Many high-power tuners, including the KAT500, work best with 10-20 W of RF. You can now use the KXPA100 in this range, since it is more tolerant of the forward- and reflected-power overshoots that often occur during antenna tuning.

Thanks for the update Wayne. On the firmware page it says, "This version of firmware has new features that require the very latest KXPA100 Utility.". However, the Mac OSX version of the utility is still dated 16 Nov 2013. Is it ok to use the OSX version of the KXPA utility, or must we use the Windows version (dd 4 Mar 2014) if we want to try the 1.25 beta?
