What is the ''certain dynamic condition''? Making a claim like that is akin to me saying the same thing about Faast, and when you ask what the condition is I state ''when soaked in kero for 3 hours, placed in a centrifuge and then lit on fire with a torch''.
RF Noise from sources like electric motors and static buildup.
From the Device Datasheet:
Datasheet Document #: 38-16015 Rev. *I on page 23 refers to L/D pin recommendation changed to :
"PMU inductor/diode connection, when used. If not used, connect to GND.
From Cypress technical support:
If the L/D pin is left floating, the switching regulator inside the PMU will pick up noise which will in turn increase the radio noise and the noise on the board.
PMU refers to Power Management Unit. It is a feature to prevent brownouts. Spektrum did not implement this feature and this pin was left unconnected.
This is a cut and dried technical issue confirmed by die chip vendor. Not debatable, sorry
