    Easy maintenance. Signatures of the amplifier internal status are stored in a nonvolatile memory for 7 most recent auto protection trips. This information can be forwarded to your dealer for diagnostics. Using an EXCEL APPLICATION (available from ACOM or your dealer free of charge) and a PC you can decode the signatures by yourself, too.

    • Less QRM and improved Electro-Magnetic Compatibility during tuning. Antenna matching can be achieved in less than 10 seconds at a quarter of nominal output power. • Operates without special signals from the transceiver - "ground on TX" and 60W RF drive power are sufficient.

    Tube s/n Voltage Selector Table 2-1. The ACOM 1006 Individual Data If your mains has a different nominal voltage, it will be necessary for you to contact your dealer. Means is provided in the amplifier to reconnect it for 100, 110, 120, 200, 210, 220, 230, and 240 VAC nominal voltage.

  • Page 7: Connections

    No magnetic-field sensitive devices should be located next to the right side of the amplifier as its power transformer is located there. It's best to position it to the right of your transceiver. No temperature sensitive devices should be located above the exhaust hot air area, so don't place it under a shelf. You may prefer to utilize the bottom scales of both variable capacitor knobs (TUNE and LOAD) if you install it on a shelf.
  • Page 8 Transceiver producers give different names to this output and they are for instance TX-GND, SEND, T/R- LINE, etc. Some transceivers require that "ground on transmit" is implemented via a software command, or by changing the setting of a switch on the rear panel, or interior of the transceiver. Check your transceiver's manual.

    It is preferable that you use the wall outlet closest to the source. The installation wires should be at least 1.5sq.mm (AWG 15 or SWG 17) for 200-240 VAC and 2.5sq.mm (AWG 13 or SWG 15) for 100-120V AC. Check if the respective fuses can handle current up to 10A for 200-240 VAC and 20A for 100-120VAC. Check also whether the voltage corresponds to the voltage for which the amplifier is set (S.2-2).

    N O T E If the characters on the LCD are dim or not readable, please follow the method of LCD contrast and back- lighting adjustment described in S.5-1. In this position (called "OFF LINE" hereafter) only the micro-controller is operational, while the amplifier itself is still turned off (the tube is not powered at all).

  • Page 11: Turning On And Off

    There are 14 "ON LINE" information screens, which can be consecutively selected by pressing the NEXT or PREV buttons (see fig.3-2). Their purpose and method of use are described in the next five sections 4-1 through 4-5. 4-1. Turning ON and OFF In order to turn on the amplifier, while the Main Power Switch (located on the rear panel) is on, press the red ON/OFF button (on the right-bottom corner of the front panel) and hold it on for about 1 second.
  • Page 12 Please note, that the REFLECTED POWER readings and the measured VSWR depend on the load impedance only, and not on the amplifier tuning. If the load impedance is different from 50-Ohm pure resistive (nominal), the REFLECTED POWER reading will always indicate reflected power presence (even at excellent tuning).

    c) Tuning Procedure. While a continuous (CW) signal at the desired frequency is still applied: - Look at the upper scale (forward power); obtain maximum power using the upper (TUNE) knob; - Look at the lower (Load Cap) scale and turn the lower (LOAD) knob in order to center the “V”-marker at the "!"...

    Temperature (Celsius and Fahrenheit scales). You can use them to monitor the technical state of the amplifier and the associated parameters in digital form. Selection is made by the PREV and NEXT buttons. You may change them in a closed loop, while the amplifier is used and controlled in operate and standby modes, changes transmit and receive, without any influence by the measuring process.

    In order to enable or disable the Auto-Operate at all, after a contrast and back-light selection (see the previous S.5-1), continue with pressing shortly the PREV+NEXT buttons. The "Auto Operate = ..." screen will appear on the bottom line. Use the PREV button to select OFF or use the NEXT button to select ON. Press shortly the PREV+NEXT buttons again to accept and return.

    7. SPECIFICATIONS 7-1. Parameters a) Frequency Coverage: The six meters amateur band 50-54MHz, extensions and/or changes on request. b) Power Output: 1000W PEP or continuous carrier, no mode limit. In continuous carrier modes (RTTY etc.) for transmissions longer than 15 minutes (up to several hours depending on ambient temperature), the external auxiliary fan must be mounted.
