Just like I run a Windows VM on my Mac for HRD, I also have a Linux VM. When on Linux, I work with CQRLog which I find works extremely well. It really does all I need. I've got a Linux friend, also a fellow ham, that is consulting me on working with Linux, which is a learning curve. I tried taking an old desktop computer I built back in '03 and using it for a Linux box in the shack about five months ago and the software ran nicely on it, but the processor just crapped out. At Christmas, I took advantage of some of the NewEgg sales and purchased some hardware, about 20% of what I need, for a new computer. It will be an AMD 8 core processor machine, so it will be good for a long while. The big issue I've had with Linux is getting N1MM+ to work on it using a Wine emulator or whatever. I have it working, but without rig control. That's not a big issue, because most contests don't care about recording frequency, just band.
