I am rebuilding a PC dedicated to my ham shack. I will likely load it with WinXP and Unbutu dual boot. It is a decent laptop with a second monitor. My sig line should show my current system, though I am working to expand QRP, DX, and satellite. Can you share your top three or four favorite software tools? Satellite trackers, propagation info, Log Books, screensavers, Antenna tools etc Thanks for the feedback!
