|Amateur Antenna Tuners
The LDG Z-817 is the ultimate autotuner for QRP radios including the Yaesu FT-817/817ND/818ND. The Z-817 interfaces to the CAT port (ACC) on the back of the FT-817/818 radio with the provided cable. Tuning could not be simpler; one button push on the tuner is all that is needed and the Z-817 takes care of the rest. It will switch to PKT mode, transmit a carrier, tune the tuner, then restore the radio to the previous mode! 2000 memories cover 160 through 6 meters.
Of course, the Z-817 will also function as a general purpose antenna tuner with other QRP radios. Just transmit a carrier and press the tune button on the tuner. The Z-817 is powered by four AA internal alkaline batteries (not included), so there are no additional cables required to use the Z-817. Latching relays are used so that power consumption is zero when not tuning allowing a set of batteries to last about one year. Includes 3 foot CAT DIN-8 radio interface cable. Also requires a coax jumper cable which is not supplied.
The LDG Z-817H was similar, but could handle up to 75 watts. LDG discontinued this "H" version. Click here view Z-817H
