assembly is completed. Be sure all excess leads are trimmed away and
touch up any solder joints that don't appear perfect. You may wish to
brush the solder side of the PC board with a stiff brush to make sure
that no loose lead trimmings or solder drippings are lodged between
connections.
Final Assembly:
Locate the whip antenna and matching mounting screw. Insert the mounting
screw through the PC board from the solder side to the component side and
thread the whip antenna on to the screw. For a sturdy assembly, the screw may
be soldered to the PC board. If you desire to do this, use a small nail file or bit of
sandpaper to gently remove the plating from the screw head before soldering
since the plating on the screw head does not accept solder readily.
TESTING, ALIGNMENT AND OPERATION:
To properly test your TV transmitter, you will need these basic tools and
equipment:
Alignment Procedure:
1. Tune a nearby TV set to an unused channel between channels 3 and 6.
Remember since we are transmitting locally, your TV set should have a
nearby antenna connected such as a pair of rabbit ears or a short
dipole style antenna. You cannot operate the TV with the outdoor
antenna or the local cable TV system hooked up to it - after all, their
master antenna may be located 30 miles away!
2. Adjust both R3, the video gain pot and R7, the bias pot to mid rotation.
3. Connect a properly regulated and stable 12 to 15 volt DC power source to the
external power jack. Be sure that your power source can provide at
least 100 ma of current. Depress the TV6 on-off button to turn it on.
4. Adjust channel adjust coil L4 with the plastic tuning tool until you see the
TV screen go blank. Slightly move the slug around this point for the
most blank picture. The sound may or may not be producing noise or
silence since we have not yet adjusted our sound section.
5. Connect a VCR or other video and audio source to the corresponding inputs
on the TV transmitter. Insert a tape into your VCR and press 'Play'.
1. A TV set,
2. A source of video such as a VCR,
3. A 12 to 15 volt DC power source,
4. Plastic alignment tool for L1, L4, R3 and R7.
