Thank you for purchasing Tokyo Hy-Power model HC-1500AT, automatic antenna tuner.HC-1500AT is a compact HF/50MHz band high power auto antenna tuner with a maximumpower handling capability of 1.5kW. The tuner fully intergrates with Tokyo Hy-Power Linearamps 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 developedband decoding technology. It boasts of an extremely fast tuning speed of 1 sec. max. in mostcases. When the transmitter is keyed, the tuner detects the antenna impedance (resistanceand reactance) directly, and the two variable capacitors are auto-adjusted so that tunermatches the antenna impedance.
2. Features
1. Forward
• High speed and precision tuning due to the high resolution stepping motors driven by themicroprocessor: 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 thenautomatically 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 andantenna port. As a result re-tuning is extremely fast, When tuning up anddown the bands.
• With the newly developed band decoder, HC-1500AT is compatible with frequency bandinformation sent from such radio’s as ICOM, YAESU and KENWOOD, and can follow theradio as you move within the band.Furthermore the tuner can select the operating band independently through the built-infrequency counter.
• The tuner is equipped with two data ports of IN and OUT for a series expandable serialinterface. With this feature, the band data from the transceiver can be transferred to thelinear amp by way of the tuner.

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 VoltageA 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 typeconnected.
· 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 heatduring operation.
C Limited ApplicationThis tuner is designed for the use of the amateur radio station operated by qualifiedoperator. Application for other than designed purpose leads to the failure of the deviceand/or the severe damage to the surrounding devices. Never exceed the maximumhandling power of 1.5kW.
D SettingInternal parts such as tuning coils and motors are forced air cooled and need airventilations. Keep at least a few inches of space from the rear wall, and a space of rubberfeet height at the bottom. Keep out of direct sun light, in a clean dry environment.
E Power Derating for high SWR AntennaWhen the antenna has high SWR of 3 to 4, reduce RF output power by at least a half notto 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 anddamaged.
F Power ON SequenceIt is recommended to turn on the transceiver first, then the amplifier, and finally the autotuner.
G Power Off/ThruWhen the POWER switch is turned off, ANT1 port is the default bypass antenna port.
H Tube Linear AmpCombination with tube type linear makes plate tuning circuit and tuner network connectedin 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.

4-1. Equipment Needed for an Operation
A. DC Power SupplyDC12V (11 – 14V), 2A (negative ground)
B. Coax CableRG8U or higher grade is recommended. RG8X and similar small diameter coax is notrecommended.
C. TransceiverHF/50MHz radio that delivers at least 50W of output power, that drivers the tuner directlywhen tuning. The radio with output power reduction feature is preferred when there is highreflected power.
D. Linear AmpThe Linear amp of 1 to 1.5kW output with ALC feedback is preferred. Avoid the one withover-shoot/ spiking.
E. AntennaAntenna 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, andcause interferences around the vicinity.
F. Band CableBand cables for the respective radios are available as optional parts for the smooth andcomfortable operation. Please note that full break-in CW is not available when the band datacable is not used.(See 11, Connection/ Operation. Page 14 – 19.)
G. ISO Screw BoltsThis tuner uses ISO std. screws.

Any antenna port can be programmed for a particular band.
Once programmed, the data remains in memory until it is re-programmed.
C. Band Data
As a means of band data transfer, following interfaces are available for HC-1500AT.
·CIV: ICOM’s CI-V interface. As 1 KHz order data is carried, band data is transferredinstantaneously making quick QSY’s possible
·KEN: KENWOOD’s interface of EIA-232C serial. Also handles detailed data.
·YAE: YAESU’s 4 bit band data. Since only the band data is carried it needs a supplementaryfreq. data for low bands.
·THP: The mode to connect to TUNER terminal of THP linear amps. (PWM hand-shake.)
·FRQ: Frequency measuring mode through the built-in frequency counter. Needs one push ofbutton to start up.
·NON: NON interface. Completely manual setting mode.
A. For Amateur Service
HC-1500 is strictly for amateur radio use only.
Operation outside the amateur bands operation is not recommended and couldwill cause the tuner to malfunction.

Re-tuning
While transmitting, or tuner is in operation,you can decrease the increased reflectedpower by pressing ENTRY button.
SWR Bar-graph
With the LED bar-graph, you canrecognize the tuning status visually. Graphshows a SWR at transceiver (or linear)output point, and not a reflected power.
When auto tuning is completed, all LEDswill go off. At time possibly one green LEDcould remain lighted.
Note
When tuning in frequency counter mode, re-tuning may take slightly longer time. For thefrequency counter has to acquire theoperating frequency.

connected to the linear (or x-ceiver) andthe antenna.
You need to select and set either TRU1,TRU2, or TRU3, predicated on whichantenna port you have selected for thatparticular band.
It is a useful function when testing linearwith dummy load, or when TX/RXfrequency is much different each other(split QSO).
This bypass (Thru) setting is required foreach band respectively.

13. About Memory
Programmed data parameters are stored in the non-volatile IC memory.
With the stored data, capacitors (C1 and C2) are preset accordingly, next time the tuner is operated.
Operating Status Memory (RESUME Memory)
Memory and Status is stored when the tuner powered is off, and recalledagain when power is turned back on.
They are, Band (Freq.), Tuning Position (C1, C2), Antenna Port, and
, Interface Setting.
* If the transceiver setting has been changed after the power is turned on,
the tuner settings will be changed accordingly.
Setting Status Memory
Various parameters which are selected for each band are memorized for that bandrespectively
Memory Contents

Default
Each band defaults to ANT1 port

Note
Since only one antenna is memorized per band, it is impossible to select more than oneAnt port per band.

Warning Sign
This tuner can tune to relatively high SWR antenna successfully.
In such a case, reduction of running power is recommended to approx. 500W, due tothe excessive current applied to the internal components.

Tuning Range
Network circuitry of HC-1500AT is a T-shapedmatching network.
Although T-shape can match relatively wideimpedance range of the load, it creates anextremely high RF voltage and current, if L andC values are not appropriate.
HC-1500AT uses proper L and C values only,for each band.

All tuning data are stored in the IC memory. However, for some reason, there is a chance that databecame corrupted. In such a case, memory can be re-written to default condition at time of factoryshipment. This is called “All Reset” and operation procedure is as follows.
(1) At first, turn the power off.
