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!

ACOM 1010 HF Linear Amplifiers
ACOM 1010 HF Linear Amplifiers cover all bands from 1.8 through 29.7 MHz. They provide over 700 W PEP output (or 500 W continuous-modes) with less than 60 watts of drive and operate without special transceiver signaling; they need only "ground on TX" and the required drive. ACOM's exclusive True Resistance Indicator (TRI); enables faster antenna changes and use over wider frequency ranges. Also, a built-in antenna selector switch with two outputs is included to provide instant choice of antennas. Antenna matching can be achieved in less than 10 seconds and at a quarter of nominal output power, which results in lower risk of interference to other stations and greater safety to the amplifier components. A single ACOM 4CX800A high-performance ceramic-metal tetrode with plate dissipation of 800 watts is used for maximum efficiency. These amplifiers are self-monitoring. They are designed to safely withstand up to 240 watts of reflected power, up to 100 milliseconds of drive spikes (RF "tails" after a PTT or KEY release), and even operator tuning errors. They are also capable of operating at more than half their designed output at only 75 percent of nominal line voltage. Because they can tolerate deep voltage drops and 15 percent line voltage spikes, they are particularly well-suited for use in portable environments, such as Field Day and DXpeditions. Importantly, a variety of system parameters are continuously monitored and available to the operator to assure safe and efficient amplifier operation. Design of the high-voltage power supply eliminates the danger of turn-on transients affecting sensitive devices connected to the same line (mains) circuit. Moreover, the amplifier can be configured to accommodate any of eight nominal line voltages between 100 and 240 V, 50 or 60 Hz. Please see the SPECIAL Note, below. ACOM 1010 specifications: * Frequency Coverage: All amateur bands in the 1.8-29.7MHz frequency range * Power Output: 700 W PEP or 500 W continuous modes. * Intermodulation Distortion: Better than 35 dB below rated output. * Hum and noise: Better than 40 dB below rated output. * Harmonic Output Suppression: Better than 50 dB below rated output. * Input and Output Impedance: Output: 50 Ohm unbalanced, SO-239 connectors; Input circuit: broadband, VSWR less than 1.3:1, 1.8-30 MHz continuously (no tuning, no switching); Bypass path: VSWR less than 1.1:1, 1.8-30 MHz continuously, 200 W maximum * RF Gain: 11dB, frequency response less than 1dB (50 to 70 W drive for rated output) * AC Power: 85-132 V/170-264 V ac (100, 110, 120, 200, 210, 220, 230 & 240 V nominal taps, plus 10 percent to minus 15 percent tolerance), 50-60 Hz, single phase, 1,200 VA * SPECIAL Note: Order part number AOM-1010 to wire your AC plug after removing European plug yourself; order part number AOM-1010-240 for pre-wired 240 volt operation (NEMA 6-15P) or part number AOM-1010-120 for pre-wired 120 volt operation (NEMA 5-15P). * Operating environments: Temperature range; 32 to 122 degrees F, Humidity; up to 95 percent at 95 degrees F, Altitude; up to 10,000 above sea level without output deterioration. * Complies with FCC-regulations as well as CE safety and electromagnetic compatibility requirements * Dimensions, (in.) 15.83 W x 12.4 D x 6.5 H * Weight: 39.7 lbs.

ACOM 700S Solid State 1.8-54 MHz Linear Amplifiers
ACOM 700S Solid State 1.8-54 MHz Linear Amplifiers are state-of-the art amplifiers that cover all amateur bands from 160 through 6 Meters. These amps provide 700 W output power (PEP SSB or CW modes). Working parameters of the amplifier are indicated on a multi-function, high-resolution 5 inch color display. Amplifier control is accomplished with only six buttons on the front panel or directly by CAT interface from the transceiver or remotely by RS232 interface. ACOM 700S amplifiers are compatible with all transceiver models available on the market. The broadband input matches to the transceiver with low SWR over the entire range of 1.8-54 MHz. Full output operation only requires a maximum of 40 watts drive and the typical "ground on transmit" (PTT) keying with no special signals required. The overall operation of ACOM 700S amplifiers is extremely simplified. Screen menus are intuitive and easy to follow and no special skill is required from the operator when changing frequency bands. The amplifier monitors the frequency of the input signal through the built-in frequency counter and automatically switches bands. A band data or CAT interface connection from the transceiver is NOT required for automatic band changing. These amplifiers take care of themselves during operation, due to the continuously-working protection circuits in all modes. The operator can digitally monitor more than 10 parameters concerning the working conditions of the amplifier. Detailed data (55 parameters) about each of the last 28 hard-fault protection trips is stored in the amplifier's nonvolatile memory. ACOM 700S amplifiers are perfect for DXpeditions and field operation. They are extremely compact and employ light-weight construction thanks to the built-in switching-mode power supply. They operate on an extended mains voltage range** (100-120VAC and 200-240VAC) by changing only the main fuses - no internal switching is required. Please read the SPECIAL NOTE at the end of the specifications. ACOM 700S Solid State HF/6-Meter Amplifiers are among the finest and most modern linear amplifiers available anywhere in the world. These outstanding amplifiers are available from DX Engineering!
