SNR 
Signal-to-Noise ratio 
It shows you the ratio between the received noise and your Crossfire signal. 
To judge RSSI properly you need to know the SNR and compare it with your RSSI value. The Crossfire can 
receive signals in the noise down to -6dB.  
Excample: 
A RSSI of -80dBm is fine. But with a SNR of -2dBm it's really bad. 
Positive numbers mean the Crossfire signal is "louder" than the noise,  
negative Numbers mean the noise is louder than the Crossfire

What should i use in my OSD or radio 
The easiest way to set up your OSD or radio warning is by ​ u sing LQ​ . It is linear which makes it easier to 
monitor for most of the people, while RSSI got a logarithmic scaling which makes it drop rapidly at the 
beginning and then slower the further you go.
