Acom - 1500HF + 6M Linear Amplifier

Technische ficheHandleiding

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 tuners

No heavy outboard antenna tuners required for antenna VSWRs 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.


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.         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.

Three antenna outputs

Three antenna outputs are selectable using a push-button on the front panel.

Easy maintenance

Data   regarding   amplifier   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 very good load to the transceiver over the entire spectrum 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.
