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”.
1

Setting Squelch with RAN codes and IDs
Squelch levels are set in the programming software and are activated in the Memory CH »Squelch Type field. The
figure on the following page shows how squelch opens with digital frequencies.
When the squelch type is set to OFF, only the frequencies have to match for two radios to open squelch and
communicate. RAN codes, Talk groups, and Individual radio IDs are ignored.
Using RAN squelch is similar to setting CTCSS tones in an analog radio. The frequency and the RAN code must
match before squelch will open. Set the squelch type to RAN to enable this feature.
To enable communication to be selective for Talk Group IDs or Individual IDs, set the squelch type to SEL. With this
setting the frequency, the RAN code, and talk group ID (or Individual ID) must match before squelch will open. If you
want to call an Individual radio that is also part of a talk group, you can press a key that has been programmed with
an Individual ID function.

Selecting Digital Features
The figure below shows the sequence for selecting digital features. Note: the UT-126 DSP option board must be
installed and the digital features enabled in the cloning software. The following table shows the digital features
available for an individual or talk group call. Note: All options display for both Individual and Talk Group calls.
