frequencies by MHz to speed the process.
From a convenience standpoint, it’s for-
tunate that the IC-R6 is loaded with memory
channels more than 1300 of them. It is
easier to flip through these channels, which
can also be organized by band or activity,
than it is to rely on VFO tuning. The radio
arrives with weather, marine and a slew of
shortwave broadcast frequencies prepro-
grammed. You can populate the remaining
memory slots in several ways. One
method is to manually dial up your de-
sired frequency and write it to memory.
You can add an alphanumeric tag for
easy reference later. Another approach
is to allow the IC-R6 to scan a given
frequency range and automatically
fill the memory channels with any
signals it finds. The IC-R6 offers
extremely fast scanning, on the order
of 100 channels per second.
My preference was to invest
in the ICOM OPC-478UC USB
“cloning cable” and do the mem-
ory programming from my laptop
computer. This turned out to be
the easiest method by far. Using
the ICOM CS-R6 software for
Windows (Figure 1), I was able to

Bottom Line
Reviewed by Steve Ford, WB8IMY

My very first receiver, the one that
introduced me to the strange noises being
generated by people who called themselves
“hams, was a monster. The Hallicrafters
S-40B was a hulking black box that tipped the
scales at something in excess of 25 pounds.
Fast forward 40 years and the breakneck
evolution of technology has turned the
S-40B and radios like it into little more than
beloved curiosities. Over the years we’ve
seen radios become ever smaller thanks
to astonishing progress in semiconductor
technology combined with ultra-miniature
surface-mount components. The new ICOM
IC-R6 portable receiver is an example of
how far weve come. My S-40B has ef-
fectively shrunk to a pocket sized box that
weighs less than 8 ounces. Moreover, its
frequency coverage has expanded from
the depths of longwave to the rarified at-
mosphere of microwaves. And then there
are the IC-R6 memories, multiple scanning
functions and well, at least the S-40B still
retains its nostalgia value!
Tiny Package, Large Feature Set
The ICOM IC-R6 is a wideband AM
and FM receiver that covers 100 kHz to
1300 MHz (cellular telephone frequen-
cies blocked, of course). At first glance it
looks like a handheld transceiver complete
with a rubberized PTT button on the side.
That actually serves as the FUNCTION and
SQUELCH/MONITOR switches. The antenna
connector is a female SMA; it sits next to
an earphone jack that doubles as the data
port. The knob on top is normally used to
change frequencies or memory channels.
UP and DOWN buttons on the front panel
control the audio volume, although you can
use the IC-R6 menu options to switch the
volume adjustments to the knob and assign
frequency tuning to the UP/DOWN buttons.
The IC-R6 offers a variable frequency
oscillator (VFO) tuning function, but this
works best when you’re navigating a limited
range of spectrum within a given band. There
is no way to easily enter a specific frequency
directly. Instead, you must first navigate to
the desired band, then twist the VFO knob
until you see the desired frequency on the
liquid crystal display (LCD) you can step

read the contents of the receiver’s memory,
modify the contents (or add new frequen-
cies) and then write everything back to the
radio. You can organize the entire memory
array any way you desire, add alphanumeric
channel labels, select tone squelch frequen-
cies and designate particular channels to be
skipped while scanning.
Power Options
The IC-R6 is supplied with two AA size
NiMH rechargeable batteries and a small
wall charger. If you wish, you can swap the
rechargeable cells for AA alkaline batteries,
but I found that the NiMH cells provided
plenty of listening time.
When it comes to charging batteries
in the IC-R6, it is important to read the
manual. If the batteries are being charged
for the first time, or if you’ve removed the
batteries for longer than two seconds, you
have to go through a multi-step process to
place the receiver in the charging mode. I
skipped this page in the manual and found
myself frustrated with what I thought was a
defective charger!
It is worth noting that there is a drop-in
charger option for the IC-R6 — the ICOM
BC-194. However, I didn’t have the unit to
test for this review.
Surfing the Ether with the IC-R6
One of the first things I discovered about
the IC-R6 didn’t come as a surprise. The
radio is supplied with a 6 inch flexible
rubber antenna. This antenna is fine for
local VHF/UHF signals, but woefully
inadequate for shortwave listening. If you
confine yourself to the stock antenna, you
may hear a few of the louder shortwave
broadcasters, but not much more.
Adding a longer antenna makes a world
of difference. I had a 4 foot telescoping whip
antenna that I attached to the IC-R6 by way
of a connector adapter to go from the whip’s
BNC connector to the radio’s SMA connec-
tor. Such adapters are available from many
dealers. Alternatively, you can use the IC-R6
option menus to switch the external antenna
from the SMA jack to the earphone cable.
Thats right; the IC-R6 has the ability to turn
your earphone or headphone cord into an
antenna. If you don’t have a longer antenna
at hand, this option is vastly superior to the
flexible antenna for shortwave listening.
