Andy, amateur radio operator KB1OIQ, has released the Version 14 of his Ham Radio Linux LiveDVD containing programs focused on amateur radio and SDR operations.
This is a remastered version of Ubuntu Linux. As of version 13, there are 32-bit and 64-bit versions available, as well as an image for the PengPod 1000.
This version contains a lot of amateur radio software including Fldigi, NBEMS, Gpredict, earthtrack, xcwcp and qrq, XLog and cqrlog, flrig and grig, xnec2c, fl_moxgen, aa-analyzer, owx, VOACAP, glfer, Xastir, gqrx, gEDA, and more!
Version 14 adds GNU Radio Companion, quisk, direwolf, linamc, FreeDV, wsjt-x, and Micro-Fox 15 Config (GPL), and many updates.
Recommended system requirements are a 1GHz CPU and 512MB memory at an absolute bare minimum (gqrx will require more – about twice as much).
Links to the ISO downloads can be found on Andy’s Sourceforge page.
