Note: Whenever a successful match is found the precise L and C settings are
stored into memory, and the AT-AUTO

If the CW carrier is interrupted before tuning is complete, the AT-AUTO
diately cease tuning and provide an error message indicating that the carrier was lost and
that tuning was aborted. The user may also terminate the tuning process by momentarily
pressing the "Mode" button.
In order for the tuning process to be successful, as L and C positions are adjusted,
the corresponding variations in SWR must be discernible by the AT-AUTO
circuitry. If the AT-AUTO
while L and C are set for 160m operation, there may be NO discernible variation in SWR
as L and C are manipulated, and automatic tuning will very likely fail. Therefore before
commencing automatic tuning, the AT-AUTO

Smart QSY
The AT-AUTO is designed to operate in a Smart QSY mode by automatically following
(tm)
frequency changes of those transceivers so equipped with a CI-V or CAT serial I/O inter-
face. When operating in Smart QSY mode, the AT-AUTO
transceiver operating frequency via the serial I/O interface and then recalls L and C match
settings from memory and rapidly presets L and C as appropriate. As the transceiver changes
from frequency to frequency, or from band to band, the AT-AUTO
along and presets L and C without the need for the an RF carrier or other operator inter-
vention. This is presently implemented for Icom radios with CI-V interface and for Elecraft
(K-2, K-3), Flex Radio (SDR-1000, FLEX-5000), TenTec (Omni VII, Jupiter), and many
Kenwood and Yaesu radios with CAT interfaces.
