Ameco PT-2 Instructions

INSTRUCTIONS
AMECO PREAMPLIFIER
MODEL PT-2
The AMECO PT-2 preamplifier may be added to most existing transceivers in the
frequency range of 1.8 to 54 MHz. Tt improves the gain, noise figure, spurtous
signal and image rejection of the receiver section, This all-new PT-2 preamplifier
has been designed specifically for use with a transceiver, Its sophisticated control
circuitry permits it to be added to virtually any transceiver without modification.
This is accomplished by the use uf automatic antenna switching inside the PT-2,
When the PT-2 senses transmitter RF power, it automatically switches out of the
amplifier mode and connects the antenna directly te the transceiver.
The PT-2 consists of a tuned RF amplifier, covering all the amateur bands from
160 through 6 meters and, in addition, all foreign broadcasts, as well as other
services within this frequency range." Model PT-2 employs a low noise dual gate
FET transistor, providing a noise figure of 1.5 to 3.5 db, over the frequency range
of 1.8 to 64 MHz, The preamplifier will be found especially effective with those
transcetvers employing the Pi-output network of the transmitter section as the re-
ceiver RF stage input. Most transceivers of this type begin to suffer a noticeable
decrease in sensitivity on 18 meters, and especially on 10 meters. 'The PT-2 will
be most beneficial on these bands, 'The inclusion of 6 meters makes it usable with
6-meter transceivers.
'The PT-2 is designed specifically for 117-volt, 60 cycle operation.
The input and output impedances are nominally 50 chms to match most popular types
of amateur installations, The input and output impedances of the PT-2 are not critical
and therefore, no adjustments or modifications are necessary with other impedances.
INSTALLATION
(1) REMOVE THE POWER PLUG OF THF TRANSCEIVER POWER SUPPLY FROM
THE WALL SOCKET AND PLUG IT INTO THE AC OUTLET (MARKED TRANS-
CEIVER) ON THE REAR OF THE PT-2,
FAILURE TO USE THIS OUTLET
AS
DIRECTED CAN CAUSE DAMAGE TO THE PREAMPLIFIER,
An outlet marked
SPARE may be used for a rotator;
however, under no circumstances should a
linear amplifier be plugged into this outlet socket. THE LINEAR AMPLIFIER
SHOULD BE PLUGGED
DIRECTLY INTO THE WALL OUTLET BECAUSE OF
ITS HIGH CURRENT DRAIN,
