IC-R2 Quick Ref
This page shows how to do the basics with the ICOM IC-R2.
The manual describes more, but it lacks a "getting started" section,
which is what I've tried to do with this page.
Here's what you'll find in
this Quick Ref:
-
To turn the unit on or off, press the POWER button
(orange above), and hold it for a couple seconds.
-
Pressing the BAND button switches bands, but you can
tune to anywhere in the entire range of the unit from any band starting
point.
-
Turning the knurled knob at the top tunes the unit up and
down in fine steps. To go fast, press and hold the FUNC
key while turning the knurled knob.
-
The IC-R2 supports three basic receive modes, AM, FM or WFM
(wide FM). For FM radio control systems, make sure you've selected FM
mode, both while tuning manually and when you save presets. You will
pick up adjacent channels if you leave the receiver in WFM mode, which might
cause hunting around for "nonexistent interference"! Push
the MODE button to switch from AM to FM to WFM and back to AM.
-
The IC-R2 is always in one of two major modes, either manual
tuning or memory. To switch back and forth press the V/M button
to switch from manual tuning (VOR) to memory pre-set mode. This is the
thing that confused me at first, since you can manually tune once you've
pulled up a pre-set! If MR is lit up on the LCD (see #8 on the
drawing above), you're in memory recall mode, if it's not, you're in manual
mode!
TO CHOOSE A MEMORY BANK:
-
Set the unit to memory recall by pressing the V/M
button until MR lights up (#8 on the LCD drawing above)
-
Press and hold FUNC, and turn the knurled knob at the
top of the unit. As you turn the knob, you'll see the "bank
indicator" change (#7 on the LCD drawing above). As usual, the
memory bank numbering is done from the programmer's point of view, starting
with "Bank 0"! Sorry 'bout that, but that's the way it is...
The bank indicator will show either:
- nothing (you're in the first memory bank 1)
- 1, 2 or 3 (you're in the second, third or fourth memory bank)
- a small diamond with no number (you're in the fifth memory bank)
- a small diamond with 1, 2 or 3 (you're in the sixth, seventh or eight
memory bank)
TO CHOOSE A MEMORY CHANNEL ONCE YOU'VE CHOSEN A MEMORY BANK:
TO SAVE A MEMORY PRESET (by choosing the memory storage location
first):
-
Choose a memory bank (make sure MR is lit up when
you're done, as above)
-
Choose a memory channel in which to store the new settings
(as above)
-
Press V/M to switch back to manual tuning mode
-
Tune to the frequency you want, make sure AM/FM/WFM and any
other settings are set the way you want
-
Now press and hold FUNC, and then press and hold V/M-MW
for a second or two, until you hear a double-beep. Now your preset is
stored in the location you chose in step 2.
 NOTE: This method will ONLY
save to a memory storage location that has been previously programmed!
Use the next method for the first time saving to a memory slot.
TO SAVE A MEMORY PRESET (by choosing the receiving
frequency first, then the memory location):
-
Tune to the frequency you want, make sure AM/FM/WFM and any
other settings are set the way you want
-
Press and hold FUNC, and then tap V/M-MW. If
you did this right, when you let go of the V/M-MW button you should
see the MW indicator and the bank number flashing. If
not, and if you heard a double-beep, sorry, you just over-wrote the
bank/channel shown on the unit. (This is why I tend to do it the other
way - keeps me from shooting myself in the foot. However, this way
allows you to choose the memory slot after tuning, which is sometimes
handy.)
-
Choose a memory bank by pressing and holding FUNC
while turning the knurled knob
-
Choose a memory channel in which to store the new settings
by turning the knurled knob
-
Press and hold FUNC, and press and hold V/M-MW for
two seconds, until you hear the double-beep. You've now saved the preset in
the bank and slot chosen in step 4.
TO SCAN A BANK OF MEMORY PRESETS
-
Choose a memory bank (see "choose
a memory bank" above)
-
Press and hold the FUNC button, and tap the VOL UP
or VOL DOWN arrows
-
The IC-R2 will scan up or down the list of memory
presets. Each time an active signal is found, it will stop for a few
seconds and then continue. To stop scanning, press FUNC and VOL
UP or VOL DOWN again.
TO SCAN A FREQUENCY BAND
-
Set the IC-R2 to normal operation (MR not lit), by
tapping the V/M button until the MR indicator on the LCD is not lit
up.
-
Press and hold the FUNC button, and tap the VOL UP
or VOL DOWN arrows
-
The IC-R2 will scan up or down the current frequency
band. Each time an active signal is found, it will stop for a few
seconds and then continue. To stop scanning, press FUNC and VOL
UP or VOL DOWN again.
TO SCAN USING SCAN EDGES Note: Scan edges
is the ICOM word for scanning between two frequency end-points, rather than
scanning particular fixed frequencies. The IC-R2 configuration file on
this site has scan edge pairs pre-configured for several key RC frequency
ranges.
-
Set the IC-R2 to normal operation mode (MR not lit),
by tapping the V/M button until the MR indicator on the LCD is not
lit up.
-
Press and hold the FUNC button, and push BAND
while the FUNC button is held down. The display will show
either ALL, BAND or PROGnn, where nn is a number (e.g. PROG12). Turn
the knob until the display shows PROGnn with the scan edge pair number you
want to scan between (see the cheat sheet for some examples).
-
Press the BAND button (you'll see some frequency
other than the edge presets on the display, but don't worry...)
-
Press FUNC + VOL UP / DN to start scanning
between the low and high scan edge frequencies.
HOW TO STOP SCANNING! (You were wondering about this,
right?)
HOW TO CONTINUE SCANNING WHEN A SIGNAL IS FOUND
You may be scanning, and find a signal that you don't want to
listen to, and you don't want to wait through the 10 seconds (or whatever is
configured in the unit) for Scan Pause time. If this happens, just turn
the knob while the scanner is paused on the found signal, and it'll continue the
scan "past" the pause frequency.
