We are close to releasing the PR6-10. (Same case as the PR-10.)
Assembled PCBs are in-house and we need to test them and release the
manual. I'll post here when its ready for taking orders.

I don't know about that ... the incremental cost for the KXV3A
vs. KXV3 was minimal. The firmware changes to support two more
control lines should be minimal.
As far as an internal preamp - it should not be significantly more
complex than the PR6. With switching on a "KVX3B", an internal
preamp would not need the bypass relays so they could be used for
band switching if needed. However, if the user did not want a
10/12 preamp, it would not be a stretch to use the existing PR6
internally for six meters only.
One would think it relatively straightforward to switch two input
tuning/matching networks in a PR6 style preamp or an alternate,
broadband design could be used to completely avoid the need for
band switching. With a little care in the design and programming,
a higher gain/lower nf preamp could be substituted (electronically)
for the standard preamp or the controls could be arranged to cycle
through "none"/"norm"/"opt".

I'm not saying it isn't possible ... takes one additional relay
and two connectors. There are even couple unused control lines
on the KXV3A that could be used to control the added relay and
switch bands (10/12 and 6 M) if necessary.

I agree that an internal preamp (or premps) would be ideal.
However,
in addition to the preamp(s) Elecraft would need to provide
*another*
design for the KXV3A - one that switches the RX ANT IN/OUT
connections
to internal jacks - as neither the original KXV3 or current KXV3A
have
that capability.

So what if a K3 needs to NOT have a 2M transverter to fit a combo

This
is a
choice made by the original owner I guess which is what it is, a
choice. I
fully appreciate everyone's point of view, but I would hazard a
guess I
am
not alone in wanting an internal unit as a CHOICE, not at the
expense of
taking away other folks right to choose.
Wayne has stated Elecraft's case and that is there is not enough
room
but
his statement is qualified by the mention of the 2M option which
is a
customer choice right?

You mention remote install, fine, but again it is still another
cable
and
still yet another box to cart around. Setup on a table (standard
picnic
size) the depth of the table means you need to have the K-Line
right on
the
rear edge and the 6M pre-amp protrudes far enough back that if
you are
up
against a barrier of some sort, the cables push the K-Line
forward and
reduce the work space area such that little room is left to
operate in a
comfortable manner.
I could pontificate forever on the drawbacks when operating
portable
but I
am probably not a member of the right choir.
Maybe an OEM will come up with a 'plug-in' internal 10M pre-amp
designed
for a K3.....now that would solve everything for me and I
wouldn't have
to
plead my case....:-)
It's all about choice folks!

Agreed Gary,
I too would be interested in an internal 10M pre-amp (or an
internal
combo
6-10M pre-amp).
I already have the PR6 but like you say it (in stock form)
protrudes
so
far
out behind the rig that it almost impossible to use for
portable work.
Mounting it internally is the way to go and I reckon a combo
pre-amp
would
sit nicely where the internal 2M transverter normally goes.

Well I do hope there will be a version for 10M perhaps that
will
install
within the K3. Much as it would be nice to have I am not
going to buy
more
boxes needing to be plugged in, cabled or whatever.
Whilst I understand some folks have space available and can
wire in
as
many
boxes as are available, those of us who operate portable tire
very
quickly
of sorting cables, boxes and the resultant tangled leads.
I guess I will have to wait and see what is produced but another
external
box such as the 6M pre-amp which protrudes too far and can
easily be
knocked around is a non starter for me no matter that I could
use it,
it
is
what it is, a box too far.
