I don't see how adding another SWR bridge will help things.? The QMX already has a SWR bridge, it can also control the Tx power, and all this is under the control of the QMX controller.? All the OP is asking it it's possible to make the management of this more easily accessible.
I'm wondering if the SWR monitoring and power control can be used, ideally automatically, so the QMX provides the information we need to tune our antennas and also protects itself.
