We are pleased to announce the release of v1.32 of SDRuno. The purpose of this release is primarily to add MRC Diversity functionality for the RSPduo, but it also contains other fixes and additions based on customer feedback. Diversity functionality is described on P.78 of the SDRuno User Manual.
Each year at the Dayton Hamvention I enjoy checking out the latest radio products and services. This year (2019) I found an exceptional number of innovations and will share these in Hamvention Highlights posts.

At the time, SDRplay mentioned that the RSPduo could eventually be used for diversity reception.
Diversity reception is the ability to combine or select two signals, from two (or more) antenna sources, that have been modulated with identical information-bearing signals, but which may vary in their fading/noise characteristics at any given instant.
In short, diversity reception gives one a powerful tool to mitigate fading and noise, and to improve a signal’s overall integrity.
Andy and Mike with SDRplay demonstrated SDRuno’s diversity reception functionality and noted that it will soon roll out as a free upgrade to SDRuno, SDRplay’s open SDR application.
I should note here that the SDRplay booth at the 2019 Hamvention was incredibly busy—no doubt, because the RSPduo must be one of the least expensive, most accessible, ways to experiment with diversity reception. Case in point: the new Elecraft K4D transceiver will support diversity reception, but the price is about $4,700 US; the RSPduo can be purchased for $280 US.
Based on the demonstration, this feature will be quite easy to use and I love how it has been implemented in the SDRuno GUI (graphical user interface).
To learn more about the RSPduo, check out SDRplay’s website or read our review. Of course, when SDRplay releases the diversity reception upgrade to SDRuno, we will make an announcement!
Many thanks to Dennis at Bonito, who notes that he has just tested the SDRplay RSPduo on two of Bonito’s high-performance antennas: the MegaLoop FX and the new MegaDipol MD300DX. Bonito posted a detailed article about this on their website.
We are pleased to announce the release of the ExtIO plugin for the RSPduo. This release uses the latest API (v3.01) which is also being updated today. The plugin will work both in single tuner as well as dual tuner mode so multiple applications can use the same RSPduo at the same time.
The plugin installer will automatically install the Windows 3.01 API so there is no need to install it separately.
It will put the ExtIO dll into a default directory (usually C:\Program Files (x86)\SDRplay) and then you should copy that into your application install directory (e.g. C:\Program Files (x86)\HDSDR)
In order to improve the interoperability between this plugin, SDRuno and dump1090, both of those applications have been updated as well. There have been no other functional changes to those applications.
