mcu 3.19 / dsp 2.17, 6-14-2009
* power-related control lock: the pwr, mic, and cmp controls
can be locked by tapping Ƈ' 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.

k3原本就有分波段功率控制的功能，每个波段可以设置不同的功率输出，例如160m输出20w，10m输出100w等。这主要是考虑到有些功放达到满功率所需要的推动功率不同，有这个功能后切换波段就不需要再调整功率了。
大概一个半月前，我在论坛上发了一个帖子，希望提供功率、mic设置等的锁定功能，这样能最大限度地减少偶尔犯错导致很严重的后果，尤其是在多人参加的比赛中。
elecraft显然是在仔细倾听用户意见的，今天他们release了一个新版本提供了这个功能。
