U20447 Used LDG Electronics Z-817 Autotuner QRP Automatic Antenna Tuner

U20447 Used LDG Electronics Z-817 Autotuner QRP Automatic Antenna Tuner

Overall Condition: Used, great physical and operational condition overall showing only light handling! Cosmetic Details: The lightweight black composite chassis is clean and solid, presenting only minor superficial handling scuffs from portable station use. Front Panel & Controls: The single-touch Tune push-button and dual SWR / Tuning status LEDs are crisp, fully intact, and responsive. Rear Panel & Ports: Rear SO-239 antenna (Ant) and transmitter (Tx) coaxial ports feature clean, bright nickel-plated threads and pristine white dielectric insulators. The wing-nut ground stud (Gnd) and dual 8-pin mini-DIN radio interface/CAT pass-through ports are undamaged and corrosion-free. Note: listing is tuner only. No Cables included

The LDG Z-817 is an ultra-compact, microprocessor-controlled automatic antenna tuner designed specifically for QRP portable transceivers, integrating seamlessly with the Yaesu FT-817, FT-817ND, and FT-818 series. Powered internally by four standard AA batteries (not included), it uses latching relays that draw zero current while idling, making it exceptionally battery-friendly for field operations, SOTA, POTA, and backpacking.

Covering 160 through 6 Meters (1.8 to 54 MHz) with a power rating of 0.1 to 20 Watts (SSB/CW), the Z-817 matches dipole, vertical, beam, and random wire antennas over a 6 to 800 $\Omega$ impedance range (16 to 150 $\Omega$ on 6M). With 2,000 frequency memories, it recalls previously tuned settings in less than 0.1 seconds, delivering fast, one-touch tuning wherever you operate in the field.

Condition Breakdown

• General: Pre-owned, great functional and aesthetic condition with minimal handling wear

• Enclosure State: Durable molded composite casing is structurally intact with faint surface handling scuffs

• Front Controls: Front tactile Tune button clicks positively; green SWR and red Tuning LEDs are clean and clear

• Rear Connectors: Dual SO-239 coaxial jacks (Ant and Tx), wing-nut chassis ground post, and dual mini-DIN interface/CAT pass-through jacks are firm and corrosion-free

• Portability: Built-in internal battery compartment eliminates the need for bulky external power cables in the field (batteries not included)

Key Features

• 1.8 to 54 MHz QRP Coverage: Full coverage across HF (160M–10M) plus the 6-Meter amateur band

• 0.1W to 20W Power Rating: Optimized for QRP operation with a 20-Watt SSB/CW rating (5W on continuous digital modes)

• Tailored for Yaesu FT-817/818: Direct CAT-controlled tuning interface changes mode to carrier, drops power, tunes, and restores original operating mode automatically

• 2,000 Frequency Memories: Remembers LC tuning configurations across bands for lightning-fast band switching

• Ultra-Low Battery Consumption: Latching relays retain tuned configurations indefinitely with virtually zero standby current draw

• Wide Matching Range: Tunes loads ranging from 6 to 800 Ohms (approx. 10:1 SWR)
