Antenna selection. Two antenna outputs are selectable on the front panel of the amplifier.



Efficient tuning. Antenna matching can be achieved in less than 10 seconds and at a quarter of nominal



output power, which produces lower risk of interference to other stations and greater safety to the

amplifier components.

Transceiver-independent. The amplifier operates without special signaling from the transceiver; it



needs only "ground on TX" and 60 W RF drive power to operate at full output power.

Input matching. Broadband input matching circuitry offers excellent loading characteristics for the



driving transceiver, from 1.8MHz to 30MHz.

Reliable tubes. Two 4CX250B (7203) ceramic-metal tetrodes with a total plate dissipation of 500W



(forced air cooling, grid-driven) are used for maximum efficiency.

Short warm-up period. Only 30 seconds warmup period is required.



Permanent monitoring and protection of the plate and grid currents. The Bias Optimizer minimizes



heat dissipated by the tubes, assuring tubes longevity.

High voltage protection. Design of the high-voltage power supply eliminates the danger of turn-on



transients affecting sensitive devices connected to the same line (mains) circuit. Moreover, the amplifier can

be configured to accommodate any of 8 nominal line voltages between 100 and 240 V, 50 or 60 Hz.

Band inclusion. The amplifier can be shipped with 10 and 12-meter capability disabled as required by



the Federal Communications Commission (FCC), for United States users. Contact your dealer about

enabling those bands.

1-5. Safety Considerations, Explicit Definitions

The ACOM1011 HF Linear Amplifier is a Safety Class I unit. The grounding lead (yellow with 2 green

stripes) of the power cable and the ground stud on the rear panel of the amplifier (marked GND) must

be connected to the station's grounding system for safe operation. The amplifier is designed to meet

international safety standards and complies with CE safety and electromagnetic compatibility requirements,

as well as FCC regulations. This operating manual contains an assortment of precautions and warnings

that MUST BE FOLLOWED BY THE USER to ensure safe operation of the amplifier.

The safety definitions below apply to this operating manual:

WARNING

is associated with a procedure that, if not properly performed, could result in a fire hazard

or electric shock, with resulting injury or death to the user.

A CAUTION is associated with a procedure that, if not properly performed, could result in damage to

the amplifier or other equipment.

A NOTE is associated with a procedure that, if not properly performed, could result in inconvenience

or physical injury to the user.
