title_body: Does the Meteor65 Acro support Spektrum RSSI?
upvoted_answer: Most serial receivers support RSSI through a feature called RSSI channel.
  
  This means, unlike in receivers with a dedicated RSSI output, you can map one of the channels to carry the RSSI signal.
  
  For example, on a FrSKY receiver, the telemetry channel is channel 16, or aux 12.
  
  So you would go into the receiver tab in Betaflight and set RSSI channel to aux 12, and then place the RSSI icon in the OSD.
  
  It is likely a similar process for Spektrum, so I would recommend consulting your transmitter’s manual.
