6. You should now see some resemblance of a picture on your TV screen.
Now adjust channel adjust coil L4 for best picture.
7. Adjust the video gain pot R3 for best 'brightness' in the picture and bias pot
R7 for best overall picture. These two adjustments interact and it is
best to 'fiddle' back and forth until best picture is obtained. You may
wish to touch-up the channel coil L4 also.
8. Adjust the audio subcarrier coil L1 for best sounding audio.
Using the TV6 within the home:
One of the most practical uses of the TV6 is to hook it up to your VCR and
transmit a tape to other TV sets throughout the house, yard or to the garage. This
connection involves using shielded audio or video 'patch cords' to connect the
audio and video outputs from the VCR to the TV transmitter inputs. These patch
cords are available at any Radio Shack or stereo shop, and don't believe that
you'll need the Ultra-Classic El-Mucho-Bucko gold plated, oxygen free type
either! Any good quality cable suitable for audio will pass your video just fine.
Remember, even if this is your only use of the TV transmitter, it is your
responsibility to ensure that your operation does not interfere with your neighbors
TV viewing - and don't forget, someone may be watching what you're watching
too!
Antenna considerations:
The TV6's on-board whip antenna is suitable for most in-home applications and
can usually transmit throughout an average sized home. If you need more range,
an external antenna connected to the TV transmitter's antenna jack will do the
trick. Use a length of RG-59 or RG-58 coax cable to locate the antenna in a
position closer to the TV set when reception is desired. Under no circumstances
should you attempt to connect a larger antenna to the TV6. FCC rules are very
strict as to radiated power allowed. In the interest of remaining invisible to others,
use a minimum amount of antenna system for reliable operation. Remember your
obligation is to not cause interference to others. Your neighbor may have
invested in a high gain TV antenna system and top quality TV set and doesn't
need you to come along to spoil it for him. If you desire to connect the TV6
directly to a TV set, be sure that there are no other connections to the TV set's
antenna terminals!
Troubleshooting Hints:
If your TV6 does not work at all, re-check the following:
•
Correct orientation of all transistor flat sides.
