Yes, that is correct. Just feed it some RF and if the SWR is above
1.5:1, if memory serves, it starts to find a solution that yields a low
SWR.

I used to run the SGC-230 tuner at the base of my antenna.
As I recall it has a auto mode that does not require a tuning circuit

I am looking at remote antenna tuners. I have seen several controllers
for
the ICOM AH-4 tuner. My questions are about operation with a K3s.
1. Is there a limit to the time that 10w of RF can be sent to the
AH-4
via the K3s Tune button?
2. All circuits specify a momentary switch, but does momentary mean
0.1sec, 1.0sec or 5seconds? Does the time matter?
3. When the complete signal returns from the AH-4 should the Tune RF
or
the momentary be terminated immediately?
4. Is there a combination of momentary or Tune RF that will damage
the
AH-4?
I have an AH-4 which worked with a home built controller for some
months,
and then became operationally intermittent and final fails to work at
all.
That makes me gun-shy, about buying another even though the AH-4 gets
excellent reviews on eHam, almost all of which are based on an ICOM rig
control.
