Auto-tuners have been around for years, but most of them use clacking relays and lumped components so that the match is always just a little bit off. Now Palstar has reinvented the auto-tuner with continuously variable components for a perfect match every time, and capped it off with a power rating of 1500 watts, making it the highest power-rated auto-tuner in the industry. New Feature! QRO Keyline The latest version AT-AUTO (2.08) features the QRO Keyline. This locks an outboard amplifier into standby until the auto tuning is complete. This feature protects your expensive QRO amplifier from damage caused by the high voltages that can occur when QRO power is fed into a mis-matched load. (This feature requires a hardware modification; call factory for pricing to retrofit older units.) Auto-Tuning with Palstar Quality The AT-AUTO features a 2 line, large character display for reading the status of antenna feed, frequency, and up to 250 channels of memory each for coax and balanced feeds. The AT-AUTO has a custom built differential capacitor and a custom built ceramic body roller inductor that are tuned by two high-speed, microprocessor-controlled stepper motors. Active Peak/Peak Hold Watt Meter Integrated into the AT-AUTO is Palstar's Active Peak/Peak Hold wattmeter allowing you to measure and display forward power, reflected power, and SWR simultaneously on its dual movement meter system. The meter has 300 and 3000 watt range settings. Rig Interface Connectors The AT-AUTO has data connectors that interface to most recent Icom, Kenwood and Yaesu transceivers, so that the tuner will automatically follow band and frequency changes. Have an older rig that does not have an interface? No problem, the AT-AUTO incorporates a frequency counter. Just provide the AT-AUTO with a frequency sample by keying the transmitter for less than a second, and it will tune for that frequency. Field Updatable Firmware As new software features are added to the AT-AUTO, they can be downloaded and installed right in your shack, no need to return it to the factory for update. TWO Year Palstar Factory Warranty Palstar stands behind the AT-AUTO WITH a two (2) year limited warranty. Like most Hams you've probably tried tuners made by the "other" guys.

When you buy a Palstar tuner you're not just buying a piece of quality equipment - you're buying a product from a Made in the USA manufacturer carrying on the American Ham tradition.
