Warbird asks " may i ask what the Q and A means. i have the 24 . i just got it but haven't dove into it yet . "i'm try to focus my attention on completing my jet before i get into the programming""
Here is how I understand it. There may be some fuzziness in the details, but it's a good way to think about it, well for me atleast!
Q value- This is a value that your tx interprets how "clean" the telemetry signal is. This is a measure of how your receiver is transmitting to your transmitter. It ranges from 0-99 and numbers (I've heard) from 20-50+ are OK. (I will be crucified here, but, oh well)
A value- This IS THE most important number to look at. It ranges from 0-9. This number evaluates how well your receiver is receiving the signal from the TX.
It is not clear how to make them pop up on your home screen, or which value to have an alarm. You would think that these things would show up automatically and they would be something you'd like to turn off instead of on, because, hey isn't how well our tx is talking to our rx REALLY, REALLY what we care about?
It is my understanding that you will lose the Q values at over twice the distance you'd lose your A values.
Again, this is my understanding. It maybe technically wrong in some senses, but it is a good "working" knowledge type of position.
