Yes. You are correct. Calibration values are stored in EEPROM. Updating HFsignals firmware will not change these settings. Ian's firmware also uses the same calibration addresses (although he has added more to the memory map)
...I fear I may have inadvertently sparked a question based on one of the posts I made today. I had ported the firmware to an ARM core that does not have EEPROM.? Sorry if this caused confusion.
