If you plan to use a soundcard interface for digital modes, you have a lot more to learn and do, but it CAN be done!

For overall soundcard packet information start at  Ralph Milnes (KC2RLM) website   It is definitely the place to start if you want to try to use a soundcard instead of a TNC with Winlink and Airmail. 

You might want to check out the SignaLink USB device instead of using your internal PC soundcard.  These are sold by Tigertronics, Inc. for about $100 and work as a second soundcard on you computer.  As such, they can be interfaced to work packet, like a normal soundcard, or used to transmit files like the ARRL news over the air.

An item that you might want to check is the deviation of your TNC.  Deviation is the term used to describe modulation of an FM signal. The audio fed into the microphone input causes the transmitter's frequency to shift up and down from the center carrier frequency; the louder the input, the greater the shift.  That instantaneous frequency shift is the transmitter's deviation. Deviation is usually measured as the peak positive or negative shift from the carrier (in other words, it's "center to peak", not "peak to peak").  Click HERE for more information.  This definition is copied from N8UR's website.   (Browse John's site - very interesting reading on a lot of subjects by a talented Ham)
