signal. Decrease the signal generator output level until the signal is barely
audible. Adjust the appropriate antenna trimmer capacitor (C10 or C11,
depending on which band is being aligned) for the loudest signal. As the
trimmer is brought into tune, you may have to continuously lower the generator
output to notice further improvements. Repeat for the second shortwave band.
OPERATING INSTRUCTIONS
Power requirements: The VEC-101K requires a 9-volt transistor battery for
operation. Alkaline batteries are recommended—they cost more initially, but are
more economical to use over the long run.
Enclosure: The VEC-101K should be mounted in an enclosure to protect it from
damage. Vectronics can supply enclosures for most of the Vectronics kit line.
The Vectronics enclosures have all needed buttons and knobs, and have decaled
front panels. If you chose to supply your own enclosure, it should be roomy
enough to house the battery.
Operating the unit: When power switch SW1 is set to “off” (push-button
extended) the 9-volt power is removed from the converter, and the antenna is
automatically connected directly to the receiver. Activating the power switch
places the converter in line between the antenna and receiver. Bandswitch SW2
is used to select the desired shortwave band. Depressing SW2 (button in) selects
the lower frequency shortwave band, releasing SW2 (button out) selects the
higher frequency shortwave band.
The car radio tuning control is used for tuning across the shortwave bands, just
as it would be used to tune across the AM broadcast band. The radio volume
and tone control are set for the best listening level. Turn the converter off when
not in use to conserve battery power.
Understanding Shortwave Broadcasting: Getting the most from your
shortwave converter requires a basic knowledge of radio propagation, and where
SW broadcasts take place.
