The February 2020 edition of Spectrum Monitor Magazine is out and Larry Van Horn (N5FPW) has written this in-depth review of the RSPdx (see pages 11-17)
In it, Larry writes “To me the proof of a radio’s true weight and metal is when you put it on the air and test it in real life monitoring situations.
I own an RSP-1A and have been very happy with its receiving capability above 500 kHz. On longwave frequencies not so much. The RSPdx SDR, however, below 2 MHz has been fun to play and DX with. I have added all sorts of longwave, AM BCB (including some trans-Atlantic MW stations) to my logbook.
In the longwave spectrum, for instance, during a half hour listening session, I added several new Non-Directional Beacons (NDB), including two new states and two Canadian beacons. I have also logged several longwave broadcasters from both Europe and Africa.”

Over on the popular “Ham Radio Crash Course” YouTube Channel, presenter Josh has made a comprehensive video showing the capabilities of the RSPdx. Josh says “The SDRPlay RSPdx software defined radio receiver is a lot of fun, providing all the features I think I’d need to listening to the amateur radio, broadcast and shortwave radio bands. SDRPlay offers multiple models to fit your feature and price needs”
Intrepid MW DXer, Bjarne Mjelde is well known for his arctic medium wave (AM) DXing which presents some of the most challenging conditions imaginable. He has taken time to put the RSPdx, through its paces in this detailed review in his latest blog post
In the report, he concludes that the RSPdx makes a good, inexpensive alternative to much more expensive receivers for MW and LW DX-ers. He also notes that unlike many alternatives the RSPdx can sample the entire broadcast band at once.
The January 2020 edition of the Radio Society of Great Britain’s monthly magazine RADCOM is out and features a review of the new RSPdx by Mike Richards.
Mike summarises: “The SDRPlay RSPdx is a welcome addition to the portfolio and is likely to have special appeal to those with an interest in the LF bands especially below 500kHz. The combination of the new 500kHz filter and the HDR mode gives a worthwhile improvement. ”
Many thanks to Mile Kokotov in Macedonia who posted this excellent demonstration video showing the power of the new RSPdx for long wave DXing. (You can visit Mile’s popular YouTube channel here)
Over on the Independent SDRplay Facebook group, he posted the following article:
“Amateur Radio is an interesting hobby with many different areas in which every radio tech lover can find himself and enjoy.
In addition to the already known amateur radio disciplines, many hams around the world are interested in the so-called “Broadcast DX-ing”.
They use radio receivers to “hunt” distant commercial radio stations on long waves (LW), medium waves (MW), short waves (HF) and very short waves (VHF).
In this video I will show you the “hunting” of long distance commercial radio stations on Long Waves (LW).
Every radio amateur knows that the reception of low frequencies (long wavelengths) is a particularly big challenge because there are a number of RF interference, atmospheric interference and industrial interference (man made RF-noise).
If anyone doesn’t believe it, he can try to catch some of these radio stations that I recorded on this video. Although their signals are relatively strong, try it out, and you’ll find that reception is not simplistic at all, even if you have a large external antenna and a modern radio receiver.
In this video I am using the newest model of SDR receiver from SDRplay (RSPdx model), and the antenna is home-made active mini-whip antenna with two transistors, mounted on a 6-meter high telescopic plastic mast.
The software is SDRuno from the same company, which together with the aforementioned SDR receiver make a real miracle for receiving in frequency range from 1 kHz up to 2000 MHz.
The large number of DSP plus HDR features and predefined filters, which can be manually adjusted to the specific reception conditions, allow high quality reception of distant radio signals that will impress even the most demanding DX-ers.
Watch the video and see for yourself. 73!”
Clint spends much of the year travelling the world and uses the opportunity to hunt Medium wave DX signals. He also writes articles for magazines including Radio User here in the UK.
Take a look at these recordings he made from here in the UK:
Over on Youtube, Rob aka “SevenFortyOne” has released a very nice video talking through some of the features of the RSPdx which will be on sale later in November 2019. He includes some demonstrations of it in action, picking up some longwave broadcast stations from across the Atlantic:
Youtuber Mile, Z33T has one of the few advanced samples of the new RSP2pro replacement – the RSPdx which will begin shipping later in November 2019.
He writes “Today I have received the new SDR receiver from SDRplay: the RSPdx, and was eager to turn it on and do some tests receiving on HF and VLF. Although at the moment my mini-whip antenna is not operational, I have connected some 20 meters wire as an antenna and start listening on VLF, LW, MW and HF… I have to say that SDRplay team did a good job with this SDR-receiver, putting better filters and redesigning front-end to improve dynamic range and enhance overall performance in relation to its predecessors RSP2 and RSP2pro. The new RSPdx is very good indeed. Especially on HF and below.”
