The ICOM IC-7410 is the now discon-
tinued IC-746PRO writ larger — at least
physically, since this radio does not in-
clude 2 meter capability. In nomenclature
it follows the IC-7400, never marketed in
North America but which served as the
IC-746PRO in other parts of the world,
including Europe.

ICOM continues to
capitalize on this excellent and popular radio
foundation with the nearly simultaneous
release of the IC-9100, a higher tier model
that does include 2 meters, 70 cm, an optional
23 cm module, satellite features and a heftier
price tag. So, you could say the IC-7410 is
the IC-9100 for the rest of us.
ICOM’s description of the IC-7410 as
“an excellent balance of technology and
performance” may suggest some measure
of compromise, but it’s quite capable. Keep
in mind, too, that ICOM has incorporated
the incremental technological improvements
— faster signal digital signal processing, no
waiting for the radio to “boot up,” for instance
— that have been showing up in offerings
preceding the IC-7410, such as the IC-7600.
What’s It Like?
Given its slenderized form factor you
could find yourself doing a bit of juggling to
fit the longish IC-7410 comfortably on your
operating desk. It’s narrower by about an
inch from the IC-756PRO series or IC-7600
models, but it’s certainly deeper. I managed
to perch it atop my IC-756PROIII, so I could
do some side-by-side (so to speak) compari-
sons, but I ended up using a mirror to locate
rear-panel connector since the newer radio
extends about two inches beyond the edge
of its older relative.
The ’7410 offers a pleasing countenance,
with a 10.25 × 6 cm monochrome display
window, accented on the left and bottom
edges with an inset ogee-style half frame.
This is not the more commodious color dis-
play of the IC-7600 or even of the PROIII,
but it is quite sufficient. The IC-7410’s
frequency readout seems larger than life
within the slightly smaller display screen.
The metallic F-1 through F-5 buttons imme-
diately below the display window are easier
to differentiate from the MODE buttons that
I am always pressing in error on my PROIII.
ICOM slightly offset the function buttons
from the five MODE buttons, to minimize
this possibility on the ’7410.
The hefty main tuning knob possesses the
sort of solid counterbalanced feel that puts the
The IC-7410 replaces the
IC-746PRO and adds an improved
receiver, much faster DSP perfor-
mance and new features to the mix,
but drops 2 meter coverage. Although
the new radio does a lot, the ’7410
user interface will be familiar to
users of current ICOM radios.
