Hi Guys,
Let me introduce myself, as I am a new member to the group.
My name is Greg, and my call is ZL3IX. I am interested in HF radio, with
the 160m band as a speciality. My station is completely home brew and the
receiver has a back end that uses a Motorola 56002 DSP eval board.
The front end part of my radio is now very old, and I am in the process of
building a new one, using DDS local oscillators. I am considering using a
PC sound card as the
back end for this version, but have never written programs for a sound card
before.
Could someone please tell me if there is any educational literature on the
use of sound cards - how to write code for them, how to avoid timing
interruptions by the O/S, whether the processing is done on the card or in
the PC itself, etc.
Your help would be appreciated.
73, Greg, ZL3IX
