[TVARC] AD4K - IC-7300 & LDG AT-1000ProII Tuner

[Steven Roth]

I need some help.  I have been using an IC-7300 (Radio A) hooked to an LDG
AT-1000ProII tuner (Tuner A) at my Virginia location for two years.  Rather
than hauling eqpt back and forth (I am a snowbird) I duplicated equipment
here in Florida.

I have been using an IC-7300 (Radio B) and LDG AT-600ProII tuner here in FL
and recently upgraded to the AT-1000ProII (Tuner B) that I got at HRO.
When I received the AT-1000 it would not work properly so I contacted HRO
and they sent me another one.  That, too, did not work correctly.  I
contacted LDG and have been working with one of the techs there to
determine what is not happening.  The holidays hit so he said they would
work on the issue after the holidays.  HRO tested the one I sent back and
said that it is working properly (undefined)

In the meantime, I have been trying to determine just what the problem is
because my LDG-600ProII works fine with my radio (Radio B) but the
AT-1000ProII (Tuner B) does not.

My analysis - with the units hooked together using the special interconnect
cord, when you push the "TUNER" button on the IC-7300 it provides low-level
RF to the tuner and tells the tuner to tune.  On the screen of the IC-7300,
top left, there is a box that shows "TUNE" just above the red TX icon.  The
TUNE color changes from white to red when pushing the TUNER button to force
a tune on the tuner.  That functions with the AT-600 tuner that I have but
does not function when hooked to the AT-1000 unit - there is no white TUNE
box, so when I push the TUNER button it blinks red TUNE but nothing happens
and the AT-1000 sends an error message saying there is no RF being
provided.

Are there any local members of the TVARC using the same combo - IC-7300
with AT-1000ProII or any LDG tuner?  If so, perhaps he/she could contact me
to compare notes.

Thanks, Steve Roth  AD4K
