897 Autotune

AT-897 Autotune

If you own a Yaesu FT-897 and want a broad range
automatic antenna tuner, look no further! The AT-897
Autotuner mounts on the side of your FT-897 just like the
original equipment. We even added the ability to mount
the "feet" on the side of the tuner so when you are
transporting your rig by the handle, you can safely set it
down and not worry about scratching the case.

The AT-897 is microprocessor controlled and features the
tuning ability our customers have come to expect from our

roducts. The tuner has a front panel button to initiate the
tuning sequence and will bypass the tuner if pressed
momentarily. The red LED lights during while the tuner is
active.

The AT-897 can be used as is or in conjunction with the
W4RT One-Touch Tune interface. (Please read our FAQ
for configuring your radio with the W4RT One-Touch
Tune) Without the W4RT interface, you will change your
mode to one which provides a constant carrier (AM, FM,
CW, or Packet), key your transmitter, press the tune
button, wait for the tuner to tune, then un-key. The W4RT
interface allows you to just press the tune button on the
AT-897 to accomplish tuning the antenna, no matter what
mode you are in. The interface takes care of it all.

The AT-897 takes power directly from the CAT port of the
FT-897 and provides a second CAT port on the back of the
tuner so if you are using another CAT device, hooking it
up couldn't be easier.

If you are a QRP enthusiast or plan on operating
via internal batteries, the AT-897 is your tuner!
The AT-897 does not need a fan, let alone one
that is constantly running. Current consumption
when it is tuned is in the micro-amp range. Since
we use latching relays, you can even remove

ower from the tuner after you have tuned on the

band you are going to operate!

The FT-897 is a great radio. The FT-897 / AT­897 combination makes a fantastic shack!
