Universal Kit-building Tools: Although your particular kit may require
additional items to complete, 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 Moist Cleaning Sponge
! Rosin-core Solder (thin wire-size preferred)
! Needle Nose Pliers or Surgical Hemostats
! Diagonal Cutters or "Nippy Cutters"
! Solder Sucker, Vacuum Pump, or Desoldering Braid
! Bright Desk Lamp
! Magnifying Glass
Special tool for this kit:
! 6-32 screw, at least 3/4" long, for winding coils.
! Insulated hex-head tuning wand.
! Small flat-blade screwdriver or tuning wand.
! Voltmeter, digital or analog.
! Two-meter antenna to receive off-air signals.
BEFORE YOU START BUILDING
Experience shows there are four common mistakes builders make. Avoid these,
and your kit will probably work on the first try! Here's what they are:
1. Installing the Wrong Part: It always pays to double-check each step. A 1K
and a 10K resistor may look almost the same, but they may act very
differently in an electronic circuit! Same for capacitors--a device marked
102 (or .001 uF) may have very different operating characteristics from one
marked 103 (or .01uF).
2. Installing Parts Backwards: Always check the polarity of electrolytic
capacitors to make sure the positive (+) lead goes in the (+) hole on the
circuit board. Transistors have a flat side or emitter tab to help you identify
the correct mounting position. ICs have a notch or dot at one end indicating
the correct direction of insertion. Diodes have a banded end indicating
correct polarity. Always double-check--especially before applying power to
the circuit!
