KX3 production firmware rev 1.79 (with DSP rev 1.27) is now available. Since
the last production firmware release (1.61), we've made the following
improvements:
* Full support for KXPA100 amp and KXAT100 ATU
* More accurate power output control in SSB mode for settings under 2 W
* Lower-distortion FM receive
* FM transmit deviation max now 6 kHz (was 5 kHz)
* Added DTMF tone generation (FM Mode only) using numeric keys
* DATA-A/AFSK-A mode bug fix: MIC GAIN control now works as specified.
In earlier releases, adjustment of keyer speed while using the CW-in-SSB
feature would leave the MIC GAIN control set to keyer speed
even when the user switched to an audio data mode.
**************
IMPORTANT NOTE
**************
You'll need the *most recent* version of our KX3 Utility application to
download and install the new KX3 firmware. Older versions of KX3 Utility may
not load the KX3's DSP firmware correctly, due to increased flash memory
requirements.
For instructions on obtaining KX3 Utility, see:

Production firmware releases are automatically downloaded from our FTP server
when you click "Copy Files from Elecraft" from within KX3 Utility.
