Icom R1500 Review
June 2007

Specs / what you get
The Icom IC-R1500 remote head / PC control DC – daylight receiver is one of four models currently available from Icom, a well known and much respected electronics manufacturer in Japan.

Many amateur radios operators swear by Icom gear and my previous experience with Icom equipment has included the R5 and R20 handheld scanners, the V82 amateur 2m handheld and IC-P7A 2/70 mini handheld as well as the monster R8500 wideband receiver.

All of my previous experiences with Icom have been very enjoyable and about the only thing I can say is that their gear is very different from your average Uniden or Radio Shack scanner and so if your use to that sort of equipment then be prepared for a fairly steep learning curve with the R1500.

The R1500 has some very impressive specs / features, some of these include:

• 10 kHz-3300MHz range
• 2600 channels per file (1000 w/R1500)
• Scan rate of 60 channels per second.
• 10, 20, 50, 100, 500Hz; 1, 2.5, 5, 6.25, 8.33, 9, 10, 12.5, 15, 20, 25, 30, 50, 100, 125, 150, 200, 500 kHz; 1MHz steps
• AM, WFM, FM, LSB, USB and CW
• CTCSS/DCS decode
• Multi-channel monitor
• Recording operation
• Band scope
• Signal meter
• Attenuator
• Narrow/wide filters
• Noise blanker (NB)
• Automatic notch filter (ANF) (optional)
• Noise Reduction (NR) (optional)
• Voice squelch control (VSC)
• Priority watch
• Auto store
• Frequency offset (duplex feature)
• 6-character alpha-tag (On remote head)
• 50 search limits
• Import / export CSV files
What you get out of the box:
Icom R 1500 unit – this is quite large but lighter then what it
looks and seems to be very well built.
It has the following connections:
BNC aerial connection
Ground Connection
12V DC in
PACKET connection
Remote controller
USB Connection
External Speaker

12 V DC power supply – this is quite small and seems to work fine.

USB Cable – this is quite short and Icom don't recommend the use of
other USB cables, I have tested it with a good quality 20M USB cable
and it still seemed to work ok. This might be a good option for somebody who wants to mount the R1500 unit away from the computer and use a shorter coax cable for less signal loss, maybe in a roof or somewhere like that.

Test aerial - This is a telescopic whip on with a base that has double
sided tape and a few meters of coax, I used it for a while and seemed
to work ok but you really need to use an external aerial to get the
most from it.

Software / driver CD – This has the drivers and the Icom software. The
software in general is good but a few of the features seem to not
quite work as they should, the scope feature seems to cause the radio
to drop it's audio and the record feature does not work at all, if
these are issues with the software or I have not got them setup right
I don't know.

Remote Head – To me this is the best thing about the radio and works
very well with it. Not all the features that you can use via the PC are supported on the remote head but there are enough to keep you busy for quite a while.

PC use
The first step to getting the R1500 working with a PC is to install the software and driver that comes on the enclosed CD, this is a simple process for anybody who has ever installed software before and only takes a couple of seconds to install.

When you connect up the R1500 to the computer (in my case a laptop) using the USB cable you are asked which port it is on, once you set this you are away and can explore the software and the many features it offer.

The R1500 software seems to work very well and has a lot of features.

I have programmed in the 360 channels I normally have in all my radios, one thing is that Icom have finally got the software right this time as far as programming goes, you can now import / export you files in CSV format so it is a simple copy / paste job, unlike the software for the R20 which you had to manually type in everything.

Each bank can have 99 channels but you can finally have multi-bank
scanning which makes it great for people like me with heaps of
channels they want to scan.

My normal test of scanning my 360 VHF / UHF channels has shown that not a single channel has had any issues at all with lockups or rubbish from my laptop getting on to the radio, if only I could say the same for my 396T which has quite a few issues when used near my laptop, especially in the UHF band between 470MHz and 490MHz.

I have also run a search of the following ranges to see if I get any
problems with lock ups, here's the results using the internal test aerial.
70MHz – 86MHz – 3
118MHz – 136MHz – 1
144MHz – 174MHz – 3
406MHz – 512MHz – 14

As you can see above it does lock up on some channels, thankfully none
of them carry traffic I want to listen to so I am not fussed about it.
The UHF channels above where it locked up were around the 408 MHz
area and the 470-490 MHz area.

One of the best features I have found is the 25 channel multi mode
monitor; basically it allows you to program 25 channels and watch on
the screen as they become active, you then simply click on the active
channel and you hear the audio, I think I am going to get a heap of
use out of this feature, I was using it last night for a while and it was really good to be able to see what channels were active and simply click on them and hear the audio.

I tried a little bit of HF using the laptop to control it but I was getting too much RFI from my laptop to make it worth listening.

Remote head use
The remote head works very well and that's how I use it most of the
time, as it has a 3.5m cord so I can leave the main body of the R1500
beside my bed and just move the head around depending on where I am

Setting up the R1500 in my car, which required the purchase of a $20 cable to power it and taking it to a hill top in Launceston really showed what a versatile receiver this is.

I setup at Free Landers lookout in Riverside. I
decided on that spot as it is line of sight to Mt Barrow, Abel's
Hill, West Launceston and the FM station in riverside so it is a
fairly tough spot for radios, my 396T performs worse up there then
even on the top of Mt Barrow with all the high power stuff a only
few hundred meters away.

Running my first test of scanning my 360 VHF / UHF channels I have
programmed in to the R1500 with the mobile aerial didn't show any where
near as many problems as I was expecting or what the 396T has up
there with even it's normal aerial let along on the external one. I
only found 4 channels with problems and they were not any ones I
really listen to that much.

Searching each of the following bands with the mobile aerial showed
the following:
70-86MHz – 5 channels with broadcast band audio / lock ups.
118-136MHz – 0 problems (VERY surprising)
144—174MHz – 4 channels with mainly 7NT (91.7MHz) audio
406-450MHz – 12 channels, mostly between 411-414 with TV audio.
462-512MHz – 14 channels with TV audio, around 488MHz, 497MHz and
865-870MHz – 9 EDACS control channels and 6 channels with broadcast
audio between 867.8 and 868.5625MHz

So overall it seems to work quite well and I am very happy with it.
I also had a bit of a listen to HF with about 20m of wire hanging
between my car and a tree up there and it seemed to work ok, I did
notice some broadcast band signals between 2MHz and 30Mhz but I
guess given where I was that is not really unexpected.

I have been using it at home this afternoon and running it side by
side with the 396T scanning the same VHF / UHF channels (no
trunking) shows it's scan speed is around 40 channels a second and
that I am picking up so much more then the 396T does.

Good points
- Remote head is great and works really well.
- Wide Band coverage
- Fast scan / search speed (around 40-50 steps / channels per second)
- Bank linking actually works
- AFC (see how far off people radios are on UHF CB)
- Voice Scan – Gets rid of the annoying EDACS beeps and is set per channel
- 50 search banks
- Many other things I have not even tried yet.
- Great Audio.
- Multi-channel monitor (see 25 channels at once)

Bad points
- Has some small issues with broadcast audio (AM and FM bands) on other channels.
- Only 6 character alpha tags on remote head.
- Manually adding a channel on the remote head is easy once you have done it a few time but is very slow

Overall comments
This radio was purchased as my do it all radio and has to last me a few years so I was looking for the best radio that I could afford, I think I have found it.

One strange thing I have noticed is that you have two totally
different sets of memory, one when you are using a pc / laptop to
control it and another when using the remote head, when using the
different control methods you can only access the memory for that
mode, this means you have to keep two different memory sets updated
with information if you want to change info or add new stuff.
When you connect up the USB cable you can read / write the "internal"
memory that is used with the remote head and make changes but you
can't scan the channels, only the ones in the pc / laptop file.

So over all I am quite happy with it. Icom seem to have taken the best
features of the r8500 and the R20 and put them all together in to this
The software works very well and I can't find anything I don't like
about it so far, it is full of options and it will take me quite a while to come to terms with it all.

Sure it is not quite to the same level as an AOR 5000 type radio (but it is close) and some people might not like the idea of having a radio that needs a pc to use some of the features but to do most things you can use the remote head.
I really do think that I have finally found a radio that suits my needs. The VHF /UHF performance is great for my needs and is better then my Uniden 396T.

I have not had much of a chance to use HF on it yet but having a bit
of a listen to some HF channels this morning has shown it is capable
of picking them up fairly well, 8867KHz and 5643KHz are two I have been getting very well.

Over all I am very impressed with it and it will be my main rig for quite a long time, atleast until the R3000 comes out 

A nice little review; I'd encourage you to make a Wiki article out of it.

Re your comments on laptops and RFI; one of the biggest offenders is the cheap power supplies, which usually have no shielding or filtering at all. Sometimes changing them out cures much of the problem. I'd recommend one or two, but being in Tasmania, it would be difficult to know if you have any computer stores in your area.

And Icom misses the US market yet again. Where is the 7.5 kHz step?

Also still waiting for reliable (and built-in would be nice) P25 digital capability. NAC decoding would be nice, too.

If my rather poor math serves me, you could potentially tune a signal on a 7.5 khz allocation with a 2.5 khz step. Kinda slow, granted, but it would work.

Personally speaking I'm waiting for Icom to apply the lessons learned with their R75 to a PC based receiver. The HF performance, as discussed in a recent QST article and elsewhere is OK but not nearly what it could have been; the selectivity options are pedestrian at best. This is one area where the RX320 shines, and it shouldn't really be that hard in DSP to synthesize better filters.

I can't comment directly on the 1500, but the 2500 when run via PC software has a user defined step, so 7.5 KHz can be implemented. Sadly this does not translate to the remote head, which offers the static list of steps. I e-mailed Icom asking if future firmware upgrades might be able to build the 7.5 KHz step into the remote head. I'm not holding my breath by any stretch, but hopefully someday it'll happen.
