Excellent job, Wayne!
SUB/MAIN ballance and easy ANT switching is really big improvement!
Many thanks,
Lexa, ok1dst
with still growing K3/10 :-)

* MAIN/SUB BALANCE CONTROL: If CONFIG:SUB AF is set to BALANCE,
then the SUB AF GAIN control becomes a main/sub AF balance control when
the sub receiver is turned on (including diversity mode). In this case
the MAIN
AF GAIN controls the AF gain level for both receivers. When SUB AF is at
12 o’ clock, both receivers will be at full volume (main left, sub
right). If SUB AF
is rotated fully counter-clockwise, you’ll hear only the main receiver.
If it’s
rotated fully clockwise, you’ll hear only the sub receiver. At
intermediate settings
you’ll hear both. A BALANCE control is very useful for contesting and split
operation. But it can also save a lot of AF gain control tweaking (i.e.,
matching
main and sub), since MAIN AF controls both main and sub receiver audio.
* AGC-OFF AF LIMITER: An adjustable AF output limiter has been added
for operators who turn AGC off. This can protect your ears if a large
signal
appears. Signals or noise above the threshold will sound highly distorted
due to the limiting action, reminding you to back down the AF or RF gain.
The associated menu entry, CONFIG:AF LIM, defaults to NOR. Typical
settings for those who often turn AGC off are 17 to 23, but some
experimentation
will be required.
* EASY SUB RX ANTENNA SWITCHING: A hold of RX ANT will alternate
between MAIN and AUX for the sub receiver’s antenna, if the sub is
installed.
This is faster than going into BSET to switch the sub antenna.
* SUB ANT SAVED SEPARATELY FOR DIVERSITY/NON-DIVERSITY:
At many stations, the sub receiver’s AUX antenna is only used in diversity
mode. The K3 now remembers which sub RX antenna setting you use
in diversity and non-diversity cases, so you won’t have to use BSET as
often.
* DIGOUT0 SIGNAL (ACC connector): This now behaves as described in the
owner's manual. When a transverter band is selected that is configured for
low-power operation (i.e., .01-1.50 mW, and using the KXV3’s XVTR IN/OUT
jacks), DIGOUT0 provides a low-resistance path to ground that could be
used to
activate a small relay or other circuitry. At all other times the
DIGOUT0 line
will float (high-Z). If all transverter bands are configured for low
power, then
DIGOUT0 can be used as a “transverter band selected” signal.
* POWER LEVEL ON XVTR AND HF BANDS: Switching between HF and
transverter bands no longer modifies the present HF band power setting.
