|
||
|
||
///MATERIALS REQUIRED:///
|
||
|
||
1 - Radio Shack mini-box ( #270-235)
|
||
1 - 1/4 watt resistor, 2.2k-2.4k ohm
|
||
(RS #271-1325)
|
||
1 - 75pf-100pf variable capacitor
|
||
(Hard to find)
|
||
2 - F61a chassis-type coaxial
|
||
connectors (RS #278-212)
|
||
12" - No. 12 solid copper wire
|
||
12" - RG59 coaxial cable
|
||
|
||
|
||
///INSTRUCTIONS///
|
||
|
||
|
||
1. Bare a length of No. 12 gauge solid copper wire and twist around a 3/8"
|
||
nail or rod to form a coil of 9 turns. Elongate coil to a length of 1 1/2"
|
||
inches and form right angle bends on each end.
|
||
|
||
2. Solder the varible capacitor to the coil. It doesn't matter where you
|
||
solder it, it still does the same job. The best place for it is in the center
|
||
with the adjustment screw facing upward
|
||
|
||
Note: When it comes time to place coil in box, the coil must be insulated
|
||
from grounding. This can be done by crazy- glueing a piece of rubber to the
|
||
bottom of the box, and securing the coil to it.
|
||
|
||
3. Tap coil at points 2 1/2 turns from ends of coil and solder to coaxial
|
||
chassis connectors, bringing tap leads through holes in chassis box. Use as
|
||
little wire as possible.
|
||
|
||
4. Solder resistor to center of coil and ground other end of resistor to
|
||
chassis box, using solder lug and small screw.
|
||
|
||
5. Drill a 1/2" diameter hold in mini- box cover to permit adjustment of the
|
||
variable capacitor from the outside. Inspect the device for defects in
|
||
workmanship and place cover on mini- box. Tighten securely.
|
||
|
||
6. Place device in line with existing cable on either side of the coverter
|
||
box and connect to television set with the short piece of RG59 coaxial cable.
|
||
Set television set to HBO channel.
|
||
|
||
7. Using a plastic screwdriver (non-metallic), adjust the varible capacitor
|
||
until picture tunes in. Sit back, relax, and enjoy!!!
|
||
|
||
|
||
Have fun...
