mAT-TUNER mAT-10
A compact 1.8–54MHz automatic antenna tuner designed especially for the Yaesu FT-817 and FT-818, with convenient one-touch tuning, 16,000 memories and built-in USB-C rechargeable power.
The mAT-10 is a small, portable automatic antenna tuner designed primarily for the Yaesu FT-817 and FT-818. When connected using the supplied mAT-CY control cable, the tuner communicates with the radio through its ACC port to provide simple one-key automatic tuning.
It can also be used as a general-purpose tuner with other low-power QRP transceivers. In this mode no control cable is required – simply connect the radio and antenna using suitable coaxial leads and start the tuning cycle from the front-panel button.
One-Touch Automatic Tuning
Connect the mAT-10 to the FT-817 or FT-818 ACC socket using the supplied mAT-CY cable and the tuner can communicate directly with the transceiver.
Press and hold the mAT-10's multifunction button to begin tuning. The tuner automatically controls the radio during the tuning cycle and returns it to normal operation when matching is complete.
Use It as a Universal QRP Tuner
With other low-power transceivers, the mAT-10 can operate without the control cable. Connect the transceiver to the RADIO socket, connect the antenna to the ANT socket and start a manual tuning cycle using the front-panel multifunction button.
SWR & Battery Indicators
Three upper LEDs provide an at-a-glance indication of SWR while operating. With the tuner switched off, briefly pressing the multifunction button uses the same LEDs to indicate the approximate battery charge level.
One Multifunction Button
A single front-panel control handles power, starting a tuning cycle, checking battery level and switching between Online and Bypass modes. Additional LEDs indicate Online/Bypass, tuning status and power.
Learns as You Use It
The mAT-10 can store matching information for up to 16,000 frequencies. When you return to a previously tuned frequency, Memory Tune can rapidly recall the stored matching settings.
If no suitable memory is available, the tuner performs a full tuning cycle and stores the resulting settings for future use.
Recharge from USB-C
Two internal 10440 rechargeable lithium batteries power the tuner, removing the need for a separate DC supply during normal operation.
The current mAT-10 uses a standard USB-C charging connection and is supplied with a USB-C charging cable, so a proprietary mains charger is no longer required.
Connect the tuner to a USB-C power source before first use to activate the internal battery protection circuit. The same procedure should be followed after replacing the internal batteries.
Built for Portable QRP
The compact enclosure is CNC-machined from aluminium and finished in black, creating a small and robust tuner particularly well suited to portable FT-817 and FT-818 installations.
