At the end of last year, I announced the “proof” that Software Defined Radios also can have buttons and knobs. At that stage, the software was still a prototype and not ready for a public release. In the meantime, I was working hard to eliminate bugs and implement further improvements. By today I’m happy to announce the release of the PowerSDR-UI beta. This is a call for beta testing. Please feel free to download the software and participate in the beta testing phase!
