Icom IC-7100 Review

A fully-featured tri-band radio that also offers amazing D-STAR compatibility? Who could say no? The Icom IC-7100 may be a little bit expensive, particularly for new ham operators. But it justifies its price tag with robust features, excellent sound quality, and a surprisingly small learning curve, especially for those who have already used Icom products in the past.


  • Great display with excellent touchscreen – It may not be full color, but the LCD touchscreen is large and responsive, making for an excellent user experience. It even functions while wearing gloves, which makes it ideal for use while working outdoors in cold conditions.
  • Intuitive detached control head – The angled control head may look a little bit funny at first, but it’s got great ergonomics. And, despite its light weight, durable rubber feet keep it from moving around during routine use.
  • Excellent D-STAR capabilities – The IC-7100 is an excellent choice for any ham looking to dabble in digital radio. It supports both DV mode digital voice and low speed data communications. While it doesn’t come with a GPS, it can be expanded with a variety of compatible units for further functionality.
  • Tri-band design with plenty of power – Maximum transmit power is up to 100W in HF bands, 50W in VHF, and 35W in UHF. Paired with the proper antenna and accessories, this powerhouse will have you reaching repeaters and base stations worldwide.
  • Powerful DSP for clear audio – The proprietary digital signal processing (DSP) uses a 32-bit, floating point architecture to provide clean, crisp audio on both digital and analog bands.
  • 500+ memory channels – The IC-7100 supports 495 standard channels, 4 call channels, and 6 scan edge channels, as well as 900+ DR mode repeater channels for D-STAR users.


  • Lacks a few features compared to the competition – Some comparable radios in this price range have features like a GPS, color screen, and built-in antenna tuner, which the IC-7100 lacks.
  • Touchscreen quality control – A handful of users have noted that they’ve experienced malfunctioning touchscreens or complete touchscreen failure. You may want to keep this in mind while shopping.

Bottom line

This is a great mobile transceiver, particularly for newer operators who may have mostly used HTs, but are now familiar with the basics and are ready to set up a home base station or a mobile vehicle station. It’s not cheap, but the Icom IC-7100 has tons of amazing features and is built to last, making it a good overall investment.

Expert reviews

  • In a video review, Eric from Ham Radio Concepts reviewed the Icom IC-7100, which he purchased for his personal ham shack. He called it a “great radio” for anyone wanting to get into HF, VHF, UHF, and D-STAR all in a single radio. He mentioned that it was a great radio both for new amateur radio operators, and for veterans who are looking for more advanced features in a desktop or mobile radio.
  • Jarrad from Rate My Radio did a “mini-review” of the IC-7100. He called it “quite well priced” and noted a few other highlights, including the angled and easy-to-store remote control head, the intuitive mounting design, and the design that uses shielded RJ45 connectors to prevent RF interference. Overall, he said he has “loved the radio” ever since he bought it, saying it’s “very well made.”
  • British blogger Tom McQuiggan reviewed the ICOM IC-7100 in a blog post, calling it a “fantastic option” for people who are looking for their first radio, particularly when purchased second-hand. Among other features, he had good things to say about the intuitive, touchscreen-enabled control head, the “shack in a box” HF/UHF/VHF/D-STAR capabilities of the unit, and the excellent noise reduction features of the IC-7100.

User reviews
