SETTING UP THE SC1 FOR A HOME STEREO SYSTEM:
❒
1. Make sure the stereo AM-FM receiver has provisions for attaching an
external AM antenna. Sometimes, the built-in antenna wires are
detachable from the rear-panel antenna terminals.
❒
2. Prepare a short coaxial cable with suitable connectors or wire ends to
make a neat connection between the SC1 and the receiver AM antenna
terminals.
❒
3. Provide a 9 to 12 volt battery power supply. A 9-volt battery snap
connector is easily wired in parallel with the 12-volt connector on the PC
board.
❒
4. Connect a suitable shortwave receiving antenna to the SC1 antenna
jack. 10 to 20 feet of hookup wire will do fine.
SETTING UP THE SC1 FOR AUTOMOBILE USE:
The 12-volt DC power connection for the SC1 is accomplished most easily
by the use of the Ramsey CLG-1 cigarette lighter cord or a similar cord from
Radio Shack. You may also make a permanent installation using the
appropriate coaxial style DC power plug to the SC1 and "hard" wiring into the
car's fuse block.
Some automobile ignition systems cause noise which needs to be
suppressed for satisfactory operation of ANY radio device. When using this
converter in a car, you may have to install a noise filter on your alternator, or
suitable resistor-type spark plug wires. A competent mobile CB radio shop or
technician can be helpful in such cases. Radio Shack carries a variety of
noise filters and eliminators.
The most common auto radio antenna connector is the Motorola style plug.
The cheapest and neatest antenna hookup for the SC1 is made from a male-
to-female in-line extension cable. Radio Shack No. 12-1312 is a 24" length
with a plug at one end and an insulated jack at the other. Cut the cable in
half and solder RCA-type plugs to the two cut ends, using correct coax cable
preparation and soldering techniques. The new cable with the male Motorola
plug connects between the car radio and the SC1 receiver jack. The other
short cable permits a neat connection of the car radio antenna to the SC1
antenna jack. Before buying or cutting any cables, however, study your car
radio installation and how you will locate the SC1.
