Changes:
 
- ATU TUNE low-power threshold was adjusted so that ATU tuning doesn’t get stuck if the KX3's power output folds back (reduced due to SWR or high current). In prior versions, the KXAT100 would not start a full-search tune at less than 1.8 watts, and if power dipped below 1.5 watts during tune, tune would stop, waiting for more drive power. In the current version the KXAT100 starts and continues full search tune at any detectable power over 250 mW. Its assumes that if the drive power is too low to compute SWR, then the SWR must be bad here, and we progress in the tune search algorithm. This is how the KAT3 and KXAT3 ATUs work.
 
- Input power threshold was adjusted to reduce the incidents of faults during tuning.
 
- Band voltage tables for IC-703 and Yaesu FT-817 were updated. This was necessitated by hardware changes since initial measurements were made with an earlier prototype.
