Public Methods

Method	Description
RTTY ( double frequency = 3000, int samplerate = 42000, int baud = 300, int shift = 425, double low = 0.1, double high = 1.0, int stopbits = 2 ) : System	Constructor: Setup RTTY and Sound settings.
Start ( ) : void	Start the sine wave playing.
Stop ( ) : void	Stop the sine wave from playing.
transmitSentence ( string sentence ) : bool	Gets a sentence ready to be transmitted next. If this is called again whilst a sentence is already queued, the queued sentence is overwritten with the new one.

Private Methods

Method	Description
BufferNeeded ( object sender, EventArgs e ) : void	Event Handler: Called when a new buffer is needed. Calls updateBuffer() on a new thread.
convertToBits ( string toConvert ) : List	Convert a string to a list of bits (booleans) incl. start bits and stop bits.
updateBuffer ( object o ) : void	Fills the next buffer with a sine wave, amplitude modulated with the data to be transmitted.

Method Details

RTTY() public method

Constructor: Setup RTTY and Sound settings.

public RTTY ( double frequency = 3000, int samplerate = 42000, int baud = 300, int shift = 425, double low = 0.1, double high = 1.0, int stopbits = 2 ) : System
frequency	double	The frequency of the sine wave.
samplerate	int	The sample rate of the sound.
baud	int	The baud rate of the data transmission.
shift	int	The eventual radio frequency shift in Hz. (Not used)
low	double	The amplitude for a 'low' bit. 0.0->1.0
high	double	The amplitude for a 'high' bit. 0.0->1.0
stopbits	int	The number of stop bits for each byte.
return	System

Start() public method
