PAY TV DECODER PLANS:
--------------------
  Due to different scrambling systems, you might find it neccesary to change
the range and values of the variable capacitator.
 
MATERIALS REQUIRED:
------------------
1    Radio Shack mini project box (#270-235)
1    1/4 watt resistor, 2.2k 2.4k ohm (RS #271-1325)
1    75pf - 100pf variable capacitor (Very hard to find!)
2    F61a chassis type coaxial connectors (RS #278-212)
12"  No. 12 solid copper wire
12"  RS59 coaxial cable
 
INSTRUCTIONS:
------------
1>  Dare 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" and form right angle bends on each end.
 
2>  Solder the variable capacitor to the coil.  It doesn't matter where, it DIAGRAM:
still does the same job.  The best place for it is in the center with the
adjustment screw facing upard.
 
Note:  When it comes time to place coil in box, the coil must be insulated from
grounding.  This can be done by glueing a piece of rubber to the bottom of the
box, and securing the coil to it.
 
3>  Solder 2 pieces of copper wire at points 2 1/2 turns from ends of coil and
solder to coaxial chassis connectors, bringing leads through holes in chassis box.  Use as little wire as possible.
 
4>  Solder resistor to center of coil and ground other end to chassis box,
using solder lug and small screw.
 
5>
   Drill a 1/2" diameter hold in minibox cover to permit adjustment of the
variable capacitor from the outside.  Inspect for mistakes and place cover
on and tighten securely.
 
6>  Place device in line with existing cable on either side of the converter
box and connect tv set with the short piece of RS59 coaxial cable.  Set tv set
to HBE channel.
 
7>  Using a PLASTIC screwdriver, adjust the variable capacitor until picture
tunes in.  ENJOY!!!!!
