The Portsdown 2020 build is primarily intended to be used with the LimeSDR Mini loaded with the custom LimeDVB Firmware. If you do not intend to use this new firmware it is not, at this stage (Feb 2020), worth switching to the Portsdown 2020 build - the more mature 2019 build could be better.

Background

The Raspberry Pi 3 has to work quite hard to drive a LimeSDR to transmit DVB-S and DVB-S2. In response to this, firmware has been developed for the LimeSDR that enables it to take on some of the processing load of generating QPSK and 8PSK modulation.
