The Portsdown 4 system has been specifically designed to be used with the Raspberry Pi 4 and the official Raspberry Pi 7 inch touchscreen. No other models of Raspberry Pi or touchscreen are planned to be supported in the near future so please don't ask.
The Portsdown 4 has the following capabilities:
- DVB-S and DVB-S2 (MPEG-2 and H264) transmissions from a LimeSDR Mini connected by USB
- DVB-S and DVB-S2 (H264 only) transmissions from a Pluto SDR connected by USB
- DVB-S (MPEG-2 and H264) transmissions from a DATV Express Board connected by USB
- Supported video sources include the Raspberry Pi Camera, C920 WebCam or a USB-connected EasyCap composite video capture device
- Reception and display of DVB-S and DVB-S2 (MPEG-2, H264 and H265) signals received by a BATC MiniTiouner Mk 2 connected by USB.
The Portsdown 4 does not support the BATC Filter-modulator board or Ugly mode.
The software build is also compatible with the Langstone Microwave transceiver software, which can be loaded by from touchscreen selections (menu 2) AFTER the Portsdown software has been installed. To operate, the Langstone software needs a Pluto to be connected by USB, and a compatible USB Audio dongle.
You MUST start with a fresh build of Raspios Buster (NOT Raspbian) on an SD Card of 8 GB or greater, so you will need to rebuild any previous Langstone or Portsdown A27 card.
