MCU 3.19 / DSP 2.17, 6-14-2009
* POWER-RELATED CONTROL LOCK: The PWR, MIC, and CMP controls
can be locked by tapping '1' in CONFIG:PWR_SET. This is useful in
some contests, such as Field Day, where a carefully-set up K3 might be
used by multiple operators. Accessing a locked control flashes "LOCKED".
SPD/DELAY/MON functions are still accessible. Tapping a locked knob
still
displays the current parameter value, even though you can't change it.
* AUTOMATIC CW VFO OFFSET ON MODE CHANGE: Allows switching
quickly between SSB and CW mode without either you or the other station
having to re-tune the VFO (often done on 6 meters and transverter
bands).
First, locate CONFIG:CW WGHT and tap ‘5’ on the keypad until you see
“VFO OFS”. From then on, when switching to CW mode from any other
mode, the VFO will be offset by an amount equal to your sidetone pitch
(as set using the PITCH switch in CW mode). If the sideband most
recently
used on this band is USB, the VFO will be shifted UP; if it was LSB, the
VFO will be shifted DOWN.
Note: If you make frequent use of this feature, you may want to
use CW reverse on bands where you use USB, and CW normal
on bands where you use LSB. This results in perfect pitch matching
when listening to a CW signal and switching from SSB to CW.
* GHZ TRANSVERTER DIGITS are now shown for two seconds on any
band change, if applicable (i.e. if transverter frequency is set for >
999
MHz in menu entry CONFIG:XVn RF). This serves as a reminder of
the actual band in use, since the MHz digits alone can be ambiguous.
* AM MODULATION: Now closer to 100%.
* TUNING VFO FROM ONE BAND TO ANOTHER WITH BANDS
MAPPED OUT: This no longer alters CONFIG:BND MAP settings.
* SYNTH UNLOCK WHEN USING PTT/CW: When using PTT, cancelling
CW message play by tapping the key or keyer was sometimes causing the
synthesizer to unlock.
* CW SIDETONE STUCK WITH PTT: When using PTT, cancelling CW
message play during a CW element was sometimes leaving sidetone on.
* 6M CAN BE PERMANENTLY DISABLED: This is required for some
countries. This would normally be done at the factory, but can also be
done in the field with a PC program (contact customer support if
interested).
* MAX POWER LEVEL NOW 110 W (was 120 W): This is intended
to reduce the possibility of excess KPA3 operating current on some
bands. This might have occurred when using a high power setting
along with low power supply voltage and/or a high load SWR.
(Note: The recommended maximum power setting is still 100 W.)
For Software Developers:
* MONITOR LEVEL (ML) COMMAND: MLxxx (000-060 where 000 is
OFF, in effect). Applied per-mode.
* IC COMMAND NOW HAS A "TX MSG PLAYING" FLAG. Byte "a" bit B2.
