World Radio TV Handbook awarded Airspy HF+ “Best Value” for 2019

    • Early this year, 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…
      We carried out some tests on the amateur 7MHz band when a major contest was in progress and some extremely strong local signals were encountered. Using a full-size 7MHz three-element Yagi antenna at 30m (90ft) we expected major problems of overloading and spurious responses but found none whatsoever apart from very occasional and small increases in the local noise floor when an extremely strong local CW signal was encountered. This was a remarkable performance for any receiver, let alone a low-cost SDR, and one which many high-grade professional receivers from an earlier era would have found difficult to emulate. Another interesting point to emerge from the listening tests is that the Airspy sounds remarkably ‘quiet’ and unfatiguing in use, unlike many SDRs in its overall price class. This is presumably the result of careful design of the DDC and audio system.

Team RTL-SDR.com performed an extensive performance shootout of Airspy, SDRPlay and HackRF

    • The Good, the Cheap and the Hacky! 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 (himself!) 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 numbers say about Airspy and place it among the high performance communication receivers that shape the SDR scene today. Reprinted with permission from the publisher.

  • Andy Talbot, G4JNT reviewed Airspy on the RSGB RadCom Magazine

      • Andy Talbot of the RSGB, who already wrote about competing solutions, took his Airspy apart and probed its spectral purity, strong signal handling capability as well as the ability to lock to external clock references. He was clear: Airspy has a “Much higher performance than your average dongle…”.

  • Mike Richards reviewed Airspy on RadioUser Magazine

      • Mike Richards wrote an extensive review of the Airspy One as he did for competing solutions. I’ll take his word for it: We have got a hit! The PDF article is provided courtesy of PW Publishing Ltd. Thanks Andy!

Some measurements done by Leif Asbrink SM5BSZ

    • These tests clearly show how Airspy compares to some cheap and other expensive SDRs. Only a 14bit DDC radio that costs > $500 can beat Airspy, and they are a couple of dB away!
