Re: [Elecraft] KX3 ATU Modes

[Don Wilhelm]

Ron,

It will not automatically tune without user action.  Tap the ATU TUNE to 
initiate a tune.
Once you have "trained" the antenna on each band segment, it will 
automatically recall those last used tuning solutions when you return to 
that band segment.  The latter is the "automatic" action.


See the KX3 manual page 14, lower half of the right column.

If so, how do you set the SWR at which it begins the tuning process.

I only have it in BYP when using the vertical antenna with the LDG 
RT100 remote tuner.

Sorry, I misunderstood what AUTO meant.
A better label would be ATU ON or ATU INLINE.
AUTO implies that it will automatically do the tuning.

Semantics :-)

No. AUTO in the KX3 (or K3/K3S) means that the automatic antenna tuner is 
in-line rather than bypassed.

To tune, tap ATU TUNE. The SWR is displayed, and it should decrease as the 
algorithm progresses.

If the final SWR is higher than 2:1, you can tap ATU TUNE again within 5 
seconds to initiate a broader search. This is useful with very narrow-banded 
antennas, or those that are electrically short or close to a multiple of a 
half-wave (very high-Z).

The ATU stores up to 32 LC network settings per band. These settings are not 
recalled as you move the VFO in RX mode, as that could be distracting. But they 
are recalled when you transmit, or when you do ATU TUNE, change antennas, do 
A/B VFO swap, etc.

You can clear all of the ATU LC memories on a given band by going in to the ATU 
menu entry and holding CLR (hold of the RIT/XIT offset control).

In CW mode, the rig tries to avoid interfering with your sending when the ATU 
requires retuning for a new transmit frequency. The first time you transmit in 
a segment that requires an LC network change, the firmware will wait for the 
first significant pause (letter space), then update the ATU. This is indicated 
by the ATU icon flashing a couple of times. It's possible that your first 
transmission will be at a somewhat higher SWR because of this behavior, but it 
has the advantage of not chopping off the first element due to ATU relay delays.

[Walter Underwood]

It does automatically switch to a remembered tuning as so you as you change 
bands or tune to a new frequency. That seems at least “semi-auto”.

Re: [Elecraft] KX3 ATU Modes

[KENT TRIMBLE]

Not when the menu item does specified things.

Manufactures spend enormous time and money to write manuals so operators 
know what those specific things are.


Semantics implies words, and words imply reading.  Neither imply ESP.

The printed word is not dead.
