Informationen:
                                    The FL-70(H) is a microprocessor-controlled, all solid state
linear amplifier with built-in power supply and automatic
antenna tuner, providing up to 1.2 kilowatts RF input power
on the 160- through 10-meter HF amateur radio bands,
including the WARC bands.* Super-fast transmit/receive
turnaround timing allows the FL-7000 to be used for QSK CW,
HF packet radio and even AMTOR with an exciter so designed.
Requiring only 70 watts of excitation for full output, four
transistors with 300-watt collector dissipation each are
combined in a fully protected push-pull parallel wideband
“no-tune" amplifier circuit, powered by a heavy duty
regulated 47-V, 25-A DC power supply and cooled by a bottom
mounted fan through Yaesu's own “DVC" (Direct Vertical
Cooling) heatsinking system (patent pending). A high-power,
low loss automatic internal antenna tuner automatically
rematches the antenna whenever SWR exceeds 2:1,

Band changes are also completely automatic when the FL-7000
is used with Yaesu transceivers equipped with digital band
data output, such as the FT-747GX, FT-757GX(II), PT-767C.X,
FT-990 and FT-1000. When changing bands, previously stored
antenna selection and tuner setting are recalled from
lithium-backed memories automatically; transmission and
retuning arc not required. When rematching to a new load,
the power amplifier section automatically turns off until
the antenna has been matched.

Six different parameters in the amplifier, power supply and
tuner are simultaneously monitored by the protective
circuitry to avoid distortion of the rf output as well as to
protect the components: collector current, driving power
from exciter, temperature of amplifier and regulator
heatsinks, VSWR at output, push-pull circuit balance and ALC
voltage fed back to exciter. Dual 2 speed cooling fans
are-controlled with independent thermal sensors, for the
amplifier and power supply. Two large, clearly lit meters
provide constant monitoring of amplifier current
concurrently with either relative power output, supply
voltage, automatic VSWR or ALC, Flight LEDs on the front
panel inform the operator of tuner and protection system
status, including fan activity and high/low speed.
Additional LEDs indicate the selected band and antenna. Up
to four different antennas can be connected and
automatically selected by the FL-7000’s microprocessor for
different bands when the optional FAS-1-4R remote antenna
relay unit is used.

Without costly vacuum tubes there is no need fur a dangerous
high-voltage supply in the FL-7000, eliminating the problems
of tube and high voltage component failures. However, should
your FL-7000 ever need realignment, it has been designed
with every alignment point easily accessible by simply
removing the top cover.
