1. GENERAL INFORMATION
1-1. Introduction and Description
This manual explains the installаtion, operation, and maintenance of the ACOM1006 six meters linear
amplifier.
The ACOM1006 is a complete and self-contained linear amplifier that covers the amateur band 50-54MHz
and provides over 1000W output power with less than 60W exciter drive. Antenna VSWR up to 3:1 is
acceptable at full power. Tuning is substantially simplified by a plate-load True Resistance Indicator (TRI) and
by an automatically-controlled input attenuator. Operating parameters are displayed by a multi-functional
back-lighted Liquid Crystal Display. Full break- in (QSK) is standard for transmit/receive switching.
1-2. Owner Assistance
If assistance is needed, you should contact your local dealer first. If you still have an issue you need to
discuss with one of ACOM’s specialists, the contact information is as follows:
• e-mail: <[e-mail]>;
• tel: + 359 2 920 96 55, + 359 2 920 97 80, + 359 2 920 97 81;
• fax: + 359 2 920 96 56;
• mail: ACOM OOD, 151, Nikola Mushanov, blvd., 1330 Sofia, Bulgaria.
1-3. Equipment Supplied
The ACOM1006 amplifier and this manual are shipped in a cardboard carton.
1-4. Features
• Based on the well known ACOM1000 amplifier but optimized for six meters operation.
• Easy to operate. The TRI is a powerful tuning aid which, together with the automatically controlled input
attenuator, helps the operator more quickly and precisely match antennas (5-10 seconds typically). The
auto-operate function (when you have activated it) maintains the amplifier in operate mode for you, thus
saving manual operations and time.
• No heavy outboard antenna tuners required for antenna VSWR up to 3:1. Your amplifier will perform the
functions of an antenna tuner, thus enabling you to change antennas faster and use them over a wider
frequency range (saving tuning time).
• An amplifier that is both user-friendly, and that looks after itself. It is designed to safely withstand up to
300W reflected power, up to 100 milliseconds duration of drive spikes, drive RF "tails" after a PTT or KEY
release, operator's inadvertent tuning errors etc. It would also not cease to function with a "soft" AC
power line and would deliver more than half power at only 75% of nominal mains voltage. It would
withstand up to 10 milliseconds (down to zero) voltage drops, and up to +15% line voltage spikes, which
is important particularly when used at field days, DX-peditions, and other portable events.
• LCD comment display. All amplifier status indications are explained via detailed text displayed on the dot-
matrix back-lighted liquid crystal display (LCD). The upper line strip on the LCD always reads directly
peak forward power. LED indicators are provided for conditions of operate, attenuation-on, and ON/OFF.
• 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 noise in the room: the input bypassing and the vacuum antenna relays are virtually silent even in
QSK CW mode due to their special mounting.
