The ACOM 1000 HF Linear
Amplifier is the world's best value in an amateur HF amplifier. The
ACOM 1000 gives you a comfortable 1000 watts output on all amateur
bands from 160 through 6 meters.
FEATURES
Easy to operate
The plate-load True Resistance Indicator
(TRI) is a powerful tuning aid which, together
with the automatically controlled input
attenuator, helps the operator to quickly and
precisely match antennas (5-10 seconds typically).
The auto-operate function (when enabled) maintains the amplifier in OPERATE mode
for you, thus saving manual operations and time.
No antenna tuners
The amplifier will perform the functions
of an antenna tuner for VSWR up to 3:1, thus enabling you change antennas faster and
use them over a wider frequency range (saving tuning time).
User-friendly
An amplifier that is both user-friendly, and
that looks after itself. It is designed to safely withstand up to 500W 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.
It would also not cease to function with a
"soft" AC line and would deliver more than
half power at only 75% of nominal mains voltage. Withstands up to 10 milliseconds (down
to zero) voltage drops, and up to +15% line voltage spikes - important particularly
when used at field days, Dxpeditions, etc.
LCD comment display
Text messages,12 parameters, and strip
peak-reading PEP meter displayed on a dot-matrix, back-lighted LCD. LED indicators
are provided for OPERATE, attenuator-on, and ON/OFF conditions.
Easy maintenance
Signatures of the amplifier internal status
are stored in a nonvolatile memory for 7 most recent auto protection trips. This
information is used for diagnostics.
Virtually silent QSK
The input bypassing and the vacuum
antenna relays are very quiet even in CW mode due to their special mounting.
Broadband input matching
Resulting in very good load to the
transceiver over the entire spectrum 1.8-54MHz.
Single 4CX800A (GU74B)
A Svetlana high performance
ceramic-metal tetrode with plate dissipation of 800W
is employed (forced air cooling, grid-driven).
Tube protection
Permanent monitoring and protection of
plate and grid voltages and currents, as well as
of the exhaust temperature.
