_«()BILE STATION BI-L1NEAR AMPLIFIER
'-
This Bi-LinearAmplifier
advanced design. It utilizes an integrated circuit, two tubes, four
transistors and four diodes and a grounded grid, tuned plate
circuit for amplication for AM, FM, CW, and- SSB si~nals
The Bi-Linear Ampl ifier will operate over the frequency range
25-54 MHz. However, it is F.C.C. Type Accepted under Parts 89,
91, and 93 over the frequency range 25-40 MHz.
Operation of this equipment requires a FCC license. Failure to
comply is punishable by penalties set forth
Regulations of the FCC. A copy of these Rules is available from
the U.S. Government
possessionof the operator.
The 483 Bi-LinearAmplifier
shipped from the factory, and must be used with a transceiver
which is FCC Type Accepted under Parts 89, 91, and 93 for the
system to be valid.

A special feature of the Amplifier
change over relay which
connections making it perfect for operation with
transceivers not having external amplifier control circuits.
Another feature is that this unit amplifies the received signal,uti-
lizing an integrated circuit
Variable plate tune and load capacitors offer impedance matching
for maximum output to varying antenna loads in the 40-70 ohm
range.
The Bi-Li near Amplifier
suppress radiation that may cause television interference. TVI
problem has been given full consideration in design and layout of
the chassis.
There are, however, some types of TVI that cannot be prevented
within the amplifier. This is particularly true in weak signal areas.
In such cases, a good commercial low passfilter is recommended.
