ACOM 1500 HF and 6m LINEAR AMPLIFIER
Easy to
operate
The TRI
is a powerful tuning aid that, together with the
automatically
controlled input attenuator, helps the operator to quickly and precisely match
the antenna impedance to the optimum tube load impedance (5-10 seconds
typically). The auto-operate function (when enabled) maintains the amplifier in
the OPERATE mode for you, thus avoiding unnecessary manual operations.
No
antenna tuners
No heavy
outboard antenna tuners required for antenna
VSWRs up
to about 3:1. Your amplifier will enable
you to change antennas virtually instantaneously and allow you to use your
antennas over wider frequency ranges.
User-friendly
An amplifier
that is both
user-friendly and that
looks
after
itself. It is designed to safely
withstand up to 300W reflected power, up to 100 milliseconds duration of drive
spikes, drive RF “tails” after a PTT or KEY release, operator’s inadvertent
tuning errors etc. The amplifier also
will not cease to function with a “soft” AC mains and will deliver more than
half power at only 85% of nominal mains voltage. It can withstand voltage drops
(down to zero Volts) for up to 10 milliseconds and can tolerate 15% mains
voltage spikes, which is especially important on Field Day, during DXpeditions,
and at portable operating events where emergency power is relied upon.
VFD
comment display
All
amplifier status indications are explained via detailed
text
displayed on the dot matrix, high brightness vacuum
fluorescent
display (VFD). The upper line on the VFD
always reads peak forward power. LED
indicators are provided for: OPERATE
mode, attenuation-on, transmit, selected antenna output , and ON/OFF
conditions.
Three
antenna outputs
Three
antenna outputs are selectable using a push-button
on the
front panel.
Easy
maintenance
Data regarding
amplifier internal status
is stored in a
nonvolatile
memory for 7 of the most recent auto protection trips. This information can be
forwarded to your dealer for diagnostics.
Virtually
silent QSK
The input
bypassing and vacuum
antenna relays are
virtually silent
even in the CW QSK
mode thanks to
specially
designed mounting hardware.
Broadband
input matching
Resulting
in very good load to the transceiver over the
entire
spectrum 1.8-54MHz.
Single
4CX1000A tube
Uses a
ceramic and metal radial beam tetrode with plate
dissipation
of 1000 W which is specially designed for class
AB1 RF
linear amplifier operation.
Tube
protection
Permanent
monitoring and protection of plate and grid
voltages and
currents, as well
as of the
exhaust air
temperature.
