Lightweight Windows Software uSDR Updated to Version 1.5.0

Since 2021 we've posted about Viol Tailor's "uSDR" (microSDR) software a couple of times. uSDR is a lightweight general purpose multimode program for Windows that supports the RTL-SDR, Airspy, BladeRF, HackRF and LimeSDR radios. The software can be downloaded from SourceForce.

Viol notes that recently the project has been updated to V1.5.0 which brings the following new features and changes.

  • lock device frequency on zoom option
  • keep waterfall history – the very great option, do not lose any rare signals
  •  advanced passband IQ recorder
  • passband IQ TCP server for remote processing, C/C++ client source examples included
  • advanced audio player, auto selectable sample rate, separate left/right channels
  • CTCSS decoder
  • markers import option convenient for merge markers 
  • Ctrl+Shift+Drag Up/Down – change spectrum magnitude offset
  • Ctrl+Shift+Mouse Wheel – change spectrum magnitude range (vertical zoom)
  • Ctrl+Mouse Hover – highlight nearest marker
  • Ctrl+Double Click– tune to highlighted nearest marker
  • band plan visualization, simple text format
  • frontend interface improvements
  • GUI improvements
  • spectrum and waterfall popup menus improvements
  • a lot of bug fixes

Video Tutorial: Decoding HD Radio on Windows with nrsc5-gui

Thank you to "Double A" for submitting his video that shows how to install and run the RTL-SDR compatible HD Radio decoder nrsc5-gui on a Windows machine. We've posted about nrsc5-gui and the modified nrsc5-dui software in the past, however despite being Windows compatible, it has only been simple to run on Linux.

In his video Double A shows us how to download and extract the files, how to set up the Windows mingw environment which is required to run the software, and where to place a required dll file dependency. Finally he demonstrates the software in action, running on his Windows machine.

Lightweight Windows Software uSDR Updated to Version 1.4.0

Back in July we posted about the release of Viol Tailor's "uSDR" software, which is a lightweight general purpose multimode program for Windows which supports the RTL-SDR, Airspy, BladeRF, HackRF and LimeSDR radios. Recently Viol has updated the software to V1.4.0. The new release brings SDRplay support, and various performance and GUI improvements listed below.

The software can be downloaded from SourceForce.

  • customizable tool panel behavior (fixed, floating, undocked)
  • SDRPlay frontend support (API v.2.13)
  • RTL-TCP streaming interface support, presets quick switch (server, port, description)
  • high precision Wav IQ file play back
  • support RIFF 8, 16, 24 and 32 bits integer, 32 bits float, FR64 file formats for playback
  • recognize Wav IQ file central frequency for play back
  • frequency offset (shift) for x-verters
  • swap IQ (invert spectrum) option
  • improved FFT spectrum calculation and visualization
  • waterfall color map range may be changed manually on the spectrum window as well as on tool panel, also included the auto scale option
  • color map palette can be customized and fast switched, palette presets are included
  • FIFO buffer size (IQ history time) may be changed on the fly, all memory allocations are under hood, no losses of previously stored history 
  • pass band may be attachment to global frequency as well as to local baseband frequency or to screen position
  • squelched threshold control and level indicator for demodulation (in addition to adjustable spectrum threshold detector)
  • stereo FM demodulator
  • low latency audio
  • frequency manager, groups and interactive markers, visualize, edit, navigate, tune the pass band
  • spectrum and waterfall popup menus
  • improved GUI controls
  • "fine tune" option: set pass band to rounded frequency (spectrum right click)
  • statistics visualization window

uSDR: A Lightweight Multimode SDR Receiver Program for Windows

Thank you to Viol Tailor for submitting news about the release of his general purpose multimode software defined radio receiver program for Windows called "uSDR" or "microSDR". Viol writes that uSDR is designed as a lightweight binary with a simple and compact user interface and highly optimized DSP to minimize CPU, hence the "micro" part of the name.

The software is compatible with RTL-SDR, Airspy, BladeRF, HackRF and LimeSDR radios. It has features including demodulation, base band and pass band recording, playback, and spectrum and waterfall visualizations.

Dump1090 with HackRF Windows Support

Thank you to Egor for writing in a sharing his work on modifying dump1090 in order to support the HackRF on Windows. dump1090 is software that is often used with RTL-SDR dongles for decoding ADS-B data for aircraft tracking. He writes:

Some time ago I was looking for dump1090 version with HackRF support that could work on Windows. But I have not found such version.
 
So I forked Malcolm Robb's version of dump1090 that could be built on Windows around 7 years ago. :) I've updated it and have added HackRF support from Ilker Temir's fork.
Now my version is available here https://github.com/esuldin/dump1090. The main difference from the others that it supports HackRF One device on Windows.

John’s Windows 10 NOAA Weather Satellite Software Guide for RTL-SDR

Thank you to John First for submitting his guide all about the setup and use of the software required to receive NOAA weather satellite images on Windows 10 (pdf file) with an RTL-SDR dongle. John's guide covers the use of SDR# for receiving the signal, WXtoIMG for decoding the signal, and Orbitron for tracking the satellite and automatically tuning SDR# when a satellite is in range.

He also explains the use of the VB-Audio Virtual Cable for piping audio between SDR# and WXtoIMG, as well as the DDE Tracking and Scheduling Plugin for interfacing SDR# with Orbitron, and finally how to do NTP clock synchronization to ensure the local time is accurate.

Standalone Windows FengYun-3 & MetOp HRPT Weather Satellite Decoder

Back in June we posted about Alan (@aang254)'s work on porting the GNU Radio gr-hrpt decoder over to GNU Radio 3.8. More recently Alan wrote in and wanted to share the news that he has recently released standalone Windows decoders for the MetOp and FengYun-3 weather satellites.

MetOp and FengYun-3 are both polar orbiting satellites that beam back high resolution weather satellite images. Unlike the NOAA polar orbiting satellites which transmit both the easy to receive APT and more advanced HRPT signal, these only transmit a HRPT signal at ~1.70 GHz, so a satellite dish and motorized tracking mount (or hand tracked) is required. You will also need an SDR capable of receiving over 3 MHz bandwidth such as an Airspy Mini or R2. Alan writes:

I recently got FengYun decoding working after the release of my MetOp decoder a while ago. Since gr-hrpt wasn't usable for Windows user without some major hassle, I made some standalone decoders (Windows builds included in the repo) for both MetOp and FengYun.

Decoding is done by first demodulating with the included flowcharts or @petermeteor's, then processed through the decoder which does Viterbi / Differential decoding. The output then needs to be deframed by MetFy3x or any other software that can do so.

DSD (Open Source) with dPMR Decoding and Windows Binaries Released

Digital Speech Decoder (DSD) is an open source program for decoding signals containing digital speech, such as DMR and P25. The open source version has been mostly surpassed in use over the last few years by the closed source DSD+ version. However, work is still ongoing on the open source version, and a recent fork by Louis-Erig HERVE @LouisErigHerve has added support for Digital Private Mobile Radio (dPMR) decoding.

dPMR is an open, non-proprietary trunked radio standard that supports both data and digital voice transmission. A licence free variation for short range communications called dPMR466 uses the 446.1–446.2 MHz band. Other modes allow for efficient peer to peer to peer operation (mode 1), operation with a base station repeater (mode 2), or with a trunking signal (mode 3).  All dPMR signals operate in FDMA mode with an efficient bandwidth of only 6.25 kHz. dPMR is also known as Icom IDAS and Kenwood NEXEDGE.

Code for Louis-Erig's DSD fork can be found on his GitHub, and he has also released binaries for Windows on his website. Over on his Twitter he has also been mentioning that he has been able to get around the basic privacy modes on DMR.
