I purchased a Z100A with the idea of interfacing it to a specific brand/model
of radio. I investigated the Z100A requirements to initiate the control of the
tuner via the transceiver. From my earlier work, I don't see there is a
command from the K3 that will support the requirements of the Z100A. However,
there are many ICOM radios that do have the provision. Thus the command comes
from the radio.
From the LDG manual:
"The LDG Z-100A includes the IC-104 DC power cable, as well as a three
foot IC-100 Icom interface cable. However, interface cables for a
plethora of other radios are available as an optional purchase,
definitively making the Z-100A the last tuner you'll ever need to purchase.
Press "Tune" on Tuner - Keys Automatically
* IC-105 Alinco interface cable - uses EDX-2 jack, DX-70 and DX-77
* IC-108 Yaesu interface cable - uses TUN/LIN and KEY jacks, FT-891,
991/A, 857, 897, 100
* IC-109 Yaesu interface cable - uses TUN/LIN jack, FT-DX10, 1200,
FT-950, 450 (NOTE: Do not select external tuner in settings)
* IC-115 Yaesu interface cable - uses LINEAR jack, FT-DX101D, 3000
* IC-106 Kenwood interface cable - uses AT-300 jack
* IC-105 Alinco interface cable - SR8T, SR9T"
* Compatible with any Icom radio that is AH-4 or AH-3 compatible. (6M
tuning from Tuner button for radios that are only AH-3 compatible)
* Partial radio list: IC-706, 703, 718, 7000, 7100, 7200, 7300, 7410,
746, 756, 7600, 7610 (and all variants).
I find nothing to indicate the LDG100Z will interface with the K3. In
reviewing the signals on the ACC connector on the K3, I do not find one
dedicated to the TUNE function. See page 20 in the manual, ACC(Accessory I/O)

I have tried to find a cable that goes from my K3 to the LDG Z100A tuner but
all I see is just a cable with a Molex like connector going to the tuner and
nothing on the other end of the K3 except bare wires (i.e. no connector). Does
the tuner have to get connected to the K3 ACC jack?? Or does someone have a
wiring diagram so I can marry the correct connections between the 2 units?
