This will use the Raspios Buster (NOT Raspbian) operating system on a Raspberry Pi 4 with a 7 inch screen and a LimeSDR. Unlike the previous version changes it will not maintain hardware compatibility with the classic (filter-modulator) Portsdown.
You may have seen mention of the Portsdown A27 – this version was the stepping stone from the Portsdown Buster 2020 to the Portsdown 4, and will not be continued after the release of Portsdown 4. First development release of the Portsdown 4 should be during July or August 2020.
