[Elecraft] K3 RTTY MODE

[David Fleming]

For those interested in playing with microcontrollers, there is a very easy way to use an Atmel AVR to convert the AFSK from your favorite RTTY software to true FSK - and provide PTT as well.

A few weeks ago, Kok Chen, W7AY, and I had a discussion about Atmel AVR microcontrollers. I told him I had always wanted to learn how to do it but couldn't come up with a good idea for a project to get me started. He directed me to this project developed by Doug Hall, K4DSP.

This sparked my interest, and I decided to build one. Just finished it this weekend. It works like a charm with cocoaModem and the K3 - and I got my feet wet with microcontroller programming.
