A few comments about the WBX boards:
They are half-duplex. I.e., transmit and receive are mutually exclusive.
There is a single LO for both the Tx and Rx sides.
The the shared control signals are hung off of the Rx side.
The shared io controls are duplexed onto the Rx side pins.
The wbx_high d'board always needs to be in 'auto_tr_mode'
