HC-1500AT
1
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 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.

• 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, HC-1500AT 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.
