USA religious broadcasting to other continents
You'll easily tune in broadcasts from many other countries as well. As you
become more and more familiar with the world of shortwave broadcasting,
you'll be deciding on your own favorite band.
You will hear a variety of other "interesting" sounds, but just remember that
this receiver is designed for AM only. If a Morse Code signal really sounds
"good," it is because it is being transmitted in AM tone-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 receiver can
let you tune through several different HAM radio bands, the signals are not
likely to be intelligible. Reception of CW and SSB signals on an AM receiver
requires a BFO. This is not a complicated feature, but it is beyond the
purpose of the SR2. Our companion receivers designed for the HAM bands
will let you tune into these SSB and CW broadcasts.
SHORTWAVE LISTENING AS A HOBBY
Many people worldwide enjoy listening to shortwave broadcasts of all kinds,
and they keep written records of what they hear. Almost every nation on
earth has some sort of shortwave broadcast service, though many are
much more challenging to tune than the powerful signals of Radio Moscow
and the BBC. In addition, these "SWLs" (Shortwave Listeners) listen to HAM
operators, government and commercial stations and even clandestine
operations. Some shortwave listeners enjoy collecting QSL cards from
stations which they have logged. Shortwave listening is, for some, a step
toward getting a HAM radio license. For others, it is a great hobby in itself.
The SR2 Shortwave Receiver is a good introductory receiver for this hobby.
