Icom IC-V82

Icom IC-V82 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Icom IC-V82 rather than just read about it. In short: The Icom IC-V82 is a VHF band handheld transceiver designed by Icom for radio amateurs and professionals who require VHF communication. Launched in 2004 and discontinued in 2014, the IC-V82 is still valued in the second hand market for a number of additional features such as the ability to convert it, by adding a module, into a digital device, which make it ideal for certain applications requiring voice and/or data…

Reference excerpt

The Icom IC-V82 is a VHF band handheld transceiver designed by Icom for radio amateurs and professionals who require VHF communication. Launched in 2004 and discontinued in 2014, the IC-V82 is still valued in the second hand market for a number of additional features such as the ability to convert it, by adding a module, into a digital device, which make it ideal for certain applications requiring voice and/or data encryption.

Features It is a portable VHF transceiver with coverage in the two-meter band (144–146 MHz) and a maximum output power of 7 watts. It was manufactured and sold by Icom from 2004 to 2014.

frequency : VHF 136-174 MHz output power : 7 W (high), 4 W (medium), 0.5 W (low) modulation : FM (Frequency Modulated) channel memory : 207 channels screen : LCD with backlight battery : BP-222N (Ni-Cd) or BP-227 (Li-Ion)

Digital Module One of the most outstanding features of the IC-V82 is the ability to convert it into a digital device using the additional UT-118 module sold by Icom Inc. This module allowed the addition of advanced digital communication and encryption capabilities, including a trunking DMR protocol, digital voice communication and low-speed data in D-STAR format.

History In June 2022, United Against Nuclear Iran, a U.S. advocacy organization, identified the Icom IC-V82 as being used by Hezbollah, a U.S. designated Foreign Terrorist Organization. It sent a letter to Icom outlining its concerns about the dual-use capability of the transceiver (analog+encrypted-digital) and regarding Icom's business ties to Power Group (Icom's representatives in Lebanon) and Faza Gostrar, which claims to be the "Official ICOM representative in Iran". Many of the devices purchased by Hezbollah that later played a role in the 2024 Lebanon electronic device attacks, killing at least 25 people and wounding over 708, were reported as being IC-V82s. Icom opened an investigation into the case on 19 September 2024, while a sales executive at the company's U.S. subsidiary said the devices involved appeared to be counterfeit units.

Counterfeit models and controversy After Icom discontinued the IC-V82 in 2014, counterfeit models emerged in China. In addition, another counterfeit model was sold to Hezbollah, and many of the devices used by this group, including pagers like the Gold Apollo AR924, were exploded on 18 September 2024. Having ceased its production, Icom issued an advisory warning about counterfeit transceivers, including the IC-V82. In October 2018, the company issued a cease-and-desist order against a Chinese manufacturer suspected of producing counterfeit Icom products; it also noted that this was not the first time it had taken such steps.

Protocols

IIDAS IIDAS is Icom's implementation of the NXDN protocol for two-way digital radio products intended for commercial private land mobile radios (PLMRs) and low-end public safety communications systems. NXDN is a Common Air Interface (CAI) technical standard for mobile communications. It was jointly developed by Icom and Kenwood Corporation.

D-STAR The "open" D-STAR radio system was developed by Icom based on digital radio protocols developed by the Japan Amateur Radio League and funded by the Ministry of Posts and Telecommunications of Japan. This system is designed to provide advanced voice and data communications over amateur radio using open standards.

Accessories and options The IC-V82 has a variety of accessories that improve its functionality and ease of use:

Antenna : High gain antenna to improve reception and transmission. Belt Clip : For comfortable and safe transport. Optional batteries : Available in different capacities and technologies (Ni-Cd, Li-Ion).

Worked examples

Example 1 — a first encounter with Icom IC-V82

Start with the simplest possible case. Write down what Icom IC-V82 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Icom IC-V82 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Icom IC-V82 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Icom IC-V82

In research: Icom IC-V82 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Icom IC-V82 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Icom IC-V82 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amateur radio transceivers, Consumer electronics, Israeli–Lebanese conflict, so understanding it makes those chapters shorter.
In everyday life: Look for Icom IC-V82 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
