AT600Pro Tuner

LDG AT-600pRO TUNER

AT600ProFS

The AT-600Pro will handle up to 600 watts SSB and CW and 300 on RTTY (1.8 – 30 MHz) and 250 watts on 54 MHz. It features LDG’s state-of-the-art, processor-controlled Switched-L tuner. It will match virtually any kind of coax-fed antenna, including Yagis, dipoles, inverted Vs, slopers, loops, just about anything. It will typically match a 10:1 SWR down to 1.5:1 in just a few seconds. You can also use the AT-600Pro with longwires, random wires and antennas fed with ladder line just by adding a balun.

The AT-600Pro features two antenna ports with a front-panel indicator showing which is in use, and separate memory banks for each antenna. Easy to read LED bar-graph meters showing RF power, SWR and tuner status, tactile feedback control buttons and an LED bypass indicator complete the user interface. Any power source from 11 – 16 volts DC can be used; the AT-600Pro draws only 750mA during a tune cycle, much less when not tuning.

600 Watts SSB and CW, 300W RTTY (250 watts on 6M)

AT1000pro Tuner

AT1000ProF-thumb_

Building on the success of the AT-1000, LDG Electronics has refined and expanded its flagship 1KW tuner.

First and foremost, the AT-1000Pro has an Auto mode that automatically starts a tuning cycle any time the SWR exceeds a limit you set. Also, there are provisions for two antennas; you can switch between them any time you need. For each antenna, there are 2,000 memories that store tuning parameters for almost instantaneous tuner setting whenever you transmit on or near a frequency you've used before. Just key and it tunes! The AT-1000Pro will operate at any power level between 5 and 1,000 watts peak RF input.

The AT-1000Pro has a much larger, easier to read cross-needle meter with two selectable scale ranges (100 and 1,000 watts). Each control button has a built-in LED indicator so you can see the tuner's status at a glance. The AT-1000Pro will interface with many popular transceivers, enabling their TUNE button to control the AT-1000Pro's operation. Dedicated control buttons allow you to fine-tune capacitance and inductance on those rare occasions when the AT-1000Pro can't find a perfect match by itself.

The AT-1000Pro will tune from 1.8 to 54.0 MHz continuously, and will match an amazing range of antennas, from Yagis and dipoles to inverted-Vs and slopers; virtually any coax-fed antenna from 6 to 1000 ohms impedance (16 - 150 ohms on 6 meters). Tuning time is usually under 6 seconds. If you're transmitting near a frequency with stored tuning parameters, it will set those parameters in under 0.2 seconds. Longwires or antennas fed with ladder line require an external balun.

All LDG products include the new 2-year warranty on parts and labor. The AT-1000Pro also include the necessary cables for DC power and radio interface; you're ready to operate right out of the box.

YT-100

YT100FS

Yaesu radio are among the best, and LDG makes a dedicated bolt-on tuner for the FT-897, but that leaves a big chunk of the Yaesu product line with no dedicated tuner. Of course, most LDG tuners will work just fine with Yaesu radios, but it sure would be nice to have it integrated to the radio.

LDG's new YT-100 is just that. An included CAT cable interfaces with your FT857, FT897 and FT-100 (including all D models). This makes it an integrated tuner powered by the interface. No extra power cables are needed. Just press the tune button on the tuner and everything else happens automatically! The mode is set to carrier and the RF power is reduced, a tune cycle runs and the radio is returned to the original settings.

Specifications:

RF Power: 1 to 100 watts SSB, CW and digital modes.
Latching relays for ultra low power consumption
Built-in CAT interface for FT-100(D), 857(D) and 897(D) radios. Powered from Yaesu radio over CAT port.
CAT thru port for computer control of radio. 4800 baud.
2000 memories sorted by frequency.
1.8 to 54 MHz coverage (continuous coverage for MARS)
Tunes 4 to 800 ohms. (16 to 150 on 6M)
SO-239 in and out connections for dipoles, verticals, beams, G5RV, OCF, Cobra, ect.
Dimensions: 7.0"L, 7.0"W, 1.5"H. Weight: 20 ounces
Includes 1 foot CAT interface cable and 1 foot coax jumper.
