Shortwave Jamming?
 

In regard to the last post about the voice of america getting jammed,
i was wondering if anyone could explain too me how jamming is achived
by countries and why they do it -

I am very new to the hobby of shortwave radio, i have just bought a
cheap portable radio and I am fascinated by how much I can recieve! -
I have in the past listened to shortwave on my IC-R5 (radio scanner) -
but because its not a dedicated reciver i had lots of trouble picking
anything up despite having an outside antenna -

Thanx

Jamming is achieved by placing another transmitter on the frequency and
either playing noise, such was with the case of the Radio Marti
transmission, or by simply playing another program.

Why? because the country doing the jamming does not want their people to
hear the program that is being jammed.

The reason for jamming an international shortwave broadcast would be
socio/political. IE: A dictator that doesn't want the people/country he
controls to be exposed to any ideas or information that he doesn't see fit
for them to have access to.

The method would be to transmit a radio signal on the same frequency of the
broadcast that is strong enough to disrupt the original signal. Jamming can
sound like music, talk, constant electronic noise... etc...
