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!

Software support

  • ExpertSDR2
  • CW Skimmer
  • Skimmer Server
  • Third party software using ExtIO library
