[amsat-bb] Eagle -- high-speed digital

On the high speed digital portion of Eagle, are you guys close to making any decisions about which parts will be used for the satellite and ground station? I was just thinking the ground station might also work for terrestrial digital radio, assuming the effort is going to be put in to design all this anyway. I'm just prodding a little bit, maybe trying to get a little bit of the vision of what this hardware is going to look like approximately. Are FPGA's, microprocessors or DSP chips going to be used? What is the big picture?
