The Icom IC-7100 is a 100 watt HF/50/144/430 MHz all-mode amateur transceiver with D-STAR digital voice, a detachable touch-screen control head, and 32-bit IF DSP. It transmits 100 W on 160 through 6 meters, 50 W on 2 meters, and 35 W on 70 cm from a single 13.8 VDC radio, which makes it a common pick for operators who want one rig for mobile, base, portable (POTA/SOTA), and emergency communications.

What's in the box
IC-7100 main unit, touch-screen controller, HM-198 hand microphone, OPC-2253 controller separation cable, DC power cable, 13-pin ACC cable, USB cable, ferrite EMI filter, key plug, microphone hanger, and spare fuses. Icom no longer ships a printed or CD manual; the current manuals are available for download from Icom.
Who the IC-7100 is for
Mobile operators: The main unit mounts under a seat or in the trunk while the controller, which carries the speaker and the mic, key, and headphone jacks, sits where you can reach it.
One-radio stations: HF, 6 m, 2 m, and 70 cm in one box, including VHF/UHF all-mode for SSB and CW weak signal work, not just FM.
Digital mode and EmComm operators: USB audio and CAT control run FT8, Winlink, and JS8Call without an external sound card interface, and you can move from HF SSB to a VHF packet or Winlink path on the same radio.
D-STAR users: DV mode digital voice and low speed data on 2 m and 70 cm, with DR mode for repeater and reflector routing and a repeater database that can search by location when paired with an external GPS.
Know before you buy
No internal antenna tuner. Plan on a matched antenna or an external tuner such as the Icom AH-4 or AH-730.
No real-time spectrum scope or waterfall. If a panadapter is a requirement, pair the radio with PC software or look at an SDR-based radio.
Desk-angled controller. For dash mounting, the optional MBF-1 suction mount or MBA-1 controller bracket is the usual solution.
License required to transmit. An FCC Technician license covers 6 m, 2 m, 70 cm, and limited HF. A General or Amateur Extra license is needed for most HF voice privileges.
Frequently asked questions
Does the Icom IC-7100 have a built-in antenna tuner?
No. The IC-7100 does not include an internal tuner. Icom's AH-4 (for wire and long antennas) and AH-730 are the common add-on tuners, or you can use any external tuner rated for 100 W.
What power supply does the IC-7100 need?
A 13.8 VDC supply rated for at least 25 A continuous. The radio draws up to 22 A on transmit at full power, and a supply with headroom runs cooler during long digital mode sessions.
Can the IC-7100 run FT8 and other digital modes?
Yes. The built-in USB port carries both audio and CI-V rig control, so one cable to a computer is enough for WSJT-X (FT8, FT4), Winlink, JS8Call, fldigi, and logging software. Install the Icom USB driver before connecting.
Which bands does the U.S. IC-7100 cover?
It transmits on 160 through 6 meters including 60 m and the WARC bands, plus 2 meters and 70 cm. It receives from 0.030 to 199.999 MHz and 400 to 470 MHz. The 4 m (70 MHz) band is only on European versions.
Does the IC-7100 support D-STAR?
Yes. DV mode digital voice and low speed data work on 2 m and 70 cm, with DR mode for repeater and reflector routing. An external GPS receiver or manual position entry enables location-based repeater search and position reporting.
Can I operate the IC-7100 remotely?
Yes, with Icom's optional RS-BA1 IP remote control software. The IC-7100 has no network port of its own, so it connects by USB to a PC at the station, and that PC handles the network connection to your remote computer.
Should I buy the IC-7100 or wait for the IC-7110?
Icom announced the IC-7110 as the IC-7100's successor at the Tokyo Ham Fair on August 29, 2026, with an SDR receiver, spectrum scope and waterfall, and a color touch screen. As of September 2026, Icom has not published a U.S. release date or price. The IC-7100 is available now, has more than a decade of field use behind it, and has a full accessory and replacement parts ecosystem. If you need a radio now, the IC-7100 is a proven choice.
Is the IC-7100 good for mobile installs?
Yes. The detachable controller and 11 ft separation cable let you hide the main unit, and the controller houses the speaker and operating jacks. Use a fused power run direct to the battery and plan the controller mount before you drill.
Recommended accessories
13.8 VDC 25 A or larger power supply (such as the Icom PS-126), AH-4 or AH-730 antenna tuner, MBF-1 suction cup mount, MBA-1 controller bracket, SP-35 external speaker, RS-BA1 remote control software, and a replacement OPC-2253 separation cable for a second install location.
