While the use of the AuxBus connection is preferred for K3-KRC2
communications, it does not carry information needed by the KRC2ACC to
announce radio status. For this the KRC2 needs to be connected to the
radio using the serial port. To get full functionality from the
KRC2ACC here, which include radio change CW announcements, band
switching and ACC control from the radio, both serial port and AuxBus
need to be connected. And don't forget that the serial port needs to
be running at 4800 baud for all KRC2/KRC2ACC firmware versions prior
to V1.5.
The V1.5 firmware adds recognition of 6 meters from the K3, and new
microcontrollers from the factory have the bandmaps set to output the
6m selection on the XV1 pins. Users upgrading from earlier firmware
versions will need to use the configuration tool to remap their
bandmaps to enable this selection. Unfortunately there appears to be a
problem with the KRC2 configuration tool communicating with the KRC2
which currently prohibits this. We are investigating the problem and
potential fixes.
Anyone contemplating use of the KRC2 or KRC2ACC with their K3 should
download and read the KRC2 manual, revision C from the Elecraft
website, Manuals & Downloads page. It has a revised section on
connecting the KRC2 with various radios including the K3.

The KRC2 does not understand 6m, at least my version with the

I have just noticed the new firmware is now available for download.
Version
1.5. The KRC2 can now map 6m to 60m or 10m. This effectively means
you have
a choice of which HF band to work as 6m. To select this you need to
use an
invisible feature in the menu for the KRC2 on the K3. Press Button 1
(A/B,
1, B.SET) on the K3 to toggle 6m being mapped to 10m or 60m.
Note to Elecraft: Would it not have been lot more useful to equate
6m to one
of the ACC or XV lines?
