Hi Andi,
There is no calibration for the SWR/PWR meter per band.? If you were to calibrate for 10 meters, then 80 meters would most likely be off.? I believe that most sbitx power measurements are off.? That is the case for my V3.? I use it as a relative measure to verify that the output stages are OK.? I believe it is possible to improve the accuracy with circuit changes, like adding a Faraday shield to the center wire of the SWR/PWR sensors.? This has been done for other radios with the same type of sensor.
Reference info on the sensor:
If higher accuracy is important to you, you could add the code to adjust the scaling for each band.? That is what is done for the drive values.? AFAIK that is not on anyone's list of coding modifications.
