Jim...Unfortunately I can only offer you what I was told via email about the
Kachina. Someone was using it at a special event station and complained that
the QSK was very poor; mind you, I don't know personally.
As for the Omni 6+ that resets to 14000kc when it's turned on, I'm
sure
your going to find when that fellow reads the manual and learns how to set the
menu selection, that the Omni 6 will turn on at the QRG that it was turned off
at. Mine does.
I sure disagree with the person stating that "ultimately IF/DSP filter
performance will surpass cascaded crystal filters." The reason I disagree
with
that statement is because digital switching will probably NEVER have the stop
band characteristics that a crystal filter can have, if designed correct. They
will probably make good strides in using IF/DSP for SSB, but I would almost
(NOTE: 'almost') bet my Omni 6+ that it wont happen for CW operation.
As for TenTec's final testing, I have not witnessed it. However not
too
long ago TenTec got a military contract to build receivers to MilSpec and I
think the result of that contract is a lot of what we see in the Omni 6.
Meaning the very good pc board layouts, the excellent cabeling routing, and
the
overall significant improvement in the design of the Omni. I think most of
their testing is now computer controlled, and certainly with computer
controlled testing some things can be missed. All depends on the
communications
between the engineers and the computer programmer!
