comes on), then release. The transceiver automatically switches to AM mode, reduces power, and keys
up, and the YT-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!
SPECIFICATIONS
0.1 to 125 watts SSB and CW peak power, 100W on digital modes and 6 meters.
Latching relays for ultra low power operation.
2,000 memories for instantaneous frequency and band changing.
Powered from the radio -- no extra power supply to hook up.
Designed specifically for the Yaesu FT-100/FT-100D/FT-857/FT-857D/FT-897/FT-897D HF
transceivers.
Pass-thru CAT port allows YT-100 to control the radio over the CAT bus while still allowing a
host PC to also control the radio. 4800 Baud.
Pass-thru CAT port waits for idle CAT activity before controlling the transceiver.
1.8 to 54.0 MHz coverage. Frequency for memory storage is read from the radio via CAT.
Tunes 4 to 800 ohm loads (16 to 150 on 6M), 16 to 3200 ohms with optional 4:1 Balun.
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: 8.0”L x 7.6”W x 1.8”H.
Weight: 1.5 pounds
AN IMPORTANT WORD ABOUT POWER LEVELS
The YT-100 is rated at 125 watts maximum power input
at most.
Many ham transmitters and
transceivers, and virtually all amplifiers, output well over 125 watts. Power levels that significantly
exceed specifications will definitely damage or destroy your YT-100. If your tuner fails during overload,
it could also damage your transmitter or transceiver. Be sure to observe the specified power limitations.
IMPORTANT SAFETY WARNING
Never install antennas or transmission lines over or near power lines. You can be seriously
injured or killed if any part of the antenna, support or transmission line touches a power line.
Always follow this antenna safety rule: the distance to the nearest power line should be at least
twice the length of the longest antenna, transmission line or support dimension.
