Vectronics VEC-1016K - Manual (Page 13)

1/4" screw thread
7-turns #22 enameled wire
1/2" leads stripped
and tinned with solder
[ ] Remove the coil by unscrewing it from the 1/4" screw threads. Compress the turns of
the finished coil to make it as short as possible.
Each lead must be tinned prior to installation. The wire provided with your kit is coated
with enamel insulation formulated to melt at high temperatures. This quality should
allow you to strip, clean, and "tin" each coil lead in a single operation. To prepare each
lead, hold a hot soldering iron tip against it for several seconds while applying a small
amount of solder. Eventually, the enamel insulation should begin breaking down,
allowing solder to coat and adhere to the wire (it may be easier to perform this operation
with the coil threaded onto the screw). If your soldering iron doesn't generate enough
heat to start the enamel stripping process, scrape the enamel away with an Exacto

knife
before tinning. Make sure both leads are clean and brightly tinned all the way around
before installing.
[ ] Dress, tin, and install a 7-turn coil at L1 and solder. Check coil shape and spacing
before moving on.
[ ] Repeat this operation, installing and soldering a second 7-turn coil at L2.
This completes coil installation. As noted above, no coil is required at L3 for the 49-
MHz version of your kit.
[ ] Install the 9-volt battery snap clip. The red lead is installed at (+ 9V), and the black
at GND. Solder in place.
[ ] Stress relief is provided to prevent battery leads from flexing and eventually breaking
at their connection point. Find a hole part-way back on the left edge of the PC board (not
to be confused with the board's mounting holes at the front and back). Use the plastic tie-
wrap provided in your kit to secure the battery leads in place, as shown below. Insert the
tie-wrap through the hole, close it over the wires, and pull tight. Nip off the excess end.
