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.
