See KAT500 Firmware Release Notes for a complete revision history.

This firmware version has new features configurable only in KAT500 Utility 1.13.2.13 or newer. See downloads below.

• New Feature: Memory Recall Tune (in-band QSY). When the KAT500 detects drive on a frequency within the same band, but in a different band segment, it will recall settings previously stored for that segment. This feature defaults ON in mode MAN and mode AUTO, but may be disabled via KAT500 Utility. In Utility, select Configuration, Edit Configuration, Tune on QSY. Utility version 1.13.2.13 or later is required to access this menu.

• Perform "memory recall tune" on in-band QSY on Tx frequency count in Mode MAN, without regard to VSWR.

• Perform "memory recall tune" on in-band QSY on Tx frequency count in Mode AUTO, without regard to VSWR, followed by a "full search" tune if needed to reach Autotune VSWR threshold.

• Add MTA and MTM commands to permit owner to enable or disable memory recall tune on in-band QSY. See KAT500 serial command reference. KAT500 Utility configuration support for this command is in KAT500 Utility version 1.13.2.13 and later, Configuration Tab, Edit Configuration, Tune on QSY tab.

• Change minimum "start tune" power to 7 watts. Some ICOM radios produce just under 10 watts when their TUNE button is pressed. Matches will often improve if higher power (20 watts) is used.

• Reduce full search time when starting on "nearby" frequency.

• Clear fault on all button presses, antenna change, band change.

• Generate fault when transmit power is too high (over 100W) with amplifier key line interrupted.

• Add optional frequency to SM command to permit saving tuner settings without having to transmit on that frequency. See new KAT500 Serial Command Reference for detailed syntax.

• Added FLTC; serial command to clear current fault.

• Issue FT; response when tune completes and exciter tune power is no longer needed.

• Add PS; and PS1; serial commands to query and turn on power.
