility, L-Band and more. With decent aerials there is not much out there than can escape the SDRplay RSPdx. It impresses with its good overall performance, wide band coverage, small footprint, all mode reception, and powerful free software; it is also so reasonably priced that it’s hard to think what’s not to like about this great little receiver. ‘

Many thanks to Matt from Tech Minds who has made this video which shows how RSPs are designed and made:
This video had proved very popular and so here’s a bit more about Walkbury Electronics in Peterborough who were our first of our two UK manufacturing partners. Walkbury continue to manufacture the RSPduo for SDRplay. (Our other partner is TT Electronics in Hartlepool ) We are grateful to both these great companies for managing to build RSPs throughout the Covid-19 pandemic this year.
In his latest blog, John VE6EY describes the success he had when he connected noise probes to the second channel on his RSPduo, with the main antenna on channel one. To summarise his findings…. “Voila! An RSPduo noise canceller that really does the job.”
