SC-1

when portable broadcast band radios are very cheap, or often available free
in various promotions, we can only suggest that you study how a particular
radio is designed and that you figure out how to get the RF output of the SC1
beyond the internal ferrite rod antenna of the AM radio. To get the most from
your SC1, we suggest that you plan to use it with a good quality AM radio
with an external antenna connection.
WHAT YOU CAN EXPECT TO HEAR
The SC1 is designed to let you easily tune in shortwave broadcasts from
around the world, using the dial of your existing AM radio for easy tuning.
These broadcasts are AM (Amplitude Modulation). You will also hear a
variety of other "interesting" sounds, but just remember that this receiving set-
up is designed for listening to AM style broadcast formats.
Morse code (CW) or teletype signals will probably sound like hisses or
buzzing noises. If a code signal really sounds "good", it's either because it is
being transmitted in AM-modulated form, or perhaps the signal is so close to
an AM broadcast carrier that the carrier acts as a "beat frequency
oscillator" (BFO). Even though this converter can let you tune through several
different Ham radio bands, the signals are not likely to be intelligible.
Reception of CW and SSB (single-sideband) signals requires the use of a
BFO. This is not a complicated feature, but it is beyond the purpose of the
SC1. (Hams and experimenters: please see the section for you at the end of
this manual.)
