Hi all.

I found that both Rx divercity switches have zero state for A and B control
inputs.
Thus both LNA and LNA-D connectors are not switched to Rx inputs of the
LMS's.
To proceed Rx testing I suggest to set the next fixed states in the FPGA:
DIVSW1_P = 1,  DIVSW1_N = 0,  DIVSW2_P = 1,  DIVSW2_N = 0.
In this case LMS1 will be switched to LNA connector, but LMS2 to LNA-D.

Andrew Karpenkov, would you please to make this kind changes, until DIVSW
will controled by host?

Best regards,
Andrey Sviyazov.
