9W2WOC: Part 1 : Homebrew sound card interface (Digital Mode)

This what we called a "Ham Radio"...

A radio communications service for the purpose of self-training, intercommunication, and technical investigations carried out by amateurs, that is, duly authorized persons interested in radio technique solely with a personal aim and without pecuniary interest.

Ham radio is an international fraternity that transcends the barriers of nationality, race, age, sex, and class. Whenever you take to the air as a ham, you never know who you might find to talk to. It might be an old friend you've known for years; it might be a new friend you haven't met before. Why not join the millions around the world who already have their ham license? They would all like to say hello to you!

Since I've been catching up with all the digital mode for Amateur radio, here some of my free time homebrewing a sound card interface for a digital mode. Its only a PART 1...stay tune for the coming series...
