The AT-AUTO employs an embedded microprocessor to precisely adjust the tuning network comprised of a split-stator capacitor and a roller inductor, arranged in a classic "T-Match" configuration. The pictures and descriptions shown here are of the existing version(s) of the AT-AUTO tuner prior to its production cessation.Ī new web page for the AT-AUTO II is coming in the near future. It is undergoing a redesign for release soon. Note: The AT-AUTO is currently not in production and not available for sale. Please see the CX-AUTO link for additional information. 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. Here's a great tuner for packing into the woods or for SOTA work! Use it mobile, portable or in the shack.Join our AT-Auto discussion on Yahoo Groups today! * SO-239 in and out connections for dipoles, verticals, beams, G5RV, OCF, Cobra, etc. * 1.8 to 54 MHz coverage (continuous coverage for MARS) * Latching relays for ultra-low power consumption * RF Power: 0.1 to 125 watts SSB and CW, 30W on PSK With all of these enhancements, you'd expect to pay more, but LDG offers the Z-100Plus tuners at an affordable price. Z-100Plus antenna tuners now include an internal frequency counter, so the operating frequency is stored with tuning parameters to make memory tunes a really fast 100 milliseconds (full tunes take an average of only 6 seconds). Current draw while tuning is less than 100ma. These small and simple-to-use tuners will run on any voltage source from 7 to 18 V, or six AA batteries will run them for a year of normal use. LDG Electronics Z-100Plus Automatic Antenna Tuners sport 2,000 memories that store both frequency and tuning parameters! LDG Electronics Z-100Plus Automatic Antenna Tuners
