ExtIO_RTLSDR# – Modified ExtIO for SDRUno/HDSDR with Direct Sampling Mode

Fixed RTL-SDR EXTIO for SDRUno.
Fixed RTL-SDR EXTIO for SDRUno.

Over on our forums user qrp has released a modified ExtIO that allows the direct sampling mode to work correctly in SDRUno. SDRUno is SDRplay's official software for their RSP line of software defined radios, but SDRUno can also work with ExtIO input dlls which allow other SDRs like the RTL-SDR to be used.

The commonly found RTL-SDR ExtIO however doesn't seem to work properly with direct sampling mode in SDRUno, so HF on RTL-SDR Blog V3 or other direct sampling modified RTL-SDR dongles is inaccessible. The new ExtIO fixes the direct sampling problem, and also enables a Remove DC algorithm to remove that center spike, which isn't an option in SDRUno.

To use the ExtIO simply extract the ExtIO_RTLSDR_u8.dll and rtlsdr.dll files from the zip file into a folder on your PC. Then from the Start Menu find the SDRUno (EXTIO) shortcut and run it. When it asks you, select the ExtIO_RTLSDR_u8.dll file. Note that you will probably need to use the older v1.22 SDRUno version as V1.31 doesn't appear to have an ExtIO version.

SDRPlay Hamvention Demo of SDRUno and RSPDuo Diversity Features

At this years Hamvention Chris Howard from ICQ Amateur interviewed Andy at the SDRplay booth. In the interview they discuss various new features and improvements to SDRuno, the official software for SDRplay devices.

Later they also discuss the RSPduo, and the new diversity feature coming in a new version of SDRUno that is due to be released in a few weeks. The diversity feature works with the two tuners on the RSPduo to combine or subtract signals from two different antennas. Andy notes that diversity should be able to achieve a net 3dB increase in SNR, and is most useful for a moving or dynamic signal environment.

Finally Andy discusses the future development of SDRUno and notes that they're working on a plugin environment which will allow the creation of third party demod/decoders, a multiplatform server for remote SDR, and eventually cross platform drivers and SDRUno.

SDRPlay Announce Update to SDRUno and Future Plans for Software Defined Radio at Hamvention 2019

SDRplay Release SDRUno V1.3 – Now with Frequency Scanning Feature

SDRplay have just released a major upgrade to SDRUno, the official software for SDRplay RSP software defined radios. Along with various bug fixes, the most interesting new feature in version 1.3 is the frequency scanner. This allows SDRuno to automatically tune to active signals between a set frequency range. SDRplay writes:

Major new features include:

Frequency Scanning (for both frequency ranges and stored memory panel lists)

I/Q → Audio Output (for CW Skimmer for example)

A new configurable IF AGC scheme

For a full list of additions/changes and bug fixes, please see the release notes at: https://www.sdrplay.com/docs/SDRplay_SDRuno_Release_Notes.pdf

This release of SDRuno uses a new version of the Windows Service based API (3.02) and so users that also used other applications such as dump1090 and HDSDR with the previous version of the Windows Service based API (3.01) will need to download and install the latest versions of API, dump1090 and the ExtIO plugin from our website at https://www.sdrplay.com/downloads

We have produced two new video guides which describe the use of the Frequency Scanner and I/Q Output functions. Links to these videos along with many others can be found by going to the SDRplay Applications and support catalogue on https://www.sdrplay.com/apps-catalogue/  , and on our Youtube Channel on https://www.youtube.com/c/SDRplayRSP

However, the two new videos can be viewed directly by going to:

New Features in SDRuno 1.3: Scanning and AGC

SDRuno Updated to Version 1.22

The official software package of the SDRplay range of products is SDRuno and it has recently been updated to version 1.22. SDRuno is also compatible with the RTL-SDR.

In addition to some UI improvements for new users, the main changes are pasted below. What's also very interesting is their road map which states that future versions of SDRuno will have frequency scanning capabilities, a remote network streaming server/client implementation and an API for the support of third party plugins. This would improve it's capabilities similar to that of SDR#.

Added
• Support for 1366×768 default layout
• ADC overload detection in AGC off mode
• ADC overload acknowledgment system to avoid lockout condition
• Custom step size for each mode
• Band Button Groups (Ham Lower, Ham Upper, Broadcast)
• Two additional SP1 width presets (2560 and 3840)
• Additional menu option in memory panel to reset column widths (helps when upgrading)
• Scheduled Recording
• Auto update

Changed
• Registry reset now only clears 1.2+ entries
• SP1 Window max size supports 4K displays (3840×2160)
• Small improvements to the memory panel (panel width and field width changes)
• Improvements to the IF output mode
• UTC time fixed to 24 hour format
• Play!/Stop button colour coordinated
• Move MUTE button to make way for VOLUME label
• Moved Squelch value display to the right

Fixed
• Log10 SING error
• Aero support detection to try to prevent rendering issues
• Freezing when switching to HiZ port in gain mode
• Gain “pumping” issue when in gain mode
• Settings panels not displaying properly when “un-minimised”
• Zoomed in frequency scale drag out of bounds bug
• Noise floor measurement bug
• Improved RSP error handling
• Sample rate change causing spectrum display issues
• Device selection bug

Known Issues
• SP2 CWAFC drift issue (Zoom/window size/freq display) – will be addressed in 1.23, workaround for now is to zoom out fully in the SP2 window and then the CWAFC feature will work.
• IF output mode disabled SP1 spectrum mouse clicks – temporary issue until LO is separated from the VFO (see plans below)

Following on from the 1.21 release where we outlined the features for coming releases, we have updated our plans, as shown below. The purpose of publishing this information is to give people an insight to the development plans but it is NOT a guarantee of the exact feature line-up and we cannot give release dates.

1.23 Intermediate update
• Recording of selected signal only (either I/Q or audio) to WAV file format
• Selected signal piped to VAC in I/Q format

1.3 Major update
• Separation of VFO and LO frequency control
• Frequency scanning

1.31 Intermediate update
• Remote client for network based streaming I/Q server applications

1.4 Major update
• Addition of new API for third party plugins

SDRuno v1.22 Improved UI
SDRuno v1.22 Improved UI

UPDATE: Mike Ladd from SDRplay has uploaded a video showing what's in the new version.

SDRuno What changed in v1.22

Using the SDRuno EXTIO Edition with an RTL-SDR and other SDRs

Over on YouTube Mike from the SDRplay team has created a tutorial video that shows how to use the SDRuno EXTIO edition. SDRuno is the official software of the SDRplay line of products and can be freely downloaded from the SDRplay website. The EXTIO edition allows other non-SDRplay SDR units to freely be used with SDRuno. The only restrictions are that the maximum bandwidth is artificially restricted to 2.5 MHz and some DSP filters are missing.

In the video Mike shows how to set up the SDRuno workspace to work with an RTL-SDR dongle and demos reception of some signals. Note that the EXTIO dll file for the RTL-SDR mentioned in the video is the same one required for HDSDR, and can be downloaded from the dll table on the HDSDR website.

If you’re interested in more, Mike has a full SDRuno tutorial series available on the SDRplay YouTube channel which mostly focuses on usage with the SDRplay units, but could be applicable to the EXTIO version as well.

Mike’s SDRuno Tutorial Series

Mike Ladd, one of the top volunteer contributors of the SDRplay community was recently hired by SDRplay officially and has now been working on a fairly comprehensive SDRuno tutorial series over on the SDRplay YouTube channel. SDRuno is the official software for the SDRplay line of SDRs and is a slightly modified version of the ‘Studio1’ software which was previously acquired by SDRplay. SDRuno also supports the RTL-SDR.

SDRuno is a complex piece of software with many features and settings, so it’s great to see a comprehensive video tutorial like this. Mike’s tutorial series currently has 10 episodes, and discusses things like the basic layout and settings of SDRuno, using Virtual Audio Cable (VAC), noise reduction, memories, calibration, DSD, notch filters and FM broadcast with RDS. More videos are probably still on the way.

SDRuno Updated to V1.1: Now supports up to 2.4 MSPS for the RTL-SDR

SDRuno is the official software for the SDRplay RSP software defined radio. Recently they’ve released version 1.1 which contains various new features and bug fixes for the RSP. The SDRuno Cookbook by NN4F & KD2KOG has also accordingly be updated with information about the new features.

In addition they’ve also now increased the previous 0.96 MSPS sample rate limit which was enforced for all third party radios running via EXTIO drivers. The new limit is 2.5 MSPS (with 2.4 MSPS being the limit for the RTL-SDR). This is great news for RTL-SDR users as SDRuno for the RTL-SDR is now almost as functional as in other SDR software like SDR#, HDSDR and SDR-Console. The change log is pasted below:
