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 Tuner Needed
No heavy outboard antenna tuners required for antenna VSWRs up to about 3:1. ACOM 1500 will enable the operator to change antennas virtually instantaneously and allow the operator to use his or her antennas over wider frequency ranges.

User Friendly Amplifier
ACOM 1500 is the 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, and operator’s inadvertent tuning errors etc. ACOM 1500 also will not cease to function with a “soft” AC mains and will deliver more than a half power at only 85% of nominal mains voltage. ACOM 1500 can withstand voltage drops (down to zero Volts) for up to 10 milliseconds and can tolerate 15% mains voltage spikes, which is especially important during field day, during DXpeditions, and at portable operating events where emergency power is relied upon.

VFD Comment Display
All amplifier status indications are indicated on the dot matrix, high brightness vacuum fluorescent display (VFD). The upper line on the VFD always demonstrates the peak forward output power.  LED indicators are provided for:  OPERATE mode, attenuation-on, transmit, selected antenna output, and ON/OFF conditions.

Three Antenna Output Ports
Three antenna outputs are selectable using a push-button on the front panel of the amplifier.

Easy maintenance
Data regarding ACOM 1500 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 a very good load to the transceiver over the entire spectrum of 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.
