I have a TS-590 with the internal automatic antenna tuner, and then, I also
have the LDG AT1000PRO II external automatic antenna tuner. I do not have to
disable my TS-590's internal tuner. However, I have read that you should
never use the internal tuner when using an external tuner because it can
severely damage your equipment. So, I do not. There is no reason to use the
internal tuner when I have the external one that works extremely well.
I do not have any trouble what so ever using the LDG AT1000PRO II tuner; I
just listen to its sounds when I press its buttons and the sound coming
from my TS-590. I have my TS-590 set-up so I can put it in the tune position
with one of the programmable function keys, and when it is in the tune mode,
it automatically reduces my power down to 10 watts to protect my rig during
tune-up and to minimize QRM on the band on which I am tuning up. I simply
press the auto-tune button on the LDG tuner, and it usually tunes almost
instantly, unless I am on a new band or way away from any frequency I have
worked before. I have another button on my TS-590 that allows me to monitor
my SWR. Occasionally, even when the LDG gets done tuning in the automatic
mode, I'll see if I can improve the swr a little more with the manual
controls/buttons on the tuner, one set of up/down buttons for impedance
adjustments and the other up/down buttons for capacitence fine tuning. Often
I cannot improve what the tuner did in automatic mode; in fact, many times I
only made it worse! Frankly, I really like the way my set-up works.

David and all:
When I e-mailed LDG a month or two ago , asking the question about the
ability of LDG auto-tuners like the AT1000 to interface directly with
Kenwood rigs such as the TS590, I was given a pretty convincing "no
answer". I think confirmation of this also appears on the LDG web site.
To me, this means that the TS590's internal antenna tuner would have to be
manually disabled when using one of the LDG models.
If I am incorrect, I hope someone on list will let me know.

Subject: ldg kt-100 tuner
Hello all:
There is a youtube video put out by ldg on the kt-100tuner(did a "google"
search), and perhaps it will answer some questions. It appears that the
590's internal tuner has to be bypassed momentarily when tuning the 6 meter
band since that band isn't supported by the origianal at-300 tuner. I
believe that all other ts-590 tuning can be accomplished "seamlessly" using
the transceiver's front panel tune (with corresponding feedback beeps for
tune, or no tune)button. The video makes several references to the kt-100
owner's manual as well, and maybe answers your questions more fully.
Failing the foregoing, you could always contact ldg directly via
e-mail(contact info on their site) for definitive answers. Hope that is
somewhat helpful.
Best regards,
David S. Pearson-wa4dsp
