'''A Few Notes Before you Begin'''


Before you jump in and make your contribution, please first familiarize yourself with the layout of the site. Doing so will help you to place your information in the right location. As the wiki grows, it takes an increasing amount of effort and discipline to keep it from quickly turning into a tangled mess. So it's up to each of us to make sure the information submitted is easy for everybody to find and access.

In electronics, tuning refers to a process in which, first, a specific [[RF]] signal is acquired and, second, is subsequently acted upon such that any underlying content (information/data) may be extracted.

Would like to try to setup a table for the chipsets using templates such that, with using logic to define relevant fields, we have all the data contained in one spot (I guess much like Henrik was doing with the DVB-T USB stuff), but can then parse the info for display in relevant articles, such that there isn't duplication.
