The Airspy HF+ Discovery Wins the WRTH 2020 Award!
We did it again! 2019 was a year of revelations and discoveries for us. Short after launching our ground-breaking HF receive technology incarnated by the Airspy HF+, we worked on polishing and improving the overall performance while skimming everything unnecessary in order to reduce the cost to a minimum and democratize High Performance HF receive with a truly affordable radio.
Our unit got a glowing review from the well respected WRTH in their 2020 edition. The competition was fierce, but here we are!
example, has a BDR of about 118dB at 10MHz and is slightly better than that at higher frequencies. Rather oddly the claimed figure of 110dB for the Discovery appears to be very conservative. Although it is a difficult parameter to measure accurately and requires high-grade test equipment, we estimate that the true figure is around 116dB at 10MHz.
Overall, we find it remarkable and very commendable that a small and relatively unassuming plastic box should turn out to be a radio receiver with a spectacular combination of performance and versatility. And at its very affordable price point, the ratio of price to performance of the Discovery could fairly be described as stratospheric. It is highly recommended. ”
Schwergewicht von 30 Gramm: Airspy HF+ Discovery (German)

A Heavyweight at 30g: The Airspy HF+ Discovery, by Nils Schiffhauer
Nils Schiffhauer, DK8OK is used to review top end SDR solutions for the most prestigious specialized press outlets got a chance to try an Airspy HF+ Discovery and he wrote an extensive article for Radio User Magzine. The extensive review is brought to you courtesy of Radio Enthusiast.
The Discovery shines with less noise, and, astonishingly, less crackle. In at least 80% of these diffi cult cases, intelligibility with the Discovery is clearly better. With very few stations, this receiver will even make the difference between understanding the identification of a station and not copying it. In August, I also tested the Discovery with the most ‘demanding’ band, the Very Low Frequency range (VLF). Here most SDRs – and certainly the majority of budget SDRs – reach their limits, lacking sensitivity and filling up the band with internally-generated signals. Thanks to a newly developed input section to start at even 500Hz, this receiver shows outstanding strong and clean signals from as far as the US Navy in Australia. ”
Larry Van Horn N5FPW’s extensive review of Airspy HF+ Discovery
Since the publication of the excellent review by Fernando Duarte, we had to up-scale our logistics for delivering the much awaited Airspy HF+ Discovery. Larry Van Horn had a pre-order placed at Airspy.US and planned an independent review for The Spectrum Monitor magazine. A few weeks after receiving his unit, his words were heart warming:
Fenu Radio reviews the Airspy HF+ Discovery
After the successful launch of the Airspy HF+ (Dual Port) last year, we received a lot of requests to bring this new level of performance into a smaller form factor. Not only we reduced the size of the HF+ by more than half of the PCB surface, but we also developed many filtering options and dynamic range enhancements to meet the requirements of the most demanding professionals and monitoring enthusiasts. Fernando Duarte, the owner of Fenu-Radio.ch followed this development since the beginning and helped defining the performance standard over multiple R&D iterations. Here’s what he says about the Airspy HF+ Discovery…
World Radio TV Handbook awarded Airspy HF+ “Best Value” for 2019
Early this year, we were contacted by the WRTH gentlemen who asked for an Airspy HF+ unit to review. A few months later, we were surprised by the award!
Basically, they took our word for it and tested the Airspy HF+, first using lab instruments, then they compared it to a Racal RA3791 in severe band conditions that other reviewed “budget” SDRs struggled to handle.
Here’s what they say…
RTL-SDR.com Blog performed an extensive performance shootout of Airspy, SDRPlay and HackRF
The results were not surprising for the folks who already tried the devices in question, but have shown once again how Airspy shines with its top notch performance. The shootout demonstrated how our receiver architecture is keeping an excellent performance on all bands where the other competitors encountered imaging, aliasing and severe loss of sensitivity.
Bob Grove W8JHD reviewed Airspy R2 on The Spectrum Monitor
Bob Grove W8JHD of The Spectrum Monitor fame discovered the Airspy R2 and the SpyVerter a month ago, and wrote an excellent review on The Spectrum Monitor Magazine. Bob confirms what the lab figures say about Airspy and place it among the high performance communication receivers that shape the SDR scene today. Reprinted with permission from the publisher.
Most recently produced and receiving well-deserved attention is the Airspy, with 24-1750 MHz continuous fre-quency coverage. And, if you’d like frequency coverage all the way down to audio (about 1 kHz depending on the band-width setting), their accessory SpyVerter provides just that. Its typical image-free span is about 8 MHz, a nice spread for active frequency hunting. ”
Andy Talbot, G4JNT reviewed Airspy on the RSGB RadCom Magazine
Andy Talbot G4JNT of the RSGB took his Airspy apart and probed its spectral purity, strong signal handling capability as well as the ability to lock to external clock references. His verdict was clear:
The Airspy is a robust, well made little unit that offers a wider frequency span and tuning, better dynamic range and fewer spurii than the low cost dongles. It is unique in its ability to take in an external reference signal and, when the absolute calibration issues are finally sorted (and it is ‘only software’) will offer a very powerful accurate frequency detection and calibration tool too. ”
Mike Richards reviewed Airspy R0 on RadioUser Magazine
Mike Richards wrote an extensive review of the Airspy R0 where he details his findings. I’ll take his word for it: We have got a hit! The PDF article is provided courtesy of PW Publishing Ltd. Thanks Andy!
The Airspy is a very welcome new SDR receiver that is backed with a host of advanced features. The combination of the 10MSPS sample rate and a 12-bit ADC makes the Airspy a particularly attractive proposition. Even if you do not have a fast enough PC for the 10MSPS rate, the 2.5MSPS setting still provides very good performance and a 2.5MHz tuning band, which is more than most SDR receivers.The Airspy combined with SDR# gives you an immensely powerful receive system at your fi ngertips at a very attractive price. ”
