Lately my old Linux box has been forgetting which card is which and hanging up the streams, so I'll be scrapping the multiple sound cards and replacing them with a Delta 1010 sometime in the next couple days. With ten available inputs instead of three I'll be able to add a few more feeds, like networked San Francisco ARINC on 129.4 and HF 6640 & 8933, some VOLMET broadcasts on 6604 and others, as well as some military HF.
I don't know long long I will be down, probably an hour or so, but if significantly longer you'll know I screwed the pooch.
