ACOM - 1010 - HF TUBE TYPE LINEAR AMPLIFIER OPERATING FROM 1.8 TO 29.7 MHz - 500 WATT CONTINUOUS KEYED CARRIER OR 700 W P.E.P.


DESCRIPTION

The ACOM 1010 HF Linear Amplifier is the world's best value in an amateur HF amplifier. The ACOM 1010 gives you a comfortable 500 WATT CONTINUOUS KEYED CARRIER OR 700 W P.E.P. output on all amateur bands from 160 through 10 meters.
 
Easy to operate
The 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.

No antenna tuners
The amplifier will perform the functions of an antenna tuner for VSWR up to 3:1, thus enabling you change antennas faster and use them over a wider frequency range (saving tuning time).

User-friendly
An amplifier that is both user-friendly, and that looks after itself. It is designed to safely withstand up to 240W 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 - important particularly when used at field days, Dxpeditions, etc.

LED bar-graph display.
The upper LED bar-graph always reads peak forward power while the lower LED bar-graph is for the reflected power. LED warning indicators are provided for abnormal conditions of grid 1, grid 2, and plate parameters.

Antenna selection.
Two antenna outputs are selectable on the front panel of the amplifier.

Transceiver-independent.
The amplifier operates without special signaling from the transceiver; it needs only “ground on TX” and 60 W RF drive power to operate at full output power.

Broadband input matching
Resulting in very good load to the transceiver over the entire spectrum 1.8-29.7MHz.

Single 4CX800A (GU74B)
A Svetlana high performance ceramic-metal tetrode with plate dissipation of 800W is employed (forced air cooling, grid-driven).

Tube protection
Permanent monitoring and protection of plate and grid voltages and currents.
