uSDR Software Updated to V1.7.0

Thank you to Viol for writing in and letting us know that his uSDR software has recently been updated to V1.7.0. The uSDR software (not to be confused with the unrelated uSDR hardware) is a lightweight general-purpose multimode program for Windows that supports the RTL-SDR, Airspy, BladeRF, HackRF, LimeSDR, and other SDR radios.

Viol highlights the latest features added in the 1.7.0 update below:

  • Fobos SDR frontend native support, the very new SDR from RigExpert
  • bladeRF API v2.5.0 support, oversampling mode up to 122.88 MHz sample rate (do not forget to update FX3 firmware)
  • advanced IQ playback mode, precise timing and streaming
  • improved DSP routines and memory management, minimized CPU load
  • excellent ruler tool for spectrum frequency and amplitude measurements

FobosSDR: A New SDR Receiver with 100 kHz to 6 GHz Tuning Range and 50 MHz Bandwidth for $395

Recently we've seen that a new SDR from the Ukrainian company RigExpert has been released. The RX-only USB3.0 SDR is called 'FobosSDR' and it has a 100 kHz to 6 GHz tuning range, 50 MHz of bandwidth, and 14-bit resolution. Apart from a standard RF input, it also has two auxiliary input channels for coherent direct sampling and clock in and out ports.

In terms of software support, the FobosSDR supports HDSDR, and interestingly a very old version of SDR# (SDR# 1716) through a plugin. They also have a GNU Radio block.

The design is based on the LTC2143 ADC and uses a wideband RFFC5072 mixer on the front end which feeds into a MAX2830 transceiver chip.

RigExpert products are carried by a number of resellers across the world, but FobosSDR does not yet appear to be available from any that we checked. So far we have not seen any reviews or demonstrations of the product in action, but will update if we do.
