The Z-817 is the ultimate autotuner for QRP radios including the Yaesu FT-817 and FT-818. The Z-817 interfaces to the CAT port (ACC) on the back of the FT-817 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). A CAT connection cable is also included but NO coax jumper! Latching relays are used so that power consumption is Zero when not tuning allowing a set of batteries to last about one year.
