MCU 2.80 / DSP 1.99, 1-23-2009

* AM POWER LEVEL NO LONGER DRIFTS: AM power setting is now more
accurate, and doesn’t change over time.

* AM TRANSMIT SIGNAL NO LONGER OVERMODULATED: AM ALC and
audio signal levels have been adjusted to provide a very clean transmit 
signal.

* DVR TERMINATION VIA PTT: Activating PTT will immediately stop DVR
transmit message playback.

* CWT (CW TUNING AID) ON/OFF STATE SAVED: If you turn CWT on, it will
always turn on when you return to the applicable mode (e.g. CW).

* MANUAL ATU L/C CHANGES ARE SAVED (per-band, per-antenna,
just like when doing an auto-tune). Manual ATU adjustment is possible 
when
CONFIG:KAT3 is set to LC SET (see owner’s manual). Previously, manual
L/C changes were lost when the KAT3 mode was returned to AUTO or BYP.

* ALC METERING AVAILABLE IN FM MODE: Previously, in FM mode the
ALC meter scale was fixed at 7 bars.

* CROSS-MODE SPLIT: When using cross-mode SPLIT (e.g. LSB/USB) with
the sub RX ON, the use of TUNE would sometimes result in an incorrect 
sub
receiver synthesizer frequency.

* SPOT and PITCH switches work correctly with switch feedback tones 
enabled.
Switch feedback tones are not used for these switches since a tone is 
generated
anyway. Previously, the sidetone would sometimes not be heard.

* XVx MENU ENTRY BEHAVIOR CORRECTED: Previously, adjusting these
menu entries would sometimes change the mode or frequency of the VFOs.

* VFO CTS MENU ENTRY: A change in the VFO counts-per-turn setting now
takes effect immediately, rather than requiring a mode change or power 
cycle.
