ACOM 1000 current model

The ACOM 1000 is a complete and self-contained linear amplifier that covers all amateur bands from 1.8 through 54 MHz and provides over 1000 W output power with less than 60 W exciter drive.

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 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 tuner needed
No heavy outboard antenna tuners required for antenna SWR up to 3:1 (and higher on some bands). Your amplifier will perform the functions of an antenna tuner, thus enabling you to change antennas faster and use them over a wider frequency range (saving tuning time).

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. 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. It would withstand up to 10 milliseconds (down to zero) voltage drops, and up to +15% line voltage spikes, which is important particularly when used at field days, DXpeditions, and other portable events.
