Gabriel,
The receivers send information to the transmitter everytime they receive an information package. In other words, there is an acknowledgment of package received.
The transmitter counts the number of acknowledgments that it "heard" and compares it with the number of packages sent. Q represents that percentage.
Q = 100% means all packages sent were received, with no doubt.
Q < 100% could either mean that the packages were not received; or, that the acknowledgement was not "heard" by the transmitter.
The important values to monitor are the A's. They represent the volume or intensity of the signal received.
Q related alarms are annoying and useless in my opinion. Alarms for a low value of "A" (say 3) are great information.
