Portsdown 2019 Interconnects

[G1BVI]

There is a very clear Interconnect drawing in the Portsdown 2018 area:-

I cannot locate the new Portsdown 2019 interconnect diagram.
Does it exist?


The reason I was looking for this is that the system diagram of the Portsdown 2019 shows RPI GPIO outputs selecting the bands on the band decoderto illuminate the LEDSand from that board to provide correct RF port switching.
It also shows a connection from the Lime SDR to this board.

My understanding was that the RPI GPIO OR the Lime SDR FPGA pins could be used to control the band switching.

Additionally the wikki suggests NOT using the lime SDR pins for band control.

The diagram also shows a wire labeled PTT from the GPIO but this is labeled TX on my GPIO output board and my Four port Indicator.


This may perhaps give confusion to some builders.
