Many thanks to SWLing Post contributor, Dan Robinson, who shares the following video from Fernando Duarte highlighting the new Alfredi LAN-IQ SDR:

I can’t wait to check out Fenu’s full review of the LAN-IQ when it is posted on his excellent website. The screen seems to be very responsive and layout well thought through.

The Afedri website notes the following features and specifications:

  • Direct sampling
  • DDC – Digital Down-Conversion
  • 12- bit 76.8 MSPS A/D conversion
  • Stand Alone mode (AM, CW, SSB, NFM, WFM stereo, BPSK, QPSK demodulators)
  • Up to 2.2MHz recording and processing bandwidth
  • Waterfall display functions, when used with appropriate software
  • Recording and playback, when used with appropriate software
  • Sensitivity –  MDS -136 dBm at 500Hz bandwidth (0.03MHz-35MHz)
  • Sensitivity –  MDS -143.5 dBm at 500Hz bandwidth (50MHz-435Mhz)
  • USB 2.0 (Full Speed) interface
  • LAN interface for remote access
  • Compatible with: Linrad, Winrad, HDSDR, Studio1,  SDR Console (SDR-radio), CuteSDR, SdrDX, Quisk, PowerSDR_mrx
  • Powered from USB or external power supply 7-10VDC
  • Dimensions 120mm deep x 78mm wide x 27mm high
  • Unit cost – $339

The LAN-IQ can be connected to a PC via USB or Ethernet (at a 2400 kHz sample rate).

The Afedri website also has a few videos of the LAN-IQ in operation:

As you might have noted, the encoder knob seen in Fenu’s video is not standard but can be added at an additional cost and extended lead time. If I were to order the LAN-IQ, I would want the encoder knob as well.

Also, note that due to Covid-19 affecting the supply chain, Afedri SDR informs me that LAN-IQ availability will be adversely affected. If you would like to order a LAN-IQ, contact Afedri SDR via their website.

Video: Fenu demonstrates the BELKA-DSP receiver

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following video demonstration of the BELKA-DSP receiver by Fenu Duarte:

Thanks for sharing this, Dan.  I must admit, it seems the BELKA-DSP has some excellent receiver characteristics. I like the backlit display and the rugged, simple form-factor. It doesn’t have an internal speaker, but based on Fenu’s video, the audio sounds superb (especially if you’re using a quality amplified speaker like Fenu).

I had planned to review the little BELKA-DSP last fall, but simply had too many in-bound review transceivers. As I knock out some of these reviews, I might have to reconsider!

Alex Buevsky kindly supplied the English language manual for the BELKA-DSP last year. If interested, click here to download the PDF.

Fenu-Radio reviews an AirSpy HF+ Discovery prototype

Fernando Duarte of Fenu-Radio has just posted his review of the AirSpy HF+ Discovery SDR prototype.  I trust Fenu’s reviews because they’re always thorough and based on actual listening sessions.

In short, he’s quite impressed with the prototype. In many instances the Discovery outperformed his benchmark Winradio G33DDC Excalibur Pro. Quite an accomplishment for a $169 SDR!

Click here to read Funu-Radio’s full review.

I will evaluate a first production run AirSpy HF+ Discovery. Since it’s incredibly lightweight and compact, I believe I’ll try to even build a small portable SDR station around it. Stay tuned.
