Icom IC-7000 QST Review

PRODUCT REVIEW
Reviewed by Mark Wilson, K1RO QST Product Review Editor
It’s hard to believe that 10 years has passed since QST first reviewed the IC-706, calling it “one of the most ex­citing new products to come along in
1
years.”
The package proved a huge hit, and ICOM kept the radio fresh by following on with the IC-706MkII and IC-706MkIIG. By the time the G version rolled out in 1999, ICOM had added 70 cm, bumped up the power on 2 meters, made DSP noise reduc­tion and notch filter standard, and made quite a few improvements. Meanwhile, ICOM has been busy doing extreme makeovers on the rest of the product line, moving to DSP­based receivers and sophisticated display screens.
Which brings us to the IC-7000. Although the ’7000 is similar to the ’706 in many ways, it also shares features with the IC-756PROIII. ICOM touts the IC-7000 as a mobile trans­ceiver, but, like the ’706, it will find its way into many a suitcase for DXpeditions and Field Day outings. For a lot of hams, it has everything they want and need in a home station radio.
Feature Overview
The IC-7000 covers 160 meters through 70 cm except for 1.25 meters. Power output is 100 W on 160 through 6 meters, 50 W on 2 meters and 35 W on 70 cm. The radio works on the five 60 meter channels available to US operators, and it transmits only when one of those channels is precisely dialed in. The receiver covers 30 kHz to 200 MHz and 400 to 470 MHz. Modes include SSB, CW, AM, FM and RTTY. The receiver has WFM for listening to FM broadcast stations and TV audio.
DSP features include selectable IF filters, adjustable AGC, noise blanker and noise reduction, passband tuning, an automatic notch filter and a two point manual notch

filter. In addition, the ’7000 offers a CW memory keyer, RTTY demodulator and digi­tal voice keyer. FM features include scanning, automatic repeater offset, subaudible tones, DTMF memories and other familiar features. Gadget junkies will love this radio.
Hooking it Up
The package is compact and feels quite solid. It’s the same height and width as the IC-706 but not quite as deep. There’s a folding bale on the bottom for desktop use, and the speaker and small fan are both on top. The front panel detaches and ICOM offers several different brackets and separation cables for mobile use.
The radio needs about 22 A at 13.8 V dc. The supplied HM-151 mic plugs into one of two modular jacks — one on the bottom edge of the front panel, the other on the back of the main unit. (You can’t use two microphones simultaneously, though.) A the right edge of the front panel works with stereo or mono headphones or an external speaker thanks to a switch behind the front panel.
The rear panel will be familiar to IC-706 users. There are two antenna jacks, one for 160 to 6 meters and the other for 2 meters and 70 cm. There’s a

A matching plug is wired with short pigtails — no soldering to minuscule pins! The 6-pin also be used for connecting a TNC or sound card for digital modes. Note that the IC-7000 can handle amplifier key lines up to 16 V dc at 200 mA. Some amplifiers will require a separate keying interface with higher ratings to avoid relay damage.

That Colorful Display
Everyone who used the review radio raved about the ’7000’s color TFT display screen. It measures 2.5 inches diagonally, and is about 2 inches wide by 1.5 inches tall. Before the radio hit the streets there was some trepida­tion about the readability of such a small, busy display. Let’s face it — many hams (including me) are at the age where things look a little fuzzy and we need to break out the reading glasses when QST arrives.

Those fears were completely unfounded. The incredible resolution, bright colors and excellent contrast make the display easy to read under a variety of lighting conditions and viewing angles. The characters are crisp and clear, and everyone who used the radio could easily see and use the screen labels and graphics. Sure, in a mobile environment or outdoors on a bright day it’s occasionally dif­ficult to see the display, but I found it perfectly readable under most conditions.
One of the menus allows you to change display characteristics such as brightness and contrast. Most photos show the default black background with white lettering, but you can change it to a bright blue background with white letters or a white background with blue letters.
The rear panel earlier is an analog video output. For grins I plugged it into the composite video input on my TV, and the IC-7000’s display im­mediately filled the screen. While this might be useful for a presentation, you’re more likely to hook up one of those small video screens made for portable DVD players or automobile entertainment systems. Note that the composite video output isn’t as crisp as the internal display.
Controls and Menus
Although the ’7000 takes some getting used to, ICOM did a good job with the human interface despite a minimum of buttons and panel space to work with. Most buttons have multiple functions, and some menus and con­trols change according to mode of operation. For the most part I was able to figure out the functions, but I kept the manual close during initial operation.
The main tuning knob has a nice feel. The
BAND
hand corners. Pressing one or the other will bring you to the last-used frequency on each band. I like to chase DX on various bands and modes and have grown fond of the band stack-
up and down switches are at the right-
ing registers on my desktop radio. Repeatedly pressing a band button on the keypad jumps me from SSB to CW to RTTY subbands with filter selection and other settings ready to go. ICOM has added this convenience to the IC­7000 through the HM-151 microphone. The mic’s keypad resembles the keypad found on the front panel of larger radios and works the same way. There’s a button for each band, and repeated pressing steps you through three band stacking registers. The keypad also works for direct frequency entry. Other HM­151 buttons control common functions.
As mentioned before, there are two mic jacks but you shouldn’t plug in two micro­phones at the same time. For home station operation with a desk mic or headset it would be nice to plug in a keypad with the HM-151 functions, or else be able to disable the HM­151 mic element and use it as a keypad.
