K3 ATU tutorial help

[Charles Johnson-2-3]

I have just installed the ATU in my K3 and can't seem to find an
explanation or tutorial on how it should be operated. I am used to the
ICOM tuners and they automatically retuned and recalled settings as you
changed frequencies and bands. The K3 ATU seems to recall previous
settings, but only if I first manually force it to tune on a particular
frequency. I must be missing something, but the manual or the K3 web
site has almost no information on how the tuner is supposed to function.
I have also searched the archives of this reflector, but the subject
doesn't seem to be addressed anywhere. Maybe my new tuner is broke? Just
how automatic is this tuner? Is there some process I have to go through
to help the tuner 'learn'. I have it set up in the CONFIG menu, but it
just doesn't work quite like I expected it to.
Thanks, Charlie

You have to manually tune it throughout the band for it to learn the
settings to be recalled.  You can either do this by tuning about every
20kc or you can download K3_EZ and then you can click a button and it
will automatically do the tuning for you.  It just tunes qsy's tunes
qsy's again until its done the whole band for you...

You can download K3_EZ here: http://home.roadrunner.com/~n2bc/SW.htm

If you want to read more about the tuner's features you can find that in
the software release notes: http://www.elecraft.com/K3/hfwnotes.rtf

In that document you'll see the features of the tuner that were added in
version 3.03.  I highly recommend that you read through that document in
its entirety as there are quite the number of features that are only
documented there for the most part.  Or perhaps also download the manual
errata as many of the features have probably been added to that
document.

I've pasted the new KAT3 features below>
New ATU (KAT3) Features



* MULTIPLE KAT3 ATU DATA SEGMENTS PER BAND/PER-ANT.: 10 kHz

per segment on 160 m; 20 kHz on 80-12 m; 50 kHz on 10 m; 200 kHz

on 6 m. This keeps narrowband antennas in tune across the full ham

band.Note 1:You do nothave to go through each band and do ATU TUNE

on every segment. The K3 will use the saved LC data segment closest

to your present VFO location. Note 2: You can erase all of the stored LC

data for a given band by tapping CLR in the CONFIG:KAT3 menu entry.


* AUTOMATIC KAT3 LC NETWORK UPDATE ON TRANSMIT: Each time

you transmit, the K3 first determines whether you’ve moved the VFO

closer to another stored ATU data segment. If so, it will re-load the
KAT3 with

this data, and flash the “ATU” icon twice, briefly. You’ll hear one or
more

relays on the KAT3 change state. This will not interrupt transmit.


* ATU MODE STORED PER-BAND, PER-ANTENNA: You can now set

up the KAT3’s mode (AUTO, BYPASS, etc.) on a per-band/per-antenna (1/2)

basis. This is very useful if you have well-matched antennas on some
bands,

or a dummy load connected to one of the ANT jacks.
