1. Turn off power to your radio. 2. Connect the antenna jack on the transceiver to the “Radio” jack on the optional RC-100. 3. Connect the “Tuner” jack of the optional RC-100 to the “Radio” jack on the RT-100 via a suitable length of coax feedline. -

• Weight: 1 lb. 0 oz. AN IMPORTANT WORD ABOUT POWER LEVELS The RT-100 is rated at 125 watts peak power input at most. Many ham transmitters and transceivers, and virtually all amplifiers, are capable of transmitting well over 125 watts. Power levels that significantly exceed specifications will definitely damage or destroy your RT-100. -

DC power; this process is virtually lossless and has no effect on SWR. A second Bias Tee is required at the transmitter end of the coax to inject DC power on to the coax. The RT-100 is designed to be used with the optional RC-100 controller, which contains a Bias Tee to inject DC power. - Page 6 Important Note: The transmission line between the Bias-Tee at the operating position (or the RC-100 control unit) and the RT-100 tuner must never be grounded. Doing so would cause the Bias-Tee to attempt to source 12 VDC directly to ground, damaging the unit. Never use coax switches that ground unselected ports.

Insert the threaded ends of the U-bolt through the back of the mounting bracket at the top of the RT-100. Thread the nuts back onto the U-bolt, and snug them up. Tighten only as much as is required to keep the RT-100 from sliding down the mast;... - Page 8 If upgrading an existing antenna, move the coax feedline from the antenna feedpoint to the RADIO jack on the RT-100. Connect a 50-ohm coax jumper (as short as practical) from the RT- 100’s ANT jack to the antenna’s feed point.
- Page 9 If necessary, pound a short mast into the ground near your antenna and mount the RT-100 to it as shown on page 7. LDG strongly recommends grounding the RT-100 tuner via the wingnut marked GND.

Page 10: Bias Tee Information
Downloaded from www.g7syw.com BIAS TEE INFORMATION The LDG RT-100 incorporates a Bias Tee in the tuner itself, but a second Bias Tee is needed at the transmitter end and is not included; you must supply one. The optional LDG RC-100 is an ideal companion to the RT-100, and includes a built-in Bias Tee designed specifically for the RT-100. -

Force a Full Tuning Cycle In some instances you may wish to force the RT-100 to begin a full tuning cycle instead of the usual memory cycle. Turn off power to the RT-100 by switching off power to the Bias Tee, begin transmitting a carrier, and while still keying the radio, turn on power to the Bias Tee;... -

• If using your own Bias-Tee, change bands, force a tune, then return to the desired band MARS/CAP Coverage The RT-100 provides continuous tuning coverage from 1.8 to 54.0 MHz, not just in the ham bands. This makes it useful for MARS or CAP operation, or any other legal HF operation. -
