Ok profiles may be used for:
Storing firmware option and fast change them ie when you have more two radios with different MB or options.
In profiles from general preferences can be stored also calibration setting of the radio.
Profiles can be used to patch eeprom while writing to the radio, ie you can start with a blank uncalibrated eeprom and calibrate it at write time.
The typical use is when you want to copy an eeprom from a radio to another. keeping programming but changing calibration.
While patching you can choose to patch calibration only or also hw related parameters.
Please have a look to the New feature post.
