What is Covered in this Guide
This guide provides simplified step by step instructions for programming the enhanced digital/analog features in your
F3161/F4161 or F5061/F6061 radio. The programming information covers IDAS 6.25kHz digital programming,
including IDAS trunking.
IDAS (Icom Digital Advanced System) is a digital and analog land mobile radio system, using the NXDN™ 6.25kHz
digital modulation and common air interface protocol.
To use the digital features, your radio must have the UT-119/UT-126 accessory board installed and enabled, with the
current radio and UT firmware upgraded to the latest revision. Check the Icom knowledge base (from the B-B
website) for more details.
Explaining Digital Squelch
There are several settings that enable the squelch to open up in your digital radio:
RAN Codes
RAN Codes are digital equivalents to CTCSS tones used in analog radios. The codes are decimal, and range from 0
to 63. If you want squelch set so that it can receive all RAN codes, enter 0. This code allows all RAN calls to be
received and will transmit using the code that is programmed for transmit in that channel.
Unit (Individual) IDs
Individual IDs allow for selective calling and identification of who is calling.
Talk Groups
Talk Group IDs allow for selective calling to a preprogrammed group of radios. The “all call” ID is “0”.
