the IC-706's successor, touchscreen, D-STAR, 32-bit IF DSP, two antenna ports HF + 6m + 2m + 70cm all-mode + D-STAR DV digital voice touchscreen dot-matrix LCD on slanted controller (innovative angled design for viewing!) 32-bit floating-point IF DSP (digital IF filter, twin PBT, manual notch, NR, CW auto tune) DSP-controlled AGC loop (DSP processing feeds back to AGC, AGC works on intended signal only) D-STAR built-in: DV digital voice + ~950 bps slow-speed data (DV only; no DD mode; DD/128 kbps needs 1.2 GHz, which the IC-7100 lacks) D-STAR features: call sign routing, repeater linking, GPS position reporting, DR mode (D-STAR Repeater easy mode) TWO separate antenna connectors: HF/6m + VHF/UHF on separate SO-239 jacks separate main unit + controller design (3.5m/11ft OPC-2253 separation cable included) built-in speaker on controller unit SD card slot (voice recording, D-STAR capture/playback, settings backup, clone) 505 memory channels ±0.5 ppm frequency stability SWR graphic display variable power output multi-function meter (power, SWR, ALC, compression, voltage, current, temperature) USB connector for CI-V control + audio in/out (built-in USB sound card!) optional RS-BA1 IP remote control (operate from PC over internet/LAN) HM-198 hand mic + USB cable + separation cable + DC cable + spare fuses included DISCONTINUED

Strengths

A compact IC-706 successor (now discontinued) with a touchscreen, built-in D-STAR, 32-bit IF DSP with DSP-AGC, and two antenna ports. The built-in USB sound card needs no external interface for digital modes, with an SD card, RS-BA1 remote, and a separate main unit plus controller. It runs 100W on HF, adding everything the IC-7000 did plus D-STAR, a touchscreen, and USB audio.

Weaknesses

$900-1200 new (the IC-7000 was cheaper). D-STAR only (no DMR or C4FM). The touchscreen is resistive (not as smooth as a phone). The controller speaker is small. No built-in ATU (the AH-4 is external). No waterfall display. 35W on 70cm (the IC-9700 does 75W). A dot-matrix display (not full-color TFT like the IC-7300).

Verdict

A discontinued all-band workhorse. The IC-7100 was the modern IC-706: HF through 70cm, all modes including D-STAR, a touchscreen, 32-bit IF DSP, and USB audio in a compact mobile/base package. The built-in USB sound card means FT8 and other digital modes work with just a USB cable. For one radio covering HF, VHF, UHF, analog, and D-STAR, it was Icom's compact all-band answer.

The Icom IC-7100 is a multimode HF, 6-meter, 2-meter, and 70-centimeter transceiver best known for its unusual sloped, detachable controller and its touch-screen interface. It outputs 100 watts on HF, 50 watts on 2 meters, and 35 watts on 70 centimeters, and operates SSB, CW, RTTY, AM, and FM, plus Icom's D-STAR digital voice mode, which made it a popular gateway into digital amateur radio.

The angled control head was designed to sit naturally on a desk or vehicle console, with the main body mounted remotely. A 32-bit floating-point DSP drives digital IF filtering, twin passband tuning, and manual notch filters, giving it modern signal-processing performance in a radio aimed at mobile and base use alike. The combination of all-band, all-mode coverage with D-STAR in one affordable box kept it in Icom's lineup for over a decade.

Icom discontinued it (it is now listed as discontinued on Icom's site), so it is found as remaining or used stock. Compare it with the IC-7000 and the classic IC-706MKIIG.
