1. Forward Thank you for purchasing Tokyo Hy-Power model, automatic antenna tuner. is a compact HF/50MHz band high power auto antenna tuner with a maximum power handling capability of 1.5kW. The tuner fully intergrates with Tokyo Hy-Power Linear amps such as HL-1.5KFX, HL-2.5KFX, HL-2500FX etc. It is also designed to work with other linear amplifiers as well, due to the newly THP developed band decoding technology. It boasts of an extremely fast tuning speed of 1 sec. max. in most cases. When the transmitter is keyed, the tuner detects the antenna impedance (resistance and reactance) directly, and the two variable capacitors are auto-adjusted so that tuner matches the antenna impedance. 2. Features High speed and precision tuning due to the high resolution stepping motors driven by the microprocessor: The typical tuning time is less than one second, with the exception on the 160m band. On this band, the typical tuning time is 3sec. Simple operation: Auto tunes even with ssb/voice as well as keyed codes. During the auto-tuning time period the linear amp is held at STBY (stand-by), and then automatically switches to OPER. (operate) as soon as the tuning is completed. Tuning position data is stored in the memory with respects to frequency, band segment and antenna port. As a result re-tuning is extremely fast, When tuning up and down the bands. With the newly developed band decoder, is compatible with frequency band information sent from such radio s as ICOM, YAESU and KENWOOD, and can follow the radio as you move within the band. Furthermore the tuner can select the operating band independently through the built-in frequency counter. The tuner is equipped with two data ports of IN and OUT for a series expandable serial interface. With this feature, the band data from the transceiver can be transferred to the linear amp by way of the tuner. 1

3. Cautions Note the followings for the safety of the operator. A If any smoke, odor, or fire is detected, take the following steps for safety. 1 Cease the transmission. 2 Turn off the power of linear amp and radio. 3 Turn off the power of tuner. B High RF Voltage A high RF Voltage is generated during the transmission period. Never remove the top cover. Never operate without connecting an antenna. Never touch RF connectors. Be careful of the tuner cabinet as it may bear RF voltage depending on the antenna type connected. Those operators with heart pacemakers must not approach the tuner. Avoid the risk of RF burn from a high SWR antenna on its element length. Never touch cooling fan inside as well as L, C components, as they generate much heat during operation. C Limited Application This tuner is designed for the use of the amateur radio station operated by qualified operator. Application for other than designed purpose leads to the failure of the device and/or the severe damage to the surrounding devices. Never exceed the maximum handling power of 1.5kW. D Setting Internal parts such as tuning coils and motors are forced air cooled and need air ventilations. Keep at least a few inches of space from the rear wall, and a space of rubber feet height at the bottom. Keep out of direct sun light, in a clean dry environment. E Power Derating for high SWR Antenna When the antenna has high SWR of 3 to 4, reduce RF output power by at least a half not to damage the tuning components. Also never attempt to tune to very high SWR antenna, even if the tuner happens to work, or the tuning relays and capacitors as well as coax cable will be severely heated and damaged. F Power ON Sequence It is recommended to turn on the transceiver first, then the amplifier, and finally the auto tuner. G Power Off/Thru When the POWER switch is turned off, ANT1 port is the default bypass antenna port. H Tube Linear Amp Combination with tube type linear makes plate tuning circuit and tuner network connected in a cascade way. As they mutually affect each other, note the following tuning procedure. 1 Tune the amp with 50Ω dummy load first. Then, tune the tuner with linear amp in STBY (off) mode. 2 Alternatively turn the tuner, first, with amplifier in STBY (off), and then tune the linear for maximum power output. 2

4-1. Equipment Needed for an Operation A. DC Power Supply DC12V (11 14V), 2A (negative ground) B. Coax Cable RG8U or higher grade is recommended. RG8X and similar small diameter coax is not recommended. C. Transceiver HF/50MHz radio that delivers at least 50W of output power, that drivers the tuner directly when tuning. The radio with output power reduction feature is preferred when there is high reflected power. D. Linear Amp The Linear amp of 1 to 1.5kW output with ALC feedback is preferred. Avoid the one with over-shoot/ spiking. E. Antenna Antenna should have power handling capacity of 1,500W or more, and relatively low SWR. Even if the high SWR is lowered with the tuner, it will make the coax cables heated, and cause interferences around the vicinity. F. Band Cable Band cables for the respective radios are available as optional parts for the smooth and comfortable operation. Please note that full break-in CW is not available when the band data cable is not used. (See 11, Connection/ Operation. Page 14 19.) G. ISO Screw Bolts This tuner uses ISO std. screws. 3
