Please run your data through??

I have a 3.8 dBi 2 meter antenna and at 10w they called for 2.34' in a controlled environment.

I actually use this data-cable on the FT-857D for remote tuning.? The tuner is mounted behind the battery.? In the lower-left photo, the upper-right corner, the red push-button is the tuner start button.? I operate mobile differently than most.? I¡¯m a retired disabled combat veteran, Army DOC says I need to keep walking.? On the local 2m and 70cm SSB nets I can do about 3 MPH.? On any HF operation I need to go slower because the big antenna sways more.

The FT-847 does not have an ACC jack, and the necessary TX-REQ signal is not on any other connector pin;?
so there is no way to interface the FT-847 to the LDG AT-200ProII.
?
Unlike the FT847, the FT-857D has a 3.5mm ACC jack, where the ring (TX-REQ) connects to the LDG _KEY signal (3.5mm TRS TIP),?and the sleeve is common, using the LDG Y-ACC cable.??
?
FYI: On LDG auto-tuners with 3.5mm jack, tip is _KEY,? ring is _START,? and sleeve is GND.?
A description of the _START and _KEY signal operation on the Icom and LDG antenna tuners is on page 6 of
