ACOM 1000 HF + 6 Meter Linear Amplifiers

ACOM 1000 HF + 6 Meter Linear Amplifiers are the world's best value in an Amateur HF amplifier. These amps provide you a comfortable 1,000 watts output on all amateur bands from 160 through 6 meters.

The plate-load True Resistance Indicator (TRI) is a powerful tuning aid which helps the operator to quickly and precisely match antennas. The auto-operate function (when enabled) maintains the amplifier in OPERATE mode for you, saving on manual operations. Broadband input matches to the transceiver over the entire range of 1.8-54 MHz.

ACOM 1000 amplifiers are both user-friendly and look after themselves. They are designed to safely withstand up to 300 watts reflected power, drive spikes of up to 100 milliseconds duration, drive RF "tails" after a PTT or KEY release and the operator's inadvertent tuning errors. They also withstand a "soft" AC line and will deliver more than half power at only 75 percent of nominal mains voltage. They can withstand voltage drops for up to 10 milliseconds, and up to 15 percent higher line-voltage spikes. These details are all important, particularly when used at Field Day, on DXpeditions and other portable operations. Be sure to read the SPECIAL Note, below.

An ACOM 4CX800A high-performance ceramic/metal tetrode with plate dissipation of 800 watts is employed. On-board processing provides permanent monitoring and protection of plate and grid voltages and currents, as well as the exhaust temperature.

Text messages, 12 different parameters, and strip peak-reading PEP meter are displayed on a dot-matrix, back-lighted LCD. LED indicators are provided for OPERATE, attenuator-on, and ON/OFF conditions. Records of the amplifier internal status are stored in nonvolatile memory for the seven most-recent auto-protection trips. This information is very valuable should diagnostics be needed.

The input bypassing and the vacuum antenna relays are very quiet even in CW mode due to their special mounting. This results in virtually noise-free QSK!
