Dual Receiver Panda

Hardware
1

I am using v2 arduino steer boards with separate Panda boards (f9p + BNO085) in my tractors. I want to try a dual receiver setup to see if that improves performance.

My understanding is that the v2.5 teensy board can do dual receiver like the v4 boards, so I could connect a second f9p instead of using a BNO to try it.

Does anyone have a schematic or wiring diagram for the v2.5 board or for a stand alone dual antenna using a teensy?
Is the circuit the same for the f9p receivers on the v2.5 and v4 boards?

This is what I have come up with so far from looking at the gerber files for the v2.5 board and adapting the panda diagram to suit.

Can anyone see any reason this shouldn’t work?
Is the circuit for the TX2 on the right receiver only needed if using radio for rtk instead of ntrip?

I built one like this last summer and it sort of worked, but something wasn’t right with it and it never got rtk fix.
