Introduction; Jumpstart, Or "Real Hams Don't Read Manuals - LDG KT-100 Operation Manual

INTRODUCTION

Congratulations on selecting the KT-100 100-watt automatic tuner for Kenwood transceivers.
The KT-100 provides automatic antenna tuning across the entire HF spectrum plus 6 meters, at
power levels up to 125 watts. It will tune dipoles, verticals, Yagis, or virtually any coax-fed
antenna. It will match an amazing range of antennas and impedances, far greater than some other
tuners you may have considered, including the built-in tuners on many Kenwood radios.
The KT-100 is similar to previous LDG tuners, but is specifically engineered to integrate
with your Kenwood HF radio. The KT-100 connects to the Kenwood AT-300 tuner port on the
back of the radio. Not only is the KT-100 controlled by the radio, it also is powered by the radio,
so there are no additional interface cables required to use the KT-100!

JUMPSTART, OR "REAL HAMS DON'T READ MANUALS!"

Ok, but at least read this one section before operating the KT-100:
Turn off power to your Kenwood radio.
Connect the antenna jack (Antenna "1" on TS-480) on your transceiver to the "TX" jack on the
KT-100, using a 50 ohm coax cable jumper.
Connect a 50 ohm coax antenna feedline to the "ANT" jack on the KT-100.
Connect the 6-pin end of the supplied radio interface cable to the Antenna Tuner port on the back
of your Kenwood radio.
Connect the 7-pin mini-DIN plug end of the supplied radio interface cable to the "Radio" jack on
the back of the KT-100
Turn on power to your transceiver and select the desired operating frequency and mode.
Push and hold the AT or TUNE button on the front of your transceiver for one second
transceiver automatically switches to CW mode, and keys up with a reduced amount of power,
and the KT-100 begins a tuning cycle. At the end of the tuning cycle, the original mode and
power level is restored.
Wait for the tuning cycle to end; you're now ready to operate!

Note: Tuning on the 6 meter band requires a different procedure; see the section on tuning on 6 meters.
