Chapter 7. - Selective calling
Some times when you're working with larger groups of people using the same channel, things
can get very crowded, very fast. To minimize this problem, several methods of blocking out
unwanted transmissions on your frequency have developed. In general, there are two forms of
selective calling in two-way radio systems: Group calling, and individual calling.
Group calling, as the name suggest, is a one-to-many form of communication. Every radio in
your working group is configured the same way and any radio will make contact with every other
radio in the group.
Individual calling, some times also known as paging, is a one-to-one form of communication.
Every radio is programmed with a unique ID code. And only by sending out a matching code
can you get that radio to open up to your transmissions.
The BTECH X-SERIES MOBILES features three additional ways of group calling
(2TONE, 5TONE, AND DTMF CALLING ARE FOUND IN CHAPTER 5):
• CTCSS
• DCS
