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!

These amplifiers were the first to include fully-automatic tuning and sophisticated digital-control capabilities. ACOM's revolutionary 2000A amplifiers deliver maximum legal power in all modes and operate on all amateur HF bands 160 to 10 meters. Be sure to read the SPECIAL Note, below. These amplifiers follow your transceiver's band and frequency automatically in far less than a second. No special cables are required: Just a "dit" on CW or "AHH" on SSB is enough for instant band and band segment changes. ACOM 2000A amps break every amateur band into multiple frequency segments. The user can store up to ten (10) sets of tuning adjustments for every frequency segment - allowing individual settings for multiple antennas on each band. By completely eliminating time-consuming tune-up procedures, ACOM 2000A linear amplifiers give contesters a real edge. At the core of the ACOM 2000A is a classic HF amplifier design that employs two matched 4CX800A high-performance ceramic-metal tetrodes for maximum efficiency. ACOM uses these rigorously tested tubes with today's most advanced digital control technology to create an amplifier with outstanding performance, features and reliability. Measured third and fifth order IMD are typically 40dB and 45dB down, respectively. Typical harmonic emissions are as low as -55dBc (second) and below -70dBc (for third and above). Thus, probability of QRM, BCI or TVI is dramatically minimized. ACOM's 2000A remote diagnostic features and modular design ease fault isolation and repair. The protection system makes damaging one of these amplifiers difficult. Information on the 12 most recent protection trips is stored in an INFO BOX for remote diagnostics via phone line, PC, and Internet. Full break-in (QSK) is based on a built-in vacuum relay. Transmit/receive switching sequence is secured by a dedicated microprocessor. * Frequency Coverage: All Amateur Bands 1.8-29.7 MHz * Power Output: 1,500W PEP, 1,500W continuous carrier (the external auxiliary fan must be installed for operations of continuous carrier transmissions longer than 15 minutes * Hum and noise: Better than 35dB below rated output * Harmonics Output Suppression: Better than 50dB below rated output * Input and Output Impedance: Nominal values: 50 Ohm unbalanced output; Input circuit: broadband, VSWR less than 1.3:1, 1.8-29.7 MHz Amateur Bands (no tuning, no switching); Relay Bypass Throughput: VSWR less than 1.1:1, 1.8-29.7 MHz Amateur Bands * Automatic Tuning: Load Impedance Matching - less than 3 seconds; Band Change - less than one second; Segment Change - less than 0.2 seconds * RF Gain: 14.5dB, frequency response less than 0.5dB (50 to 60W drive power for rated output) * ALC: grid-current derived, -11V max, rear panel adjustable * Primary Power: 180-264V (200, 220 and 240V nominal taps, 10 percent tolerance), 50-60Hz, single phase, 3,500VA consumption at rated output * SPECIAL Note: Order part number AOM-2000A to wire the AC plug yourself; order part number AOM-2000A-240 for pre-wired 240 volt operation * Complies CE safety and electromagnetic compatibility requirements, as well as FCC regulations * Size: W 17.3 x 19.7 x H 7.1 in.

ACOM 1500 HF + 6 Meter Linear Amplifiers
ACOM 1500 HF + 6 Meter Linear Amplifiers are user-friendly and look after themselves. They are designed to safely withstand up to 300 watts of reflected power and up to 100 milliseconds duration of drive spikes. These amplifiers also continue to function with "soft" AC mains and will deliver more than half power at only 85 percent of nominal mains voltage. They can withstand voltage drops for up to 10 milliseconds and can tolerate 15 percent mains voltage spikes. This level of tolerance is especially important on Field Day, during DXpeditions, and at portable operating events where emergency power is relied upon. Please see the SPECIAL Note, below. The True Resistance Indicator (TRI) is a powerful tuning aid that helps the operator to quickly and precisely match the antenna impedance to the optimum tube load impedance. The auto-operate function (when enabled) maintains the amplifier in the OPERATE mode, thus avoiding unnecessary manual operations. Your ACOM amplifier will enable you to change antennas virtually instantaneously and allow you to use your antennas over wider frequency ranges. Broadband input matching presents a very good load to the transceiver over the entire spectrum of 1.8-54 MHz. These amplifiers produce 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. ACOM 1500 amplifiers utilize a single 4CX1000A ceramic and metal radial-beam tetrode vacuum tube with plate dissipation of 1,000 watts. Tube protection includes permanent monitoring and automatic protection of plate and grid voltages and currents, as well as the exhaust air temperature. These pieces of data are essential to indicate 4CX1000A operating conditions.

ACOM A3x2000A HF Power Splitter/Combiner
The ACOM A3x2000A HF Power Splitter/Combiner is a passive device designed to sum the outputs of three HF linear amplifiers into a common load while the amplifiers are driven by a single exciter. This allows for better signal processing, modular amplification setup, and more consistent power levels. For best results we recommend three automatic amplifiers of the type ACOM2000A. Manual tune amplifiers with a precise tuning indicator like ACOM1200, ACOM1000, ACOM1010 or ACOM1011 can be used. Models that use a broadband input network are recommended. An automatic protection circuit is implemented in the ACOM A3x2000A, which monitors the three amplifier outputs during operation. In case of an imbalance, the protection circuit cuts the drive to the amplifiers and switches transceiver output to an internal 50 Ohm dummy load. The imbalance power is swamped by powerful resistors until the protection trips. Circuit reset is accomplished by a simple push-button. Specifications: * Frequency coverage: 1.8 – 30 MHz, continuous * Power output: 5 kW PEP, VSWR < 1.3:1 * Input impedance: 50 ohm unbalanced, UHF, SO-239 connectors, broadband * 8.268 in. wide, 12.795 in. deep, 7.677 in. tall * 14.1 lbs.
