If you plan on doing radio programming, your best bet is to stick with Windows. Wine will run many programs, but getting the software to talk to the radio through the USB port is usually not possible. I would suggest a copy of Windows XP or Windows 7 32 bit and a dual boot setup. Use a good anti-virus/anti-malware program with XP and you should be ok if all you use online is Radio Reference. It is not difficult to set up a dual boot system, and you will still have Ubuntu for normal use.
