LDG Z-817 Automatic Antenna Tuner - Only AU$199

The Z-817 is the ultimate autotuner for QRP radios including the Yaesu FT-817(D). 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), 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.

Specifications:

  • RF Power 0.1 to 20 watts SSB and CW, 5 watts for digital modes.
  • Latching relays for ultra low power consumption
  • Battery operated 4 x 1.5V Alkaline AA (not included)
  • Built-in CAT port interface. CAT thru port for computer connection. 38400 baud.
  • 2000 memories when used with FT-817 interface (200 memories for other radios)
  • 1.8 to 54 MHz coverage (continuous coverage for MARS)
  • Tunes 6 to 600 ohms (about 10:1 SWR range). 16 to 150 on 6M (about 3:1)
  • SO-239 in and out connections for dipoles, verticals, beams, G5RV, OCF, Cobra, ect.

Dimensions: 5.1”L,  4.7”W, 1.7”H. Weight: 9.3 ounces (without batteries).

Includes 1 foot CAT cable.

Try Scotch All Weather Fasteners to attach the Z-817 to the radio.

This Tuner is a great pair to our X1M HF QRP radio, though a power cable would have to be made up to power this unit (or modify the existing cable)

LDG’s popular Z-100 economy tuner is now the Z-100Plus. Still small and simple to use, the Z-100Plus sports 2000 memories that store both frequency and tuning parameters. It will run on any voltage source from 7 to 18 volts; six AA batteries will run it for a year of normal use. Current draw while tuning is less than 100ma.

The Z-100Plus now includes an internal frequency counter so the operating frequency is stored with tuning parameters to make memory tunes a blazingly fast 0.1 seconds; full tunes take an average of only 6 seconds.

  • RF Power: 0.1 to 125 watts SSB and CW, 30W on PSK.
  • Latching relays for ultra low power consumption
  • 2000 memories sorted by frequency.
  • 1.8 to 54 MHz coverage (continuous coverage for MARS)
  • Tunes 6 to 800 ohms. (16 to 150 on 6M)
  • SO-239 in and out connections for dipoles, verticals, beams, G5RV, OCF, Cobra, ect.
