16 USING THE LINE OUT SOCKETS
The line out sockets (RCA sockets), labeled L, R,
provide industry standard left and right stereo
line level outputs that can be used to feed audio
to a tape recorder, stereo system, or any device with audio line level inputs. The output is stereo
when the radio is tuned to an FM station broadcast-
ing in stereo.
17 USING THE EARPHONE JACK
The earphone jack can be used with stereo headphones using a 1/8 inch (3.5 millimeter) plug. Sound is
in stereo.
SHORTWAVE ANTENNAS
This radio can be used with basic, long wire
antennas and other high impedance shortwave
antennas (optimally 500 ohm). The length
of a long-wire antenna should be anywhere
from about 30-100 feet (10-30 meters). Best
performance is from copper wire. The antenna
should be above ground, preferably running in
a straight line. Non-conductive insulators should
be used on both ends of the wire to prevent
signal loss. The wire is plugged into the red col-
ored spring socket, AM, SW ANT., on the back
of the radio. Connecting a ground wire to the
black spring socket, GND, often helps reception,
but is not mandatory. The ground wire should
be connected to a cold water pipe or a ground
rod. If no water pipe or ground rod is available,
connect a wire about the same length as the
antenna wire and lay it on the ground. NEVER CONNECT THE GROUND WIRE TO A GAS PIPE.
AM ANTENNAS
Any high impedance (optimally 500 ohm) AM an-
tenna can be used, including long-wires and tuned
loops. A ground wire, as discussed under SHORT-
WAVE ANTENNAS, is even more helpful during AM
reception and often improves reception consider-
ably, even when no supplementary AM antenna is
used.
FM ANTENNAS
Connect FM antennas to the FM ANT. CABLE FM
socket on the back of the radio. These antennas
should have an impedance of 75 ohms. Most anten-
nas fed with coaxial cable are 75 ohm antennas.
If your coaxial cable has a ‘F’ plug, like that used
on North American TV’s and VCR’s, use a F to PAL
converter plug to fit the European style PAL socket
on the radio. (Radio Shack part number 278-265
