Additionally, the AT-AUTO may also be shared with up to 8 different radios when utilizing a CX-AUTO on the 'input-side' of the AT-AUTO. The AT-AUTO is also capable of automatically selecting up to 8 coaxial outputs (via the companion CX-AUTO coaxial switch). While the serial port is not necessary for automatic tuning, this 'Smart Mode' of operation greatly speeds the entire process of changing frequencies. By doing so, the AT-AUTO instantly follows frequency changes (VFO adjustment, etc.) and immediately recalls and sets the L & C for the new frequency - without the need to generate an RF carrier! The recalled match should provide an excellent SWR so that when RF is finally applied, subsequent tuning will not be necessary. The AT-AUTO is also able to obtain frequency information via the radio's serial data port (for these compatible radios so equipped). The default behavior is highly customizable to suit individual needs. Once a good match is found, the new match settings are stored in memory for subsequent recall. If the SWR is still excessive, the AT-AUTO automatically begins tuning, and provides user prompts during the entire process via the LCD. Whenever the SWR exceeds the 'Tune-Start' SWR, the AT-AUTO then counts the RF carrier frequency, looks up previously stored Inductor (L) and Capacitor (C) settings for the frequency of operation and then repositions L & C to the recalled settings. As long as the SWR is below a user-selectable threshold, the AT-AUTO provides a 'Good Match' cue in the Liquid Crystal Display (LCD) and takes no further action. The AT-AUTO continuously measures forward and reflected RF power. The AT-AUTO is quiet and reliable, and with its industrial-rated stepper motors, provides a superior impedance match to that provided by the loud clanking boxes of relays provided by the competitors. It provides continuous coverage tuning from 1.8 - 54 MHz (including MARS, DoD, and commercial frequency bands, etc.) and is rated for 1500 W continuous carrier operation. The AT-AUTO is a fully autonomous, fully automatic impedance matching network (an antenna tuner) that employs an embedded microprocessor to position a conventional roller inductor and a split-stator variable capacitor.
