Some time ago I bought a cheap DVB-T USB dongle from ebay. I was inspired by several stories found on the internet how to use it as a primitive SDR (software-defined radio). Somehow I didn’t get around to do anything with it, partly because most of the instruction in net were for windows based PC’s and those I found at that time for linux were command line programs.
Ubuntu releases 2 new versions every year, in April and October. About one and an half year ago I got fed up and decided to update only when a long term support version is released. In synaptic you can choose to get notifications only for LTS versions. Here’s the Ubuntu release timeline.
