Kessler AT-AUTO Operating Manual page 124

All circuitry used by the AT-AUTO
Peak-Hold metering circuitry. The Peak-Hold circuitry and the SWR meter are included
as an operator convenience only during manual tuning operation and are not used by the
AT-AUTO during the process of automatic tuning.

How does the AT-AUTO
available to the amateur radio community?
Answer: This is the ONLY fully-automatic antenna tuner purposefully designed and built
to conservatively handle a continuous 1500 W CW carrier. Most other automatic tuners are
a mere collection of fixed Inductors and Capacitors that are switched in/out by relay and as
such are generally limited to 600W PEP or less.

used in our highly-acclaimed manual tuners, but they now are adjusted by stepper motors
under microprocessor control.
Is this a Ham-Band only tuner? Will this work on the MARS
frequencies?
Answer: The AT-AUTO
There are match memories dedicated to the entire match range of the tuner. Non-volatile
memories for MARS frequencies as well as other Federal/Civil frequencies are incorporated
into the AT-AUTO

Why does the AT-AUTO
Answer: The actual tune time of the AT-AUTO
very typical. The 30 seconds quoted is due to the transit time it takes for the AT-AUTO
to reposition the roller Inductor from one extreme to another such as QSYing from 160m to
10m.
The actual tuning starts once the Inductor and Capacitor have been pre-positioned for
the frequency/band of operation. When operating in Smart QSY mode, the AT-AUTO
automatically recalls its matched settings from non-volatile memory and subsequent tuning
is likely not necessary.
