1. GENERAL INFORMATION

1-1. Introduction and Description

This manual explains the installation, operation and maintenance of the ACOM2000A automatic HF
linear amplifier.
The ACOM2000A is a complete and self-contained linear amplifier which covers all amateur bands
from 1.8 through 30MHz, has automatic self-tune capability, and provides up to 1500W output power
with less than 60W exciter drive. In addition, it has automatic antenna impedance matching capability
for loads up to 3:1 VSWR (2:1 on 160 meters). It features a Remote Control Unit (RCU), contains
nonvolatile memory for settings on up to ten different antennas per frequency segment, and offers
command capability for use with an external automatic antenna selector and/or automatic antenna
tuner. Transmit / receive switching is capable of full break-in operation (QSK) via an internal vacuum
relay.
All indicators and controls (except the primary mains switch and indicator) are available via the RCU.
All command input to the RCU is menu-driven.
