INTRODUCTION TO THE TV6C:
The answer to all your TV and VCR hook-up problems is now in your hands.
Your TV6C TV Transmitter kit is the handy "wireless wire" you can use to
connect up the whole house for TV of your choice!
The TV6C accepts normal video and audio signals from VCRs, camcorders, or
TV cameras and generates a low power TV signal that can be picked up by
nearby TV sets. Please be aware that this kit is a real transmitter and can be
received by others - whether they want to or not! Be especially cautious to not
cause any interference to neighbors or others close by, they are entitled to
enjoy their own choice of programming without any interference from you. Pay
particular attention to the FCC Rules section later in the manual.
In keeping with our spirit of getting folks to build and learn, you'll see that your
kit has step-by-step instructions that carefully guide you to a finished, fully
operating kit. And, you'll not only build the kit, but learn it too! Kit building is a
fun and rewarding way to spend an evening at home, especially on a cold
winter night.
BUILDING YOUR KIT:
Many Ramsey kits can be classified as single evening kits suitable for
beginners or old pros and this one is no exception. But, don't let confidence
get in the way of better judgment. With well over 100 solder joints, even being
right 99% of the time will still allow one error to creep in! Therefore, please
take to heart these following guidelines:
• Use a comfortable soldering iron or pencil for assembly. 30 to 50
watts is ideal.
• Keep your iron tip clean; it will then produce professional, shiny
and reliable joints. Use a damp sponge to wipe your tip before
every joint. Use the wife's kitchen sponge and not your expensive
super-dandy-whiz-bang car wash sponge!
• Good lighting is a must; why strain yourself with poor lighting?
• Take advantage of the fact that our manuals are written in stages,
take a break between sections and check your work before
proceeding on.
• Be on the look-out after each solder joint for a splash, bridge or
errant wire lead that could prove hard to find later.
• Enough said, let's get building....
