https://github.com/kg4sgp/arduino-rtty
arduino-RTTY. To use this: Open arduino; Open sketch, and navigate to rtty/rtty.ino; Upload to Arduino. A interrupt driven, PWM audio output , RTTY modulator for the arduino. All you need is a speaker. This program produces 45 baud baudot RTTY, 170Hz spacing, the "standard" shift (mark is high tone) and two stop bits by default but is configurable!

RTTY with Arduino and NTX2 - reactive music
https://reactivemusic.net/?p=12161
RTTY settings. We used rtl-sdr with Max as the receiver, in SSB mode, sending audio via Soundcloud to dl-fldigi to decode the RTTY. The params that worked: 50 baud; carrier shift 400-480 hz (varies) 7 bits per char; no parity; 2 stop bits; reverse mode on; audio input monitor in dl-fldigi
Arduino RTTY QRP Beacon
http://www.radiohamtech.com/page19.html
The Arduino Uno program is set for a bit rate of 50bits/sec or 50Baud. However the RTTY message is “ RY ”, such that any Radio Ham operator wishing to replace this with their own message, please refer to the program code notes for the baud dot encoding within an 8bit / …

RTTY uses a 5 bit code transmitted at 45 or 50 baud. It is a bit like asynchronous or serial data. There are one and a half stop bits and the half is very important. It uses a shift code to get all the letters and numbers out of the 32 code values 5 bits give you. It is transmitted as two audio tones one for mark and the other for space.

rtty-arduino-beacon-audio. Implementacion de una baliza RTTY en Arduino usando el modulo Si5351 que opera desde 8Khz a 144MHz. Permite poner un texto que va a ser modulado en RTTY (default 45.5 Baudios) por la salida 0 del modulo Si5351. Se deberia utilizar un filtro dependiendo la frecuencia en la que utilizarse.
