1.3. Equipment Supplied
The ACOM 1500 amplifier and this User's Manual are shipped in a cardboard carton.
1.4. Features
• Easy to operate
The TRI (True Resistance Indicator) is a powerful tuning aid which, 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 saving manual operations and
time.
• No antenna tuner needed
No heavy outboard antenna tuners required for antenna SWRs 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 and durable
An amplifier that is both user-friendly and that looks after itself. It is designed to safely withstand up
to 300 W 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.
• OLED comment display
All amplifier status indications are explained via detailed text displayed on the OLED (Organic Light
Emitting Diode) Display. The upper line on the OLED display always reads peak forward power. LED
indicators are provided for: OPERATE mode, attenuation-on (ATT), transmit (TX), selected antenna
output (1, 2, or 3), and ON/OFF conditions.
• Easy antenna selection
Three antenna outputs are selectable using a push-button on the front panel.
