How are your antennas setup and how are you calling set_auto_tr() and
set_enable()? Note that tx and rx paths each have their own set of ATR
registers that can be configured independently. For the first case,
assuming that both ATR masks are enabled for the RFX, the receive
mixer will be disabled while transmitting. For the second case, both
paths are enabled, which should explain the observed behaviour.
