For Ham radio operators out there, you might consider KB1OIQ Andy's Linux. It is available on Sourceforge at https://sourceforge.net/projects/kb1oiq-andysham/. It is a remastered version of Ubuntu 14.04LTS. The recommended system would have a 1GHZ CPU, 1GB of memory, and 10-15 GB of drive space. It can also be run from a live CD/thumb drive. Both 32 and 64 bit versions are available. This distribution has many software packages included which would be of interest to hams, such as FLDIGI.
