The IC-9100 is Icom's one-box, do-everything base transceiver from the early 2010s — HF through 6 meters, 2 meters and 70 centimeters all-mode in a single chassis, with 1.2 GHz (23 cm) available if the optional UX-9100 band unit is fitted. Think of it as an IC-746Pro-class HF radio and a serious VHF/UHF weak-signal and satellite radio sharing the same box, the same large monochrome LCD, and the same 32-bit floating-point DSP. It puts out 100 W on HF/6 m and on 2 m, 75 W on 70 cm, and 10 W on 23 cm with the UX-9100, and it has two independent receivers so you can listen on two different bands at once — HF + VHF/UHF, VHF + UHF, or 70 cm + 23 cm. There's a built-in automatic antenna tuner for HF/6 m, a built-in RTTY demodulator/decoder that reads on the display, and a single USB connection on the back that carries rig control (CI-V), transmit/receive audio, and RTTY output to a PC — no separate interface box needed for digital modes. What makes it good is that the VHF/UHF side is not an afterthought. Owners and reviewers consistently rate the 2 m / 70 cm / 23 cm performance — satellite work, moonbounce, weak-signal SSB and contesting — as the reason to buy one, with a dedicated satellite mode that synchronizes uplink and downlink, tracks in the same tuning step for normal and reverse-mode satellites, eases Doppler compensation, and stores 20 satellite memories. The HF receiver borrows from Icom's higher-tier HF line: double-conversion superheterodyne (triple-conversion on 23 cm), +30 dBm (typ.) third-order intercept on HF, digital IF filters you can shape yourself, twin passband tuning, and slots for two optional first-IF roofing filters — the FL-430 (6 kHz) and FL-431 (3 kHz) — on top of the built-in 15 kHz filter. Add D-STAR DV if the optional UT-121 module is installed (usable on 2 m, 70 cm and 23 cm, plus 10 m and 6 m simplex), and one radio can cover DX, RTTY, satellites and D-STAR without swapping rigs. Buying used, the options are the whole story — and they're the first thing to verify, because a bare radio and a fully loaded radio are very different values. Ask explicitly, and ideally see it shown on the display or in photos: (1) Is the UX-9100 1.2 GHz unit installed? (2) Is the UT-121 D-STAR unit installed? (3) Are the FL-430 and/or FL-431 roofing filters fitted? None of those three was standard. Beyond options, check the known quirks: early lab testing and owner reports document SSB ALC overshoot that can trip or stress solid-state amplifiers (one owner reports it repeatedly tripping a 1 kW Beko amp on 2 m) — ask whether the radio has had Icom's ALC fix and test it into your amp at reduced drive first; listen for fan behavior (the fan is described as loud and, after a 2 m transmit session, can run on for a long time); watch the LCD at power-on for slow backlight illumination or display/inverter trouble, both mentioned by owners; and remember power is set as a single percentage across bands with no per-band power memory, so confirm full output separately on HF, 2 m and 70 cm. Finally, test the USB port with a short cable — and a powered hub if the connection drops — because owners have traced intermittent USB audio/control dropouts to the radio's internal USB hub browning out on low-current PC ports.
You don't need the Signalink — the equivalent is built in. A single USB (Type B) cable between the radio and PC gives you rig control via CI-V plus transmit and receive audio. In WSJT-X / digital software select the radio's USB Audio Codec, use the data mode — D-USB (Digital USB), not plain USB — so the compressor and TX/RX tone shaping are switched off, and set the radio menus to match the software. WB4SON's working starting point: Menu 59 DATA MOD = USB, Menu 58 DATA OFF MOD = MIC, CI-V baud 19200, CI-V address 7Ch, and USB MOD Level around 25%, trimmed until the meter shows zero ALC on transmit — the adjustment is very touchy (in his case 27% already showed mid-scale ALC, which distorts the signal).
In almost every case it's a settings mismatch, not a fault. Check three things: (a) PTT method — the software must key the radio by a CAT command, or you must use VOX, which is fussy about audio level; (b) modulation source — with DATA MOD set to USB the radio takes audio from the USB port only in data mode, so confirm you're actually in D-USB/D-LSB and that Menu 59 points at the port you're feeding; (c) drive level — set USB MOD Level for zero ALC (see FAQ 1). If it keys but shows no output, the modulation source is almost always set to the mic when the audio is arriving on USB, or vice versa.
No — neither is standard. D-STAR DV voice and low-speed data requires the optional UT-121 D-STAR unit; without it the radio does SSB/CW/AM/FM/RTTY only. 1.2 GHz (1240–1300 MHz, 10 W) requires the optional UX-9100 1200 MHz band unit; without it there is no 23 cm transmit or receive and no 23 cm antenna connector in use. The two HF roofing filters are also options: FL-430 (6 kHz) and FL-431 (3 kHz). Because all four were extra-cost when new, always confirm what's actually fitted before comparing a used price to other IC-9100s — the ledger shows installed options are the biggest driver of what a given unit sells for.
