MCU 1.68 / DSP 1.23, 9-24-2013

* LOW POWER (UNDER 1 W) NOW WORKS IN SSB MODE: Previously, with power settings under 1 W, SSB power output could drop to about 0.1 W and stay there.

* ESSB DISALLOWS USE OF CMP (compression): If the user attempts to adjust compression in ESSB mode, the VFO B display shows "N/A" (not available). The KX3's speech ompression algorithm requires the use of normal SSB bandwidths.

* DATA-A/AFSK-A/etc. BUG FIX: The MIC GAIN control now works as expected. In the previous release, adjustment of keyer speed while using the CW-in-SSB feature would leave the MIC GAIN control set to keyer speed when the user switched to an audio data mode.
