All:
Is it normal for the T1 ATU not to stay in tune mode after tuning an
antenna? I've noticed that my T1 will occasionally default back to power
mode so I need to switch the T1 back into tune mode whenever I switch
bands and need to re-tune.

Thanks Bill, but I wasn't clear the options I was looking for were how to use
he T1 with the EndFed antenna I have with the WSPRlite, given that the T1
requires 0.5W and the WSPRlite outputs only 0.2W. Odd as it sounds, I'm

on options other than tuning up with another radio
I recently bought and built the T1 ATU, and it works great - no issues from
first power up on. I should say it functions correctly - but I have a problem
with the battery voltage displayed by the ATU. It seems to be over 1V high. I
don’t expect calibrated precision, but a semi used 9V
I'm taking a parts inventory and noticed that I've been provided with a 78L06
instead of an 78L05. Is this expected or should I contact Elecraft for the
specified part?
Thanks,Scott N1ST

I have a T1 ATU and would like to use it remotely.
Is there a way to do it without the added wires for the TUNE control?
Mt SGC ATU has the ability to automatically tune when the SWR is above a
certain limit.
Is there a way to make the T1 operate the same way?

Sidney- This is normal.
Take a look at the schematic for the T1 tuner (in the manual) and you will
see there is a DC path through transformer T2.
BTW- you can not/should not put your swr meter between the T1 tuner and the
antenna. It rightly belongs between the tuner and the radio.

BTW Sidney-
If you are using the K1 you bought from me, keep in mind it has the KAT1
internal tuner. There should generally be no need to use the T1 with it. If
you -do- use the T1, remember to put the internal tuner in the K1 in CLS or
CLP mode. See page 11 of the KAT1 manual I provided.

Something strange (?) is happening with my T1 and a Yaesu FT817 using the

If I return to the previous band, the yellow light is flashing instead of the
green one, as it is supposed to do. Sometime, the green light flashes

A dipole cut for 40 meters will provide a high feedpoint impedance on 20 -
and the L network used in the Elecraft tuners do not do high impedances very
well.
Of course, all that does depend on your feedline length as well as the
flattop length - the feedline will act as an impedance
Craig,
Thanks for the info. I checked out the Elecraft baluns you
mention and will order one up. This sounds like a reasonable
size setup for the times when I can get up a center pole to
support the antenna. Is there a preferred height for the apex
or do I just go as high as I can?

Kieth,
This is a portable field antenna for me, and I have made the feedline from a

QRP-L did some tests on various feedlines, and this turned out to have good
loss characteristics, and it is flexible and lightweight which
I find the T1 does very well with a very high impedance. I end feed
1/2 wave wire connected right to the T1 with a counterpoise and it
matches right up! I ran a test and the T1 can match a 4700 ohm resistor.
So it's not bad with high resistance.

Rick,
Like everything else It all depends...
In your particular case, it depends on how the elements are oriented - and
that includes the counterpoise. It also depends on the proximity of ground
and other objects. Is the counterpoise in the air, or is it laying on the
ground?
That is the

Hi All,
I am considering using my T1 to tune a couple of attic antennas, a 40 mtr
dipole with drooping ends, and a horizontal loop of about 130 feet total

in the coax from shack to attic. I would plan to use a
Being an engineer I am sure you enjoy putting these kinds of pieces
together.
OTOH, the Ameritron 4-position switch placed in your attic will switch up
to four antennas. The control voltage to activate the switch rides on the
