Mathew, Your 2-way radio projects sounds very interesting. I myself a licensed amateur Radio operator. Several times I've thought about adding a Sound card to my net5501. For VOIP. This might be something to consider... http://www.mini-box.com/Alix-3D-Board-3-LAN-1-MINI-PCI-1_3?sc=8&category=19 or the one I have... http://www.mini-box.com/Alix-1C-Board-1-LAN-1-MINI-PCI_2?sc=8&category=19 But it seems you already have your parts list.
Interesting project though. Please let me know how it turns out for your application. I would love to see your post or updates of any kind.
