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:

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

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  , and on our Youtube Channel on

However, the two new videos can be viewed directly by going to: (New Features in SDRuno 1.3 – Scanning and AGC)   (SDRuno IQ output and CW Skimmer guide)

The ExtIO version of SDRuno can still be downloaded from our downloads page and is included in the SDRuno 1.22 release. Make sure to install it in a different directory to 1.3 otherwise it will stop 1.3 from working.
