Selcall Operation; General; Calling Operation; Tx Code Channel Selection - Icom IC-440 Instruction Manual

■ General

In addition to the tone squelch operation for silent stand-by,
the SelCall operation is available. SelCall is an abbrevia-
tion for "Selective Calling." In tone squelch operation, there
are 155 ways to make an individual call with CTCSS tone
frequencies/DTCS codes versus 100,000 ways to make an
individual call with SelCall using 5-tone.
SelCall allows you to selectively call another unit that is op-
erating on the same channel.
SelCall can also call the entire group on that channel using
tone squelch code.
The caller station code/name, Answer Back function, etc. are
available with SelCall operation. A variety of functions are
available depending on the setting with the CS-440
. See the help fi le for setting details.
