EXTERNAL DATA CONNECTORS
The LA-1K RF Sensing Dual HF LDMOS amplier is a complete
stand-alone amateur RF LINEAR amplier.
It is completely independent of data from an external source to
determine frequency for tracking from Band to Band. As a result of this
feature, the LA-1K will function with any transmitting device without
interconnecting data cable attachments.
The power output of the LA-1K is 1000 Watts PEP CW ICAS (Intermittent
Commercial and Amateur Service). Under the ICAS classication, the
use of the LA-1K is designed for transmissions that are of an
intermittent nature.
Intermittent operation of the LA-1K implies that no operating or
“ON” period of 1000W of Continuous Carrier Power will exceed
approximately 1(ONE) minute. On Single Side Band (SSB) voice
duty there is no limit on transmit time at full power of 1000W PEP.
Every “on” period must be followed by an “o” or standby period of at
least the same or longer duration. The LA-1K provides a +10dBm@1kW
RF tap feed at the rear panel to provide provisions for “PURE SIGNAL”
operation provided by compatible transceivers. The level adjustment
is calibrated at the factory. The LA-1K was designed to be fully
compatible with the Palstar HF-AUTO automatic antenna tuner.
Included with the LA-1K:
• Two (2) line cords for 110VAC and 220VAC
• User Manual
• Amplier unit
• Shipping box (please keep box for warranty repair, etc.)
As per FCC 15.21 changes or modications not expressly approved
by Palstar could void the user's authority to operate the
equipment. No tune up procedure exists.

THEORY OF OPERATION
PALSTAR
The LA-1K automatically selects bands and it is normally not necessary
to connect band data cables between your transceiver and the LA-1K
amplier.
RADIO INTERFACE CONNECTOR:
This connector is designed to be
pin for pin compatible with other
ampliers. The required cables are
widely available. They can be used
to connect to ICOM and YAESU
transceivers.

RS232 BAND CONTROL CONNECTOR:
This connector is designed to be used with Kenwood transceivers for
band selection using a null modem adapter. It is also designed to
control the amplier from a computer.
