Arinst Dreamkit SDR now on sale for $230 + Shipping

About a month ago we posted about the Arinst Dreamkit, which was an unreleased Russian made portable receive only SDR with 16-bit ADC, 1 - 3100 MHz tuning range, up to 5 MHz instantaneous bandwidth, and very fast scanning capabilities.

Reader 'sunny' has written in and informed us that the Arinst Dreamkit is now released and available for sale on both eBay and Aliexpress. The pricing is $230 + shipping costs. Sunny notes that the manual is only in Russian, and currently it does not have any digital decoding capabilities, and no preselector on the input.

Arinst SDR Dreamkit: A Portable RX SDR with 16-Bits, 1 – 3100 MHz Range and 5 MHz Bandwidth

Thank you to reader 'sunny' who has written in to share a new software defined radio that he has found being previewed on YouTube. The SDR is the Arinst SDR Dreamkit, a Russian made portable receive only SDR that will have a 16-bit ADC, 1 - 3100 MHz tuning range, up to 5 MHz instantaneous bandwidth, and have very fast processing which can scan the spectrum at 20 GHz per second. It also comes with a built in 3.9" touchscreen and loudspeaker.

Arinst are a Russian company that designs, produces and sells affordable portable spectrum analyzers, vector network analyzers, power amplifiers and antennas.

The Dreamkit is not yet available for sale but reader sunny has indicated that the pricing will be ~$250, although we cannot confirm that information. In a YouTube comment the developer only writes that it will be slightly more expensive than the Malachite SDR, for which an original non-clone unit sells for around $200.

We have not seen any announcement of the product on their website, but on their first YouTube video for the product they write some specs (translated from Russian):

  • There is no preselector.
    • Possibility to supply preselectors and source repeaters via SMA antenna connector. It also provides for the generation of a code message for each frequency range by pulse modulation of the supply voltage supplied to the antenna connector.
  • Operating frequency range - 1-3100MHz
  • Input impedance 50 Ohm.
  • ADC capacity - 16 bits, effective 13 bits.
  • Instant scan bandwidth - 5 MHz, sampling rate: 2 IQ channels at 6 MHz.
  • Scanning speed over 20 GHz per second.
  • Audio: built-in loudspeaker, headphones, bluetooth (optional).
  • Battery life up to 3 hours.

From the English demo video shown below, the interface looks very slick, customizable and with a very responsive refresh rate. The video shows off the features which include all the standard demodulation modes, an RDS decoder, 12V 100mA bias tee, and the ability to connect to a PC and run it on HDSDR.

It appears that they plan to sell additional preselectors and LNAs that will be powered via the 12V bias tee. An interesting point is that it appears that they will control the external devices via a some sort of modulated pulse on the coax.
