I have been looking all over the place for some Arduino code I can use for a new neat project.
My idea is an Arduino that will control frequency and send fsk (RTTY) to an AD9850 using a USB or PS2 keyboard. The output
would go to a small qrp amplifier and LPF. I want to use this method with my Icom IC-R71A receiver that is sitting and gathering dust. I dont know Arduino software coding.
I have seen lots of beacons, but they are quite limited.
Has anyone done this yet or know the existance of some code that may work?

Any code you find will be hardware specific and would need to be adapted.  If you are not an Arduino programmer, this may be too big of a project for you.

For instance, here is the code for a different DDS that generates RTTY: http://www.george-smart.co.uk/wiki/Arduino_RTTY  You would need a means to check spectral purity of the RF output and may need to add filtering.

Adapting a PS2 keyboard to an Arduino can be done is several ways (software or hardware).  Displays can be parallel or serial, text or graphic.

Too many variables.
