- Features
- Usage ACOM 1003 is a self-contained, full-featured linear amplifier covering all amateur bands from 1.8 MHz to 54 MHz. It delivers 1000 W power output PEP or 900 W continuous carrier, with less than 80 W input power. Easy to operate Antenna matching is made simple by the True Resistance Indicator (TRI) which is a bar scale for accurate setting of the plate-load impedance real part. A front-panel button-controlled input attenuator allows for easy drive power reduction during tuning and restoration after that, without the need of transceiver re-adjustments. Peak power bar graph indicator, operational parameters and text messages are displayed during operation on a two-line OLED display. Switching RX/TX is fast and CW QSK compatible, using a silent HF reed relay. No external antenna tuner needed No need of external antenna tuner (ATU) for antenna SWR up to 3. A SWR up to 3 is allowed at 1000 W forward output to the antenna. User-friendly and durable Operator selectable class AB2 mode for best linearity in SSB mode or class B for reduced plate dissipation in continuous digital modes; Operator selectable modes of full or 50% reduced power output with no efficiency deterioration; Auto controlled cooling air flow; Continuous monitoring of amplifier parameters and tube protection; Able to monitor 18 operator-selectable amplifier parameters on the display; Unique ACOM protection for the bands switch (BAND); Original ACOM TRI prompt: bar scale for quick and accurate setting of the plate-load impedance real part while matching the antenna; Factory tuned input lowpass filters for best linearity and input SWR less than 1.3 in each amateur radio band. OLED comment display Two-line OLED display with peak-reading forward-output power bar graph and 18 operator-selectable amplifier parameters on the display. Three antenna outputs Three antenna outputs are selectable by a push-button on the front panel. Less noise in the shack HF antenna reed relay for a virtually silent, QSK compatible CW operation. Transceiver-independent The amplifier operates without special signals from the transceiver - "Ground on TX" (PTT) and 50-80 W RF drive power are sufficient. Single tube operation Uses a single ceramic/metal power triode 3CX800A7 in cathode driven, grounded grid configuration. Tube protection Continuous monitoring of amplifier parameters and tube protection. Output RF arc protection Original ACOM HF arc protection at the output, or at the antenna. Power supply Single phase mains power, 90-132 / 180-264 VAC at 50-60 Hz, power consumption at rated output – up to 2000 VA @ 240 VAC. Easy maintenance Non-volatile memory with SIGNATURE records of the most recent 8 Serious (Hard Fault) Protection events. Documentation The User's Manual is available as a PDF file only.
