Simon Brown Compares the Airspy HF+ against the RFSpace NetSDR on SDR-Console V3

Simon Brown who is the author of the popular SDR-Console V2/V3 software has received an early review version of the Airspy HF+ and has uploaded some screenshots comparing it with the RFSpace NetSDR. The NetSDR is a high performance 16-bit DDC SDR with frequency range of 10 KHz – 32 MHz, and a bandwidth of up to 1.6 MHz. The base price of the NetSDR is US $1449.

The Airspy HF+ on the other hand is based on a polyphase harmonic rejection mixer design with 18-bit DDC and has a frequency range of DC – 31 MHz and 60 – 260 MHz, with a maximum bandwidth of up to 660 kHZ. It is not yet released, but is expected to be about US $149 shipped from China.

Simon’s screenshots show that despite its low cost the HF+ seems to perform just as well as the more expensive NetSDR.

If you’re interested in the HF+ we also have our own review available here.

New Airspy HF+ Pics and Sensitivity Test

The Airspy HF+ is an upcoming product from the Airspy team that is intended to be a high performance HF/VHF receiver at a low price. Its frequency range will be DC to 31 MHz, and 60 to 260 MHz and the bandwidth will be about 660 kHz. So why choose the HF+ over the Airspy R2, Mini or SDRplay which all have larger frequency ranges and bandwidths? It seems the focus of the HF+ is to be an extremely high dynamic range receiver. This means that strong signals should almost never overload the receiver making it very good for DXing weak signals (listening to weak signals from very far away). On other receivers once you turn the gain up strong signals can block reception of the weaker ones.

Recently we saw the release of some of the first 3D renderings of the product. Now finally we have a photo of the actual PCB which is shown below. The RF sensitive innards are hidden away within a shielding can, but we know from the product page that inside are the switches, filters, tuner, ADC and 18-bit DDC.

Also, over on Twitter, @lambdaprog, lead creator of SDR# and of the Airspy HF+ has uploaded some sensitivity tests. It seems that sensitivity will be at least -136 dBM at 20 meters, as a -136 dBm signal still comes in with 21 dB of SNR. Similar sensitivity results are obtained on the FM Band.


The Airspy team have sent us a sample unit from an early manufacturing test and we hope to have a full review available a few weeks after we receive it.

First Renderings of the Airspy HF+ Revealed

Back in February of this year we first heard about the Airspy HF+, which is an upcoming product from the Airspy team that is intended to be a high performance HF receiver at a low price. Over on the Airspy HF+ website the first (rendered) image of the unit has recently been released. We’ve also managed to get some additional renderings from the Airspy team which we show in the image slider below.

The enclosure is CNC carved aluminum with two SMA ports on one side, and a USB port on the rear. Since the HF+ actually has the capability to tune up to 260 MHz it uses two SMA inputs, one for an HF antenna and one for a VHF antenna. Inside the RF circuit is shielded again with a shielding can to protect it from USB noise.

The tweet below also appears to show some grounding improvements made to reduce USB noise.

Other recent tweets from prog (the creator of the Airspy HF+) indicate that the hardware is ready, and show that streaming from with SpyServer from a RPi3 is functional. Hopefully we should be seeing this unit release for sale soon.

ColibriNANO: A New 10 kHz to 500 MHz Direct Sampling Receiver

The ColibriNANO is a new software defined radio that is currently available for pre-order and is expected to be ready for delivery by the end of April 2017. The specs show that it is a direct sampling receiver (no tuner), which can receive from 10 kHz to 500 MHz in oversampling mode, and from 10 kHz to 55 MHz in standard mode. It uses a 14 Bit ADC which provides up to 110 dB’s of blocking dynamic range, and can run with a sampling rate of up to 3 MHz. The press release given to us reads:

New ColibriNANO SDR USB Receiver with a 14-bit ADC .01-500MHz

Kirkland, WA, USA —March 27 th , 2017 –

Vasily Vasiliev, Chief Hardware Engineer of Expert Electronics is pleased to announce availability of new ColibriNANO 0.01-500 MHz receiver in late April, 2017.

Notable features include the blocking dynamic range (BDR) ~110dB, native .01-55 MHz coverage with up to 500 MHz in oversampling mode, low pass filter (LPF) <60 MHz, full compatibility with HDSDR, legacy SDR#, and ExpertSDR2 software.

Supported platforms are Windows® XP-10, Linux and Web-client for HTML5 browsers.

No existing USB SDR receivers combine high sensitivity and broad dynamic range. Remote operation (TCP/IP) interface is built-in and offers plug-and- play solutions for Amateur, Commercial and Government applications.

Currently we see that the ColibriNANO is selling for $249.95 USD on the nsiradio.com website. We’ve also seen the following description on the sunsdr.eu website:

With the new ColibriNANO you will be able to enjoy LF, MW and Shortwave listening in many different ways. For example you can record the entire medium wave band using 1.5 MHz sampling rate, decode CW using CW skimmer, remote control the ColibriNANO by plugging it into our RPI server. There are an endless range of applications for this small SDR. All this in a tiny USB stick!

The ColibriNANO features a Texas Instruments ADS4145 14 bit direct sampling ADC and a built in low 55 MHz pass filter that can be bypassed to receive signals up to 500 MHz (external filters  like the our 2m filtered preamp recommended).

CW skimmer and Skimmer With the external ExtIO library the ColibriNANO can be used with third party software like HDSDR etc.

This is not a cheap USB dongle found on Ebay, this high quality SDR receiver is developed by Expert Electronics and features a sturdy aluminium chassis, ESD protection, USB 2.0 interface and a quality SMA antenna connector.

Best of all, the ColibriNANO travels in your pocket and only needs your computer and an antenna! Its the ultimate portable SDR receiver!
