=head1 NAME

PDL::Radio - Amateur radio system built on PDL

=head1 SYNOPSIS

    use PDL::Radio::All;

    ## Basic sounds for testing:

    ## Play 500 Hz sine wave for 5 seconds:

    PDL::Radio::Sine->new(freq => 500)->play(5);

    ## Play 1 second of a sine wave, phase shift 180 degrees, play another second:

    PDL::Radio::Sine->new->play(1)->play(1,PI);

    ## Plot .01 second of a sawtooth wave:

    plot(PDL::Radio::Sawtooth->new->get(.01));

    ## CW (morse code):

    ## Call CQ:

    PDL::Radio::CW->new->play("CQ CQ CQ DE VE3HOY VE3HOY " x 10);

    ## Change keying envelope (hard/min/hanning):

    PDL::Radio::CW->new(shape => 'hard')->play("CQ CQ CQ");

    ## Risetime in milliseconds:

    PDL::Radio::CW->new(shape => 'hanning', risetime => 10)->play("CQ CQ CQ");

    ## RTTY:

    ## Call CQ:

    PDL::Radio::RTTY->new->play("CQ CQ CQ DE VE3HOY VE3HOY " x 10);

    ## Custom baud/freq_shift:

    PDL::Radio::RTTY->new(freq_shift => 90, baud => 20)->play("CQ CQ CQ");

    ## PSK-31:

    ## Call CQ:

    PDL::Radio::PSK->new->play("cq cq cq de VE3HOY VE3HOY " x 10);

    ## Transmit all 0s (two tones):

    PDL::Radio::PSK->new->play("\x00"x100, 800);

    ## Transmit all 1s (single tone):

    PDL::Radio::PSK->new->play("\xFF"x100, 800);

    

=head1 DESCRIPTION

This is a work-in-progress library for generating modem data and playing it through L. Pulse Audio makes redirecting the audio output to programs like L really easy.

=head1 SEE ALSO

L

L is similar to this module except that it interfaces to sndlib where this module interfaces to pulseaudio. L is a pain to setup and I couldn't figure out how to send data to fldigi. Also, L doesn't seem to be on CPAN anymore?
