I am playing around with my RF signal meter, but the manual does not elaborate at all on what any of the signal levels returned actually mean:





PWR is POWER, or, essentially signal-strength.
BER is Bit-Error-Ratio.
MER is Modulation-Error-Ratio.

What is CN?   ...and don't say "China"!  
If it was "SN:" I would think it was Signal-Noise ratio, but "CN".....
Channel-Noise?
...but that could not be right, as 96% noise on that channel would surely be something you would not want!  
Smoke makes things work. When the smoke gets out, it stops!
