The Nuts and Bolts

  • If you're a newcomer, you've probably already discovered that there's a huge amount of terms that seem unfamiliar to you. Our Glossary has lots of these terms, along with definitions. Just click on the term you wish to view.
  • When looking at frequencies in our database, float your mouse over the column header, and you should get a balloon with a brief description of the terms and abbreviations that are used there.
  • The biggest hurdle for many is the concept of trunking. Our Trunking Basics article will get you started, as well as this PDF file written by UPMan. Note that you will need Adobe Acrobat or a compatible reader (such as Foxit) to read it.

The Manuals Are Too Confusing. Anyone have anything that's easier to read?

  • Uniden did a fine job designing these radios. Too bad one cannot say the same about their manuals. Fortunately, there is another resource - loosely referred to as the 'Easier to Read' series, they have been generally lauded as being much more readable and understandable.
