 #### SmartAudio V2.1 devices vary depending on their model. Check the manufacturers website.
 For these devices the `powervalues` are the output power in dBm.
 
+To query the available power levels from a SmartAudio 2.1 VTX enter the `vtx_info` command with no parameters. This will report the available power settings thus:
+
+```
+# vtx_info
+level 14 dBm, power 25 mW
+level 20 dBm, power 100 mW
+level 26 dBm, power 400 mW
