INTRODUCTION
Enjoy world-wide shortwave radio listening. The Vectronics VEC-101K turns
your AM or AM/FM radio into a world-band shortwave receiver at the push of a
button. Hear late-breaking news from the BBC, a concert from Vienna or a
soccer game from Brazil. Learn the culture of other nations, or brush up on your
foreign language skills. Many interesting and informative programs from all over
the world are available for your enjoyment. You can choose any two 1-MHz
bands between 3 and 22 MHz and select either at the push of a button. Coverage
includes the popular 13, 16, 19, 25, 31, 41, 49 and 60-meter international
shortwave bands, plus much, much more. Select a night-time band and daytime
band so you’ll always have shortwave stations to listen too! Enjoy good
sensitivity and selectivity when used with a car radio; tuning is done on the
radio’s AM dial. This kit features a professional quality glass epoxy PC board
with solder mask and screen printed component legends making assembly a
breeze! Circuit features the NE602 active doubly-balanced mixer IC, and
operates from a long-life and economical 9-volt transistor battery. The VEC-
101K automatically bypasses when not in use, normal AM or AM/FM is not
affected.
TOOLS AND SUPPLIES
Construction Area: Kit construction requires a clean, smooth, and well-lighted
area where you can easily organize and handle small parts without losing them.
An inexpensive sheet of white poster board makes an excellent construction
surface and provides protection for the underlying table or desk. Well-diffused
overhead lighting is a plus, and a supplemental high-intensity desk lamp is
especially helpful for close-up work. Safety is always important! Be sure to use
a suitable high-temperature stand for your soldering iron, and keep the work area
free of combustible clutter.
Universal Kit-building Tools: Although your particular kit may require
additional items for completion, virtually all construction projects require a work
area outfitted with the following tools and supplies:
!
30 to 60 Watt Soldering Iron
!
High-temperature Iron Holder with Cleaning Sponge
!
Rosin-core Solder (thin wire size preferred, .031”)
!
Needle Nose Pliers or Surgical Hemostats
!
Diagonal Cutters or “Nippy Cutters”
!
Solder Sucker (squeeze bulb or vacuum pump type), or Desoldering Braid
