[Elecraft] KXPA100 f/w 1.28 now production released

[Eric Swartz - WA6HHQ, Elecraft]

KXPA100 Production Firmware MCU 1.28 has been released to production status and 
is now shipping.

Important: This version of firmware has new features that require the very 
latest KXPA100 Utility.

We recommend all KXPA100 owners upgrade to the latest KXPA100 utility and to 
KXPA100 MCU 1.28.


Some of the Key Changes in this release:

- Better tolerates forward and reflected power overshoot for brief periods to 
support external antenna tuners. Use approximately 10-20 watts of KXPA100 output 
when tuning.

- When the attenuator is acquired because of SWR or high reflected power, 
release attenuator immediately on next key up if SWR has been reduced to 3:1 or 
less.

- Update band voltage tables for ICOM 703 and Yaesu FT-817

- Reduce power required for ATU tune.

- Add per-band Antenna configuration (requires the new KXPA Utility for user 
interface)

- Improved RS232 handling for 3rd party applications. (Ham Radio Deluxe v6.2, 
PigKnob, etc.)
