[Elecraft] K1-4 Ant Tuner Question

[Sandy]

The latest permutation of the K1 is rigged for easy installation and
removal of the KAT1 tuner!  So you can build the K1, operate it,
and build and plug in the tuner when you are ready for it.
The power sensing network for the K1 alone is a resistive voltage
divider, there is a jumper strip (a la computer configuration
configuration jumpers) to go to the SWR bridge in the KAT1
to indicate power and VSWR when its installed.  There is
also a bare wire jumper used in one of the KAT1 sockets
that must be pulled when the KAT1 is plugged in.  The most
"piddley" part of the installation is keeping the spacers in place on
the long screws that mount the KAT1.  I solved this with
a couple of rubber band sections between screws and spacer
inside bore to retain the spacers on the screws when the KAT1
is removed, if needed to realign the 4 band board.  (None of the
adjustments are accessible on the 4 band card when the KAT1 is
piggy-backed on top of it.)

I enjoy my K1 very much!  The KAT1 is VERY handy in the field
and means one more piece of gear you don't have to tote around and
connect up, etc.  I am presently waiting for a 2 band board from
Elecraft to convert to 160 and 80 meter operation.  (The 160 meter band
is not an offered option, but is easily added to one position of an
extra two band card.  Elecraft has all the needed parts, toroid cores
EXCEPT for the 9.8 Mhz crystal, which presently must be ordered
from ICM or any reputable crystal manufacturer.)

| Hi everyone.
|
| I have been on and off the list for a while, and I have just gotten back on,
because I think I might finally be ready to get started on a K1.  I have one question
for now (although, I am sure that number will increase within a month or so.  Due to
limited $$$ up front, I am thinking of buying the K1-4 first, then acquiring the
antenna tuner at a later date when I fall into a few more pieces of eight.  Is adding
the AT well after the main radio is completed any more difficult or time consuming
(read partial disassembly), or is it no different than having it all at the same
time?
|
| I assume it doesn't matter, but it would KILL me to have the K1 sitting here for
months and not be able to assemble it.
|
| Thanks for your attention.

| Regards,
