Icom IC-R20
On receipt of the Icom IC-R20 I had a few questions that I wanted answering
such as Have they made a decent belt clip for it? Will the bank linking shortcomings
be sorted? What was the CTCSS/DCS features like? Has the priority feature been
bettered? Well all will be revealed.
Features
The Icom R20 comes with all the features found on earlier models of mini scanners
from Icom (R2 and R5) such as ctcss dcs duplex operation etc. However for me
the most exciting addition comes in the form of audio recording, in excess
of 4 hours worth in fact. This I was really keen to give a try out.
100 channel/sec, high speed scan
The IC-R20 has a 100* channel/sec, ultra high speed scan capability. Good this
is an improvement over the previous mini scanners I have owned from Icom.
Auto memory write scan
Auto memory write scan for a signal, when a signal is detected the received
frequency is automatically stored onto an auto memory write channel bank.
Up to 200 auto memory write channels are available.
Total of 1250 memory channels, 26 memory banks with 8-character comment
The IC-R20 has 100 regular channels (includes 10 pre-set channel), 50 scan edges,
200 auto memory write scan and 70 TV (audio) channel memories. Each regular
channel stores an 8-character alphanumeric name, including 5 icons, modes,
tone frequency, skip information and so on. Icom’s DMS (Dynamic Memory
Scan) system divides these memories into 26 groups, A to Z, and allows you
to scan selected banks by simply adding and deleting bank links. The Pre-set
channel memories up to 10 of your favourite channels for easy recall. In addition,
TV channels and short wave broadcast stations are pre-programmed.
11 hours* of continuous receive capability
The IC-R20 has a very effective power saving design for long operation. A
lithium-Ion battery pack, BP-206 provides 11 hours of continuous receive*
and when used with the power saving function, longer operating periods are
possible. Power by AC adapter or optional cigarette lighter cable is also
possible and the Li-Ion battery pack is simultaneously charged during operation.
Built-in ferrite bar antenna for AM and earphone cord antenna for FM broadcasts
A built-in ferrite bar antenna clearly catches AM broadcast stations with good
sensitivity. When you listen to FM broadcast stations with the optional earphone,
SP-13, the antenna type is selectable from cord or whip in set mode.
VSC, CTCSS and DTCS tone squelch
The VSC (Voice squelch control) opens the squelch only when a modulated signal
is detected and ignores un modulated, beat noise signals. The CTCSS and DTCS
tones provide quiet stand-by while waiting for a matched tone signal. This is
convenient for monitoring a specified repeater, station, etc. Tone scan detects
a tone frequency used in a channel. The pocket beep function alerts you with
a beep sound when a matched tone signal is received.
Useful bandscope
Easily find busy channels or unoccupied frequencies within a specified bandwidth
(from 1 kHz to 100 kHz). All signals are visually shown on the screen and AF
output is emitted while sweeping the range.
PC programming capability
With the optional CS-R20 cloning software, memory contents such as frequencies,
channel name, bank name, set mode items, etc can be easily programmed. A USB
cable is supplied with the CS-R20 to enable you to connect to a PC.
Noise reduction functions
- Noise blanker (SSB, CW)…Eliminates pulse type noise.
- ANL (Auto Noise Limiter, AM only)…Reduces noise components.
- AF Filter…A low pass filter for suppressing high tone audio, and reduces
high tone distortion.
- Attenuator and RF gain control…30dB (approx.) of attenuator and RG gain
control are built-in.
Looking at these features this hopefully should make for a very versatile
scanner. So then on with the review.
First Impressions.
The first thing that struck me was the size of the R20, I was expecting something
larger than what I was looking at which
was a bonus for me as after owning an R2,R5 and yaesu vx5 I was sort of used
to using the smaller scanners. This does not mean that the R20 falls into the
category of miniature scanners though by any means, but it is an acceptable
size. I wont go into all the buttons you can see on the keypad as I think
the images below will be self explanatory. However I will mention the bottom
row. As I have already mentioned the R20 comes with an audio recording facility
and these buttons are akin to the buttons you would see on a tape recorder
and they more or less work the same as the ones on a tape recorder. (Read more
in the audio recording section below.)
The R20 is also an acceptable weight (See specs below) so you are not forever
pulling your trousers up due to excess weight when attached to a belt. Which
brings me to the next point. The belt clip. This is a vast improvement to the
one supplied with the r2/r5 models which were prone to breakages and took some
force to hook over a belt clip or top of your trousers. The only drawback of
the belt clip is it makes the unit top heavy when stood on a hard surface and
I was constantly having to stand it back up after it toppled over backwards
a few times. This can be remedied by being very careful how you stand the R20
up.The belt clip utilises a spring loaded alligator clip format like seen on
professional motorola GP type radios.
The bottom section of the unit houses the speaker, the rear houses the battery
pack which is accessed by opening a clip at the rear bottom of the unit. I
know some people prefer to use alkaline's or rechargeable cells when out and
about due to the limitations of battery life when out and about, well Icom
have catered for those people by supplying a plastic spacer which you insert
in the battery compartment and then you can insert 3 alkaline's or rechargeable
batteries. A nice touch. well done Icom.

Battery compartment
The left side of the unit (As you look at it face on) has two volume buttons
one for up and one for down and a squelch button which can be used to monitor
weak signals or for monitoring duplex radio transmissions.
Left side buttons
The right side of the unit has three apertures, one for civ (Used for cloning
and computer control )this also doubles as an earphone socket a DC socket for
charging the unit and a USB port for computer control.

Right side
Display
The display is nice and big with the frequency display nice and big to boot.
However when alpha tags have been added I think you will agree that the size
of the frequency display could have been shared with the paltry size of the
characters. If you are any distance away then you will have to do some squinting
to see who you are listening to. Remember the idea of alpha tags is to see
who you are listening to so its no good being miniscule. Also 8 tags? Sorry
Icom you will have to do better than that. Yes its an improvement over the
R5's 6, but it's still not enough. Also displayed when in memory mode is an
icon displaying the status of the battery, mode in use and a 15 segment
signal strength meter. Also there is what at first seems a pointless
icon showing the volume with an up down arrow This is in fact to show that
you are in normal mode as opposed to Dual watch mode and that the use of the
rotary knob can be used to adjust the volume as well as the side buttons.

In use
Okay so it all looks good but how does it perform? To start off with once
you have charged the battery pack,(Or inserted your cells) which incidentally
is a 3.7v Li-ion job you power up the unit by pressing the orange "Power" button
and from here you can enter frequencies either via the right rotary knob on
top of the unit (The left one is for volume control) or directly using the
keypad. One thing I noticed is that you do not have to enter the frequency,
you tap in say 456.750 and it is entered into vfo you do not press 456.750 "enter" or
similar as you do on most receivers. To enter into memory mode is simply by
holding down the MR button and from there you can select a memory location
by scrolling with the rotary knob and then hold down MR until you hear the
unit beep to confirm it has been written to memory .There are a total of 26
memory banks Starting with Bank A through to bank Z. Unfortunately before you
can add a memory to a bank you have to program it to a non bank memory 0-1250
and from there you add the channel into a bank allocation so in fact all frequencies
are programmed twice into the R20, rather a waste of resources to my mind and
is just the same as the R5. One thing I must mention is there are two options
for controlling the volume. Either via the left (As you look at the receiver)
rotary knob or by two buttons on the side of the unit, one for up and one for
down. The reason there are two options for volume control is that when in Dual
watch mode the rotary knobs are used solely for memory allocation settings.
The side buttons being bigger than the R5's make for much a better feel and
do not require such a precise push. This is more apparent on the squelch button
when monitoring two sided frequency conversations. As this is where the R2/R5
struggled somewhat.
Memory banks
It appears at last that Icom have listened to us and have given us the bank
linking feature we have been asking for. In the R2/R5 you could only listen
to one or all banks whereas now you can select which banks you want to monitor.
This is useful for instance if say you are at an airshow and want to monitor
civil and military airband. If you have these programmed in different memory
banks you can select those two banks to be scanned and that way you filter
out all the other radio transmissions which are programmed into your scanner.
one thing that took me a lot of time to get used to is switching from memory
mode to vfo.and to switch from scan to memory mode, things went wrong forcing
a power off power on cycle to get the settings right but this was my fault
for not reading the manual properly. The correct procedure for any of the above
actions is to press the "Dualwatch" button this for instance if you
are in a scan will stop the scanning process and will halt on the memory channel
and if you so wish, from here you can switch to vfo mode.One more thing I should
mention is that the R20 appears to use the same memory banking system as the
R5 whereas the frequency has to be entered into a memory allocation and from
there the frequency can be duplicated into a memory bank. At first glance you
could be forgiven for thinking that it is a waste of resources using two different
memory locations,( I know I did) however this isn't the case you are not actually
duplicating it into a
bank memory. You are simply adding a bit of configuration info to the
main memory entry to tell it that this particular frequency should be
indexed to Bank X, location Y.
So, for example, you might enter a new frequency into location 347 and
then edit that entry and add in that the data in location 347 should
include an index reference to Bank D, slot 12.
So, just as you would attribute settings to memory location 347 such
as mode, step size, CTCSS tone, offset frequency etc, you also set
which bank and slot you want it to show up in.
It's a lot like writing a web page and then later adding an
image to one of the pages, the image that you see on that page isnt really
there it is in another directory on the web site.
In all 26 memory banks are provided
which should be enough for anyone. Scanning speeds are more than adequate
in fact they are pretty damn quick Icom quotes 100 ch's/sec I didn't get chance
to check this and I suspect they mean the search rate rather than the scan
rate. But it is definitely quick and an added bonus over my R5. Nice to see
there is a selectable time before scanning resumes but would have been even
better on a per channel basis.
Search banks
There are 25 search banks available (Or scan edges as Icom insists on
calling them) unfortunately I can see no way of linking these as you can with
the memory banks, which is a bit of a bummer. Icom got it right with the memory
banks but forgot the search banks. Maybe the next model will have this feature?
On air
So you now have all your favourite frequencies programmed in how does it perform?
For the purpose of this review I used two antennas firstly I tried the stock
whip telescopic antenna that is supplied with the unit this is a six segment
very long ariel and I could see this being easily broken due to a combination
of the sheer size and that it is made of the poorest quality metal. Users of
Uniden mobile/base scanners will be familiar with this as it is the same poor
quality. I then tried it with a Watson w-889 which is my benchmark aerial for
reviews as it gives the radio a fair chance as this I have found to be one
of the best all round performers and also I can judge a receiver equally and
not wondering if it performed well/poorly due to the antenna that it came supplied
with. Starting on 30 MHZ which is about the lowest I go, I found the R20 performed
superbly bringing in distant weak signals. on 70 MHz fire I found the R20 adequate
nothing outstanding and not poor. Basically I have come across better and come
across worse but it lags way behind the AOR 8200, which I found to be an excellent
performer in that part of the frequency spectrum.
Testing on my test Airband frequency of
119.250 I found the R20 outstanding very impressed with both sides of the
conversation booming in. When you realise that I regard any receiver capable
of just about picking up the control tower side of the conversation from my
location as being good, then strength six gives you an idea of how well the
R20 performed here.( Incidentally I have heard reports that the signal strength
meter is set too high. Whilst I agree they are not to be taken as gospel I
found the setting to be about right, definitely more accurate than the one
that comes with the Uniden 780). I was very impressed. Further testing brings
in Birmingham airport frequencies loud and clear that's ground and air! I think
all other scanners only manage the ground side of the conversations when at
a good vantage point in my house.
VHF am signals in the 150MHz area were also loud and clear no problems with
the am mode in fact one signal that is impossible to receive on any other scanner
I have owned due to the range was just audible on the R20.
Listening to the PMR vhf band 163-170 MHz area I found the R20 again to be
extremely good. From a good spot in my house I found signals booming in from
a neighbouring city loud and clear. I have found some receivers to be useless
on VHF pmr so this was pleasing to find the R20 was not deaf in this area.
Moving up to the 177-200 Mhz area which in the UK is used by various pmr trunking
radios I found the R20 to be once again very good indeed bringing in signals
I had not heard before on this part of the radio spectrum.
UHF Military I am not capable of giving a fair assessment as I live miles
away from any military airbase and the only frequencies monitor able are airborne
transmissions that I have no idea how far the transmission is coming from.
UHF PMR (Incidentally PMR is a term used in the UK for Public Mobile Radio
which could be the bin men or gas engineers, taxi co's etc.) The R20 again
performed very well, not outstanding I may add but definitely not badly either.
One distant frequency which is very touch and go on any receiver was audible
on the R20.
When out and about in my car using the mag mount brought in some worth while
observations. For a start the UHF band sensitivity improved slightly over
the supplied whip I have seen many referrals over the years re
extension sizes of telescoping type antennas for various frequency ranges and
to be honest for what little gains you may get for collapsing for uhf when
weighed against the losses you will get on VHF I find it best to leave fully
extended at all times. Pager signals could be heard on most of the VHF PMR
bands but not to any annoying degree and and only when very close to a pager
site. When passing right underneath a strong pager site although the signal
was nearly wiped out it managed to fight through and stay very audible. UHF
of course remained untouched and oblivious to any pager signals going on around
them.
Testing with the watson showed that this receiver is definitely no slouch
on UHF and gave results to prove it, however there was a slight trade off on
vhf showing the stock one to be better on VHF and the watson better on UHF.
CTCSS/DCS
When I first saw the features of this receiver being advertised I saw somewhere
that it would decode DTMF signals, of which I was dying to try out. Unfortunately
I think someone got confused with DTCS, which Icom refers to for what we call
DCS. Okay the R5 has ctcss/dcs features so does the R20 do it any better? Well
first of all to search for any tones in use you now just press and hold down
the T-Scan button and the R20 will search for any tones in use. So the R20
is definitely better there. As for decode speed I can't really say that it
is any quicker than the R5. After using a Radio shack pro-92 sort of spoils
it for other scanners as this decodes tones instantly. If they can do it why
can't the others? Apart from that it worked flawlessly, working out how to
store a tone took some getting used to and I'm still not sure I'm doing it
the best way but it works ( I really should study that manual) and once stored
need never be worried about it again.
Priority feature
Icom still have not listened, it's still the same useless priority feature
that comes with the R2/R5 scanners Icom get it sorted!!
Backlight
Has three settings automatic, off and on. For most of the time I kept it to
auto so every time I pressed a key or turned a knob the display and keypad
lit up. Incidentally when first looking at the R20 you could be forgiven for
thinking the keypad does not light up but in fact it does. The backlight on
the display is a very good effective green in colour light. Giving more than
ample lighting this should suffice for anybody's purpose. I would like to have
seen an automatic function where you could set the receiver on receipt of a
signal to light up momentarily. This was a feature I liked about the 8200 mk
3.
Attenuator
The attenuator I personally would not bother with it is very harsh and completely
flattens any signal apart from the very strongest ones. A better idea would
be to employ two attenuator settings like the Alinco djx 2000 that way you
could choose the severity of the attenuation. Also it appears to be another
case of all or nothing. Meaning the attenuator cannot be set on a per channel
basis. Once activated it is on for every channel so is only any good for when
sitting on one frequency.
Band scope
It has one it works and appears to work well. But regular readers of these
reviews will know I see little point in having it. I mean, you have a receiver
capable of searching the frequencies and you are able to listen but with the
band scope all you see are peaks. I'm sure someone will like it but for me
I'd rather some other feature added in its place.
Battery life
The battery life of the li-ion power pack is phenomenal. 21 hours of continuous
use before showing signs of need of a re-charge! This was with the display
light set to automatic for most of the time and on scan, manual mode etc. In
fact a normal type scanning operation where you would scan for something of
interest and hold when something interesting was heard. Battery saver was set
to the default automatic. A lot of the time the unit was on full volume when
it was in my car, now that is usually a great battery drain. Now if you were
just monitoring one frequency with display light off god only knows how long
you would get. This is amazing and users that like to spend a day out and worry
about the battery pack dying need worry no more.
Battery saver
Yes it has one (so should any self respecting scanner these days) It comes
with two settings off or auto.
Dual watch
This is not a feature I would have thought I would use much but after testing
it out on the R20 I think I will be using it a helluva lot. You can monitor
two frequencies simultaneously with this feature. So why would you want to
do that? You may ask, I know I did. well for a start you can monitor frequencies
using duplex, split frequencies where talk through is switched off. By entering
the base frequency and the mobile users frequency you will effortlessly (As
long as mobile user is in range) pick up both sides of the conversations. Not
only that but you can enter two of your chosen programmed frequencies. e.g.
the police are chasing suspects using the main channel and some units are talking
to the helicopter on another channel. All you have to do is enter both of these
conversations and you can easily monitor what is going on without missing anything.
I found the bandscope on the R20 very easy to use and an added bonus is you
can even scan the channels whilst using this feature. You can even leave one
channel on "watch" and the others scanning! Awesome! This is another of those
"How did I live without this?" features that makes this receiver
an even more great bit of kit.

Dual watch
Audio
The audio quality gave very good results with good clean audio being heard
with no distortion when on full volume. However this is definitely not the
loudest of scanners meaning that when out and about in a vehicle the volume
really does have to be cranked up to full. You may want to consider this if
you intend usint it in a noisy environment.
Recording
As if I wasn't impressed with this receiver enough it comes with this nifty
little feature. Yes you can record what you hear. By using the bottom row of
buttons which are purposely set to look like tape recorder buttons you can
record up to 4 hours of audio. What's more you can set it so that it only records
audio without all the dead spots in between. This all sounds good but is it?
Well I am pleased to say yes. It performs superbly. There are 3 recording modes.
Fine which gives crystal clear recordings, (Doubt if you can tell the difference
from the original audio) normal which gives slightly reduced audio quality
and long which gives even less quality. So why would you use it on any other
setting than fine? I hear you ask. Well the answer is simple the better the
quality the shorter the recording life is. I'm not sure of the maximum recordings
on each setting but the "Long" setting gives up to about 4 hours
of constant radio traffic recording and by 4 hours I don't mean if you set
it at 12 o clock the recording will cease at 4. I mean it will record 4 hours
of audio if you set it to record just the audio (For my purposes I can see
no reason to have it set any other way). Incidentally the long setting you
may be wondering what the quality is like. I can say it is still good and not
annoying to the ears and does its job well. After going to bed and leaving
the R20 to record the nights action (I turned the volume right down) and then
listening the next morning I wondered how I have ever coped without this function
before. Yes there is software available that will let you do this on your home
computer but you have all the hassle of connecting your receiver to the PC
and then you are tied the next day to the PC to monitor all the activity. Whereas
with the R20 you can carry it with you wherever you go. Not only that it also
does a better job of it. This will be a big selling point for the R20 I have
seen this feature once before on the Alinco DJX 2000 however the recordings
on that are very brief and the Icom does it so much better.
During this review I did not check the lower frequencies in use or the various
modes available. I am a vhf uhf man and there is much more capable equipment
dedicated to these frequencies and to be bloody honest I don't know what I
am talking about when you go down that low or at the higher extremes the R20
is capable of. So I really can't be fair to the R20 in those bands.
Final opinion
This scanner to me is a winner! No doubt about it. During this review I made
comparisons to the R2/R5 scanners as they are ones I am familiar with from
Icom. When in fact this was meant as a replacement for the R10 of which I
was not familiar with. Although I heard a lot of bad things. Not only that
but I suspect Icom are trying to gain the throne held for many years now of
what I have regarded as the top hand held scanner and that is the Aor 8200.
So how does it compare to the 8200?
I would answer the question like this. If you already own an 8200 with the
ctcss card etc. then maybe there is little point selling it to buy an R20.
However if you are tossing a coin between the two then I would say go for the
R20. Built in ctcss/dcs Remember You pay extra for ctcss with the 8200 and
no dcs capability at all. Voice recording feature (Boy I love that) Dual watch
(yes I love that too.)
What would I like to see in the future well search bank linking would be great.
Icom got it half right this time with memory bank linking. Light on when squelch
opens. This would have to be optional for battery saving reasons. CTCSS/DCS
instant decoding come on it is possible and you know we want it. Also the attenuator.
Memory selectable with two selectable settings. Audio needs cranking up! Although
it suffers from no distortion the maximum volume is on the poor side. Another
thing from what I have been told the software available for the R20 is supposed
to be very basic maybe butel will design an arc 20? Also sort that bloody priority
feature out.
The R20 has features which I have not even touched as yet such as auto power
off, Computer control VSC etc.
The R20 is a brilliant performer constantly amazing me with signals being
brought in on VHF a host of good features that a discerning scanner user will
utilise. Also a cinch to operate. The battery life is amazing and that alone
is a good selling point about 3 times longer than the 8200 and then some! The
voice recording feature has got to take the award for best feature in my opinion.
Now to send it back. Send it back? No way I am going to buy this baby!
Updates
This is a feature I will add to reviews as when used for a certain
amount of time things that were not apparent in the short time to do the
review transpire with continuous useage.
I have noticed when in a scan that on some frequencies
if when it stops on an active channel and you press the
Sql button to monitor the repeater input freq, that when you release the
button and it returns to the original frequency it appears as though conversations
have ceased, but if you flick away from the ch and back again there is
audio still. So always best to stop the scan before performing this operation.
Also the R20 suffers quite badly from nearby stations crashing in on other
frequencies e.g. My local police on 452.725 gets a neighbouring police
transmitter on 451.450 spluttering through with sometimes enough clarity
to hear whats being said. I take it this is intermodulation? I thought
this was just happening on UHF but found it happening on VHF too. One answer
is to use the attenuator but I find the setting too harsh and allows only
the very strongest signals to come through.
