8. Push and hold the TUNE button on the front of the Z-817 for one second (until the Tuning
LED comes on), then release. The transceiver automatically switches to PKT mode, and keys up
with a minimal amount of power, and the Z-817 begins a tuning cycle. At the end of the tuning
cycle, the original mode and power level is restored.
9. Wait for the tuning cycle to end; you’re now ready to operate!
10. (Non-FT-817 Radios): Select operating frequency, and switch mode to CW or AM.
11. Key the radio, press and hold the TUNE button on the Z-817 until the Tuning LED comes
on, then release the TUNE button.
12. Wait for the tuning cycle to complete.
13. Un-key the radio, then return to the desired operating mode; you’re ready to operate!
SPECIFICATIONS
•
0.1 to 20 watts SSB, CW, and digital modes.
•
Latching relays for ultra low power operation.
•
2,000 memories for instantaneous frequency and band changing (when used with FT-817
radio. 200 memories otherwise.)
•
Battery powered. 4x 1.5V AA (Alkaline recommended for long life)
•
Designed specifically for the Yaesu FT-817 QRP HF transceiver.
•
Also works with any transceiver with maximum 20 watts power rating.
•
Pass-thru CAT port allows Z-817 to control the FT-817 over the CAT bus while still allowing
a host PC to also control the radio.
•
1.8 to 54.0 MHz coverage. Frequency for memory storage is read from the radio via CAT.
•

•
For Dipoles, Verticals, Vees, Beams or any Coax Fed Antenna.
•
Optional external Balun allows tuning of random length, long wire or ladder line fed antennas.
•
Dimensions: 5.1L” x 4.7W” x 1.7H”. Fits on top the FT-817 with room to spare, allowing
access to aftermarket add-ons such as internal DSP.
•
Weight: 9.3 ounces (without batteries)
AN IMPORTANT WORD ABOUT POWER LEVELS
The Z-817 is rated at 20 watts maximum power input at most. Many ham transmitters and
transceivers, and virtually all amplifiers, output well over 20 watts. Power levels that significantly
exceed specifications will definitely damage or destroy your Z-817. If your tuner fails during
overload, it could also damage your transmitter or transceiver. Be sure to observe the specified
power limitations.
