I have not done the diff yet on the firmware but I highly doubt any difference is there. Hardware design is the same and the software supports high power settings. The eeprom values will be different ofcourse. But thats not firmware?

Is there any software differences betwern ATU-100 and ATU-1000? I don't think it is. Only different windings on the SWR bridge and more heavy duty toroids and perhaps relays. At least that is how I understand it.
