The other reason I might want an external interface is to have a larger dynamic range into the computer. Most computers have a 16 bit A/D. With a 24 bit A/D you will have less trouble with strong signals causing overload when trying to receive weak signals.
IMHO, using the computer audio I/O is a nice way to get your feet wet in digital modes. However it is like a beginning rig -- limited in performance. People who opt for an Elecraft class radio probably will want something better. Cheers - Bill, AE6JV On 8/19/12 at 20:30, her...@comcast.net (Jeff Herr) wrote: >Good explanation!
