SDR++ Recent Updates: Plugins, Multi-VFO, Multi-Platform, Native RTL-SDR and More!

Back in July 2020 we first posted about the alpha release of "SDR++" which back then was a new project by "Whatsthegeek" that was determined to bring an open source, cross platform, C++ based GUI general receiver program for various SDRs including the RTL-SDR to the community. Over the past few months the author has been working hard on updating the software, and it's looking a lot more mature today. Recently he has released the following updates as mentioned on his Reddit post:

As some of you might remember, I posted back in june about my SDR++ project. During the past 6 months, I've been hard at work to make it into usable software! The versions I released in june and july were extremely buggy and unusable. All of those issues have now been fixed. It's now simple to build and install. Here's a small rundown of the features it now has:

• Fully modular architecture (plugins)
• Multi-VFO
• Support for most SDRs through dedicated modules or SoapySDR
• Both baseband and audio recording with a level meter and volume adjust
• Multiple bandplans available (very easy to write your own)
• Switchable waterall colormap
• Low CPU usage (lower than GQRX, CubicSDR, SDRConsole and in some cases SDR#)
• Full waterfall update when zooming or changing min/max level

Also, SDR++ now runs on Windows, Linux, OSX and BSD!
Do note that it still has a few quirks and misses some features (see https://github.com/AlexandreRouma/SDRPlusPlus/projects/2 for the todo list)
In addition to what's in the todo list, decoders for common satellites will be written very soon. They will allow decoding of Meteor and NOAA with no external software needed!

I'd like to thank Airspy, Analog Devices, SDRplay and Howard Su for sending samples of their hardware for development! Would never have been able to add support for their hardware without it!

I hope this software will be useful to the community :)

Releases for Debian Linux and Windows can be found over on the GitHub Releases page. 

We note that over on Twitter Whatsthegeek (@ryzerth) has been releasing further updates. He notes that some of the latest code updates for SDR++ add a native RTL-SDR module including bias tee support, and that it is also now available as a package for Arch Linux users over on the user Repository. However these latest updates are not yet available as binaries on the releases page.

In a recent tweet he also demonstrates the very useful looking multi-vfo feature allowing him to decode three AERO signals with Jaero simultaneously on a single RTL-SDR dongle.
