Arduino RTTY

This page contains my source code for my Arduino RTTY transmitter. This device uses an Arduino to control a DDS-60 (Analog Devices AD9851) DDS IC, which in turn creates the required frequencies to transmit RTTY at 45.45 baud (approx) with 170 Hz shift.

The code is a selection of modules glued together, but works well. See the YouTube video below for a demonstration.
