Did some rearranging and added a dedicated radio desktop machine running Windows 7. It's an old HP DC5100 commercial grade machine. Perfect for radio since it has a built in speaker and allows audio pass-through so I can monitor the audio from the radios. Linux is great for a lot of things but it's a major PITA for amateur radio. Lucked out and found a nice cart for it at a thrift store today for $9. It's perfect actually. Going to get it set up for ADS-B tracking and other RTL-SDR applications tomorrow. Already have Multi-PSK, FL-Digi, Sorcerer, UISS, MMSSTV, DIGTRX, UI-View-32, WXTrack, WXToImg, and Audacity all set up.
