LA-1K SPECIFICATIONS
Page 1
PALSTAR
The LA-1K RF Sensing Dual HF LDMOS amplifier is a complete
stand-alone amateur RF LINEAR amplifier.
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 classification, 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 “off” 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
•
Amplifier unit
•
Shipping box (
please keep box for warranty repair, etc.
)
As per FCC 15.21 changes or modifications not expressly approved
by Palstar could void the user's authority to operate the
equipment. No tune up procedure exists.
