WebI’ve coded the logic to transmit some text using RTTY. The carrier shift is 170hz and the baud rate is 45.45 bps. I transmit a start bit, followed by the 5 ITA2 bits corresponding to the letter I’m transmitting, followed by a stop bit, for each character in the string. WebThe RTTY mode is a traditional mode used by radio-amateurs like CW, AMTOR and ASCII.RTTY, ASCII and AMTOR use two frequencies which are filtered, each one corresponding to a binary digit (1 or 0). These two frequencies, separated by a shift, modulate the RF when transmitted and the modulation is called Audio Frequency-Shift …

WebAlthough these standard tones are used by most Amateurs, it's possible to operate RTTY using other frequency tones. This is fine as long as you maintain the standard 170 hz shift (2295-2125 = 170 hz). Some commercial TNC's such as the KAM and PK232 use a 200 hz shift when running AFSK. Although 200 hz shift will work OK, 170 hz is standard on HF. http://f1ult.free.fr/DIGIMODES/MULTIPSK/RTTY_en.htm http://arrl.org/frequency-allocations fishing undies
