Do the transmitter and receiver powers have to be matched, I.e. Is it ok to have a receiver with a higher power spec than the transmitter? What should the aim of matching be?
Are you talking about FPV transmitters/ and recievers or telemetry or R/C?
Generally speaking the power levels will not matter if they are not matched, but most important is that the frequencies match. We have more information in our FPV transmitter guide
Thank you, now understand!
