High Performance 2-Meter

Preamp Kit

Integrated RF System

Put a high performance

LNZ on your antenna that

will pull weak signals out of

noise, combat “intermod”,

and knock down local RFI -- all at the same time!

More than a preamp, the Vectronics VEC-1402DK is

an integrated RF system that attacks three important

modern-day reception problems head-on. First, it boosts signals at

the antenna using a premium grade 1 dB noise-figure microwave

transistor to overcome feedline loss. Second, it provides razor-

sharp bandpass filtering that prevents your receiver from being

choked up with powerful out-of-band signals. Finally, it provides

an optional built-in balun to eliminate unwanted electrical noises

and local RFI signals picked up on the outer surface of your coaxial

line. In short, the VEC-1402DK allows your scanner or VHF

receiver to perform its absolute best -- even in the toughest RF

environment! Preamp easily fits into small project box or PVC

pipe for antenna mounting. All parts are provided for powering

over the feedline. More immune to overload and static discharges

than inexpensive GaAsFETS. Requires 9-14 Volts DC. Size:

x3x1 inches.

Skill Level: Intermediate Requires more involved construction,

you may use some test gear for final adjustment or tuning.

Receiver Kits

High-Performance, Sensitivity

Even beginners can easily build

these high-performance direct con-

version receivers for the HF bands.

You’ll be pleasantly surprised with

their excellent sensitivity that rivals

receivers costing many times more.

You’ll marvel at the clear reception

of DX signals from all around the

world when you copy CW, SSB and

even AM signals. Built it to cover

the entire band or tailor it to cover

just a portion of it for smooth band spread

tuning. Ideal for on-the-go or at-home QRP

operation with your homebrewed QRP trans-

mitter of VECTRONICS QRP CW

Transmitter Kit. High performance is

achieved with a NE602/612 mixer-oscillator

chip connected differentially to a high gain LM386 audio amplifier.

The oscillator-mixer is voltage regulated by a 78LO5 for best sta-

bility. The antenna input has a high-Q parallel tuned circuit with a

front panel RF gain control to minimize interference and prevent

overloading from strong signals. It has smooth varicap tuning with

a shielded VFO coil for maximum stability. You can configure the

tuning to cover the entire band or to cover just a portion of the band

for more bandspread tuning. Delivers plenty of volume for head-

phone operation and will even drive a small speaker. Uses 9 volt

battery (not included). 1

x5 inches.

Skill Level: Moderate Requires some test gear -- usually a basic

multimeter for some final adjustment or tuning.

VEC-1100KC, $14.95. Matching all metal cabinet for

20/30/40/80 Meter Receiver Kits. Includes knobs, hardware and

rubber feet. Has brushed aluminum looking front panel decal.

144/220/440 MHz Preamp Kits

Low-Noise Amplifier

Soup-up your antenna

system and “pull the weak

ones” with this easy-to-

build LNA (low noise

amplifier). Here’s a high-

gain, low-noise preamp that will work wonders

for your scanner or ham-band receiver. Unlike

low-cost GaAsFET preamps, Vectronics kits use a

high quality microwave type bipolar device for

exceptional low-noise performance and immunity

from damaging electrostatic discharge. A high-Q

LC tuned input filter fights overload from out-of-band signals, and

careful output matching ensures efficient energy transfer into your

50-Ohm feedline. Will cover near-by out-of-band commercial

channels with only minor retuning. Size: 1x1

inches.

Skill Level: Simple Calls for a few basic tools -- a soldering

iron, cutters, pliers, wire-strippers and a small screwdriver. Doesn’t

require test equipment for final adjustment or tuning.

2/6/10 Meter FM Receiver Kits

Ideal for Learning about Ham Radio

Turn on and tune

in the world of ama-

teur radio repeater

action with these

superb educational

kits. If you ever

wanted to get into ham radio, here is the

perfect way to get started. These kits

will put you in front-row center position

to experience what it’s like to “work”

FM repeaters and talk with other amateur

radio operators in your area. Learn the

lingo while you learn about FM communication and study for your

license! Careful step-by-step instructions guide you through the

construction and tune up. Each model covers the entire FM sub-

band and runs off a self-contained 9 volt battery (not included).

Plug in an 8 Ohm speaker or headphones for “loud and clear”

reception. Size: 1

inches.

Skill Level: Intermediate Requires more involved construction,

you may use some test gear for final adjustment or tuning.

VEC-1000KC, $14.95. All metal matching cabinet for 2/6/10

Meter FM Receiver Kits. Includes knobs, hardware and rubber

feet. Has brushed aluminum looking front panel decal.
