[Elecraft] KXPA100 firmware rev 1.25 now available -- works well with external antenna tuners

[Wayne Burdick]

The latest KXPA100 beta firmware, rev. 1.25, significant improves the amplifier's behavior when used with external antenna tuners. 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.

There's another notable improvement: When the attenuator is inserted because of SWR or high reflected power, it will be released immediately on the next key up if SWR has been reduced to 3:1 or better. 

Please refer to our KXPA100 firmware page for further details:
