same way and any radio will make contact with every other radio in the group.
Individual calling, sometimes 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 radio features three different ways of group calling:
• DCS
• CTCSS
• Tone-burst (1750Hz)
The radio does not feature any form of individual calling.
Using these features does NOT mean that others won't be able to listen in on your transmissions.
They only provide a method to filter out unwanted incoming transmissions. Any communications made while
using these features will still be heard by anyone not employing filtering options of their own.
Also, you cannot change the DCS or CTCSS settings while in memory (MR) mode.
CTCSS and 1750Hz tone-burst are also popular methods among amateur radio operators to open up repeaters.
