Hi All,

I want to transmit AM RF signal (1khz to 20 Khz) using sound card.
The audio out of sound card will be connected to Antenna directly.
i need software that take sound file and generate AM RF signal
for the above range and produce desired AM signal to be transmited on
air,
high out put power is not required,
I am unable to find any software, Any help by anyone will be highly
appreciated. thanks in advace.

"AM" stands for "amplitude modulation". Your sound card can produce the modulating signal, but not the carrier. The carrier is the signal that is modulated. You wrote nonsense that shows a lack of understanding what modulation is. Read a little more.
