Future Releases:

  • Timed recordings
  • Rig Control
  • Module Support

System Requirements:

SDRconnect runs on the following architectures:

x64, ARM64 (including Apple Silicon)

Please NOTE. SDRconnect is a 64-bit application and will NOT run on 32-bit operating systems.

Supported Operating systems:

Windows – 10, 11 and later – 64-bit only. Note SDRconnect will NOT run on anything earlier than Windows 10, so please don’t ask for Windows 8/7/XP etc. It is not possible to compile for these older operating systems with the tools used for the development of SDRconnect.

Linux x64 – Canonical Ubuntu 22.04LTS and later LTS releases *

Linux ARM64 (aarch64) – Raspberry Pi OS (64bit) – Bullseye derived (we recommend the Raspberry Pi 4B or better)

MacOS x64 – 10.15 (Catalina) and onwards

MacOS ARM64 (Apple Silicon) – 13.0 (Ventura) and onwards

* You may well find that SDRconnect will install and run on other distributions of Linux, these are just the supported ones.

 SDRconnect and SDRuno are able to co-exist on the same OS – Please note: This requires the latest version of SDRuno to be installed.

SDRuno plugins will not work with SDRconnect, but we will be porting the SDRplay developed SDRuno plugins so that they will be made available for use with SDRconnect as modules. The module interface will be published so that third party developers can also port their SDRuno plugins to SDRconnect modules, but we have no control over whether they will choose to do so, so please contact the plugin developers about this.


This is the latest version of SDRconnect, it includes the server software for installing on a remote device.

Release notes for all versions of SDRconnect can be found here (

We believe this software is stable on all supported platforms. However, each release is another step in the long term development of a relatively new platform and future releases and modules will further enhance functionality.

WE ARE NOT PROVIDING SUPPORT FOR THIS PREVIEW SOFTWARE VIA OUR TICKET SYSTEM. You can report any bugs that you find be emailing:    [email protected] – ONLY if you are using one of the supported platforms listed above. Please note that we will read any feedback sent to us, but we will only respond to you if we require further information.
