LDG AT-897 PLUS BOLT-ON MEMORY AUTOTUNER FOR YAESU FT-897, FT-857 TRANSCEIVERS. The LDG AT-897Plus provides semi-automatic antenna tuning across the entire HF spectrum plus 6 meters, at power levels up to 125 watts. It will tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. It will match an amazing range of antennas and impedances, far greater than some other tuners you may have considered, including the built-in tuners on many radios.

The AT-897Plus is similar to previous LDG tuners, but is specially engineered to integrate with your Yaesu FT-897 HF radio. The LDG AT-897Plus connects to the CAT (Computer Automated Transceiver) port on the back of the radio. The CAT interface allows an external device such as a PC or the LDG AT-897Plus to control the Yaesu FT-897 by sending it serial commands. The AT-897Plus takes advantage of this interface to simplify the tuning process -- one button push is all that is needed in order to switch the radio to AM mode, reduce output power, transmit a carrier, measure the transmit frequency, and then restore the radio to its previous mode and power level!

The LDG AT-897Plus is powered by the transceiver’s CAT interface itself, so there is no additional power cable required to use the LDG AT-897Plus. Latching relays are used, so the LDG AT-897Plus consumes no power when not tuning.

The LDG AT-897Plus improves upon the previous LDG AT-897 automatic antenna tuner, in that the memory has been expanded to 2,000 frequency memories. The transmit frequency is actually read directly from the Yaesu FT-897, so memory tuning is a snap.

  • 0.1 to 125 watts SSB and CW peak power, 30 watts on PSK and digital modes and 6 meters1
  • Latching relays for ultra low power operation.
  • 2,000 memories for instantaneous frequency and band changing.
  • Powered from the radio -- no extra power supply to hook up.
  • Designed specifically for the Yaesu FT-897/FT-897D HF transceivers. Can be mounted directly to the side of the FT-897.
  • Pass-thru CAT port allows AT-897Plus to control the FT-897 over the CAT bus while still allowing a host PC to also control the radio. 
  • Pass-thru CAT port waits for idle CAT activity before controlling the transceiver.
  • 1.8 to 54.0 MHz coverage. Frequency for memory storage is read from the radio via CAT.
  • Tunes 6 to 800 ohm loads (16 to 150 on 6M), 24 to 3200 ohms with optional 4:1 Balun.
  • For Dipoles, Verticals, Vees, Beams or any Coax Fed Antenna.
  • CAT Din 8 cable included.
  • Optional external Balun allows tuning of random length, long wire or ladder line fed antennas. See web site for details.
  • Less than 1 mA power consumption in standby mode -- ideal for battery operation.
  • Dimensions: 11.25”L x 3.25”W x 1.5”H. 
  • Weight: 1 pound 6 ounces.
