Acom 1000 - Valve Amp 160-6m 1kWThe plate-load True Resistance Indicator (TRI) 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.


The amplifier will perform the functions of an antenna tuner for VSWR up to 3:1, thus enabling you to change antennas faster and use them over a wider frequency range (saving tuning time).

An 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, 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. Withstands up to 10 milliseconds (down to zero) voltage drops, and up to +15% line voltage spikes.Acom 1000 - Valve Amp 160-6m 1kW

Text messages, 12 parameters, and strip peak-reading PEP meter displayed on a dot-matrix, back-lighted LCD. LED indicators are provided for OPERATE, attenuator-on, and ON/OFF conditions. The input bypassing and the vacuum antenna relays are very quiet even in CW mode due to their special mounting.

Complies with CE safety and EMC requirements, as well as FCC regulations (6, 10 & 12 m bands lock provided).
