FAKE ICOM RADIOS

Icom Japan has a fake radio problem. (off-site pointer opens in a new browser tab)

ALL Icom radios are produced in Japan. If you find an Icom radio labeled "Made in (any other country)" they are 100% fake (note that some legitimate accessories are not made in Japan).   There are chinese and other manufacturers that are producing counterfit copies of Icom radios.   If you suspect that you have been offered, or you purchased counterfeit Icom products, please contact Icom directly: export //at// icom //dot// co //dot// jp   More details are available at the above linked page.

Programming Cables

A lot of the Icom literature refers to the radio programming software as "cloning" software. Icom has a number of different programming cables and the official part numbers all start with an "OPC-" or "OPC-i" prefix. Some sellers market them without the hyphen, the "i" or both. And some manufacturers used OPC programming cables rather than producing their own. Years ago the author of this page had a Radio Shack scanner that arrived with a OPC-478 cable in the box. The radio shop that your author helps out at one or two days a week has a number of Icom factory cables that are serial port (DE-9 based) and a couple of factory USB cables but the shop tends to use aftermarket FTDI USB cables due to past USB driver issues. Icom ships a USB driver CD with every factory cable and the shop has had driver clashes between the Windows drivers and the Icom drivers, and sometimes between two different Icom drivers. The OPC-478UC has a 3.5 mm (1/8 inch) TRS (Tip-Ring-Shank) "stereo" plug on the radio end. Some of the radios I've programmed with it are the IC-2720 and the W32A handheld. The original OPC-478 had a 9-pin serial connector on the computer end. The version Icom sells today is a USB-A to USB-mini cable and a dongle that has a USB-mini socket, some electronics, and a 1/8 inch TRS plug on a pigtail. The OPC-i966 connects to a 9-pin acccessory connector on the side of a handheld radio. One radio that uses this cable is the IC-F3161 / IC-F4161 series. The OPC-i1862 and OPC-2338 connect to a 14-pin acccessory connector on the side of a handheld radio. At one point the OPC-1862 number was discontinued and replaced by the OPC-2338, they are essentially the same. One radio that uses this cable is the IC-F52d / IC-F62d and the IC-F3400 / IC-F4400 series. The ICOM OPC-1122 and the OPC-2344 Programming Cables are the standard mobile programming cable that has an RJ-45 plug on the radio end. I am not aware of any vendor that offers a 9-pin serial version of this cable. The USB version that Icom sells is in two pieces: a USB-A to USB-mini cable and a dongle that has a USB-mini socket, some electronics, and a RJ-45 plug on the radio end. The OPC-1122 / OPC-2344 aftermarket USB cable has the conventional format: a USB-A plug on one end and an RJ-45 plug on the other. The ICOM OPC-2363 Programming Cable is a USB to mobile cable that has a round 10-pin connector on the radio end (that's an Icom specification sheet photo, anybody have a better or closeup photo of the radio end?) At the time of this writing it is used with the F5400, F6400, F7510, F7520 and F7540 series commercial radios but may be used on other product lines in the future. Your page maintainer (and the shop that he helps out at part-time) purchases all of the programming cables from Mark Dunkle at www.bluemax49ers.com. (Off-site pointer - opens in a new browser tab) He learned from the experiences mentioned above at the shop. While he prefers the 9-pin serial cables there are some Icom cables that are not available from anyone with a 9-pin serial connector. For those radios he uses Mark's FTDI based USB cables because they just plain work and work with the stock Windows drivers… You can buy directly through his web page and avoid the eBay or Amazon markup. No, Mark is NOT paying for the pointers on this web page. I doubt that he even knows of this Icom cable writeup. If anyone would like to donate additional programming cable information (such as OPC numbers and the radios that they program) please contact the page maintainer.

Some Thoughts on Radio Programming Computers and Laptops   by Mike Morris WA6ILQ This article is an opinion piece…   What works for him may or may not work for you…   His needs may align with your needs or may not.   This article describes what the author uses and why… If you do a lot of field or bench radio or repeater controller programming you might want to consider dedicating a computer (especially a laptop) to radio programming. The author prefers the Panasonic CF‑30 / CF‑31 series Toughbooks for all of his field and bench radio programming because they are Mil-Spec rugged, configurable, parts are available, they are easily repairable with mimimal tools and have a 9-pin hardware COM port that always works. The CF‑30 runs 32-bit Win7 and the CF‑31 runs 64-bit Win10. Plus he can boot either Toughbook into MS-DOS with a thumb / flash drive for the older radios that use MS-DOS based programming software. The used Toughbooks are also a helluva deal - he has two rugged laptops that were each over $4000 new in his hands and fully operational with max RAM and a new hard drive for under $300 each. The aftermarket 9-pin serial OPC-478 cable that he uses is still sold, less expensive and can be found here.   Most people will probably find the FTDI USB version to be more useful and that is here  (both are off-site pointers and both open in a new browser tab)

	Some modification info for the IC-37 family.   Collected by Mike Morris WA6ILQ The IC-37 is the 220 MHz radio. Some of the info will apply to the IC-27 (2m) and IC-47 (440 MHz) versions.
	The IC-38 is a wonderful 220 MHz monoband radio and has a very hot receiver. It does, however, have a firmware bug – it will not transmit a CTCSS tone on simplex. There is a work-around that resolves the problem: Create a new memory entry for your simplex channel but program it in repeat mode with the correct tone but with the repeat offset set to zero. You will have your simplex frequency with tone.

Additional info on the ACC FC-900 interface for the IC-900/901 can be found on the ACC Index page.
	OPC-478 Programming cable CAD files (ZIP)   Supplied By James Craswell WØVNE These files are the CAD files for a program cable used with ICOM products such as the IC-F4S series of UHF Radios. It also works with a wide variety of other radios. You need to download the CIRCAD program from http://www.circad.net/. The free demo version should allow you to print out the schematic and even print out a template to make a PCB. Or you can hand wire a board using Vector board. This is a clone of the OPC-478 cable. Hams who like Circad can get the full version, which allows you to make GERBER files to mass produce PCBS for $250 (1/4 the price of the retail version). You can email me at w0vne // at // yahoo // dot // com for the details of that but remember: you won't need the full version to make up this board.

When coupled to a high-end repeater controller that understands what a HF remote base is (like an NHRC-10, an Arcom RC210 or similar capability controller) this makes a dandy HF remote base. Just watch the pre-emphasis and de-emphasis! Note that the Icom command language in the 706 microprocessor has a firmware bug: The 706 series will not let you set the VHF / UHF CTCSS encoder frequency from the serial port. There is a workaround for this that the NHRC-10 repeater / remote base controllers have as a built-in feature: you pre-program 32 (or whatever number you need) memory channels with the some dummy frequency (like 29.600, 52.525 or 146.520) and with the 32 (or whatever) CTCSS tones. Then to set the target frequency frequency just recall the appropriate tone-coded memory to the VFO dial (which sets the frequency and the tone), then change the dummy frequency to what you actually want to use.

	ID-RP2010V / ID-RP4010V / ID-RP1200VD Multiple Repeaters Addendum   5.8 MB PDF file Looks like doing anything but D-Star or in-cabinet analog / conventional repeat can't be done.

You will see a x100 or a x200 model mentioned in some manuals. Both were an export version of the x000 module.
Example: FR6100 or FR6200.

The repeaters are programmed with Icom's standard 8-pin RJ-45 cable, their model OPC-1122U (old, discontinued in October 2022) or the OPC-2344 (current). Both will work, both were a two-piece cable, USB-A to USB-mini and a short cable that contained a ciruit board in a pod with a female USB-mini connector in the pod and a short RJ-45 male cable (see the photos). Both the old and the new official Icom cables are expensive and need Icom's USB drivers. Save a few dollars, get a FTDI USB OPC-1122 cable from Mark Dunkle KJ6ZWL at BlueMax49ers (off-site pointer, opens in a new browser tab). His cables just plain work and use the stock Windows drivers.

The FR5000 / 6000 units have an option slot in the back and one of the options is the UC-FR-5000 digital trunking module for the Icom IDAS system (their flavor of NXDN). That module has three RJ-45 jacks on the back - two for the trunking buss (the jacks are paralleled) and a third for an ethernet connection. The jacks are not labeled, the ethernet jack is the one towards the center of the module.
An IT tech at a customer site plugged an ethernet cable into the front panel microphone jack instead into the rear ethernet jack. The ethernet jack is protected from the 48 volts of Power-Over-Ethernet. The microphone jack is not!! Both the RF board and the control board were thoroughly toasted and the repeater was beyond economical repair. The customer had to buy a new repeater module and added a caution label to all of his repeaters…

The FR5000 / 6000 units are "full duty cycle" at from 1 to 25 watts output and will do 45 watts intermittent duty. They offer both analog wide (20/25 KHz / 16K0F3E) and narrow (12.5 KHz / 11K0F3E) FM modes AND also support and include the NXDN Digital (6.25 KHz / 8K10F1D and E and 4K00F1D and 4K00F3E) format right out of box. These repeaters also support "mixed-mode" operation.

The third generation FRx300 models are very similar to the FRx000 models however with two major differences:
1) The FR5300 and FR-6300 units have a GPS Disciplined Oscillator internally that locks the units absolutely on channel. There is female SMA on the back for a GPS antenna.
2) The designers screwed up. The FR5300-FR6300 accessory connector pinout is identical to the FR5000-FR-6000 except that pin 20 now does nothing - which is a real problem as that pin was/is used for TX external data (like paging data) or as a flat audio input.
You can use a FR5000 or FR5000 as an MMDVM transmitter, however you are NOT going to be able to use a FR5300 or FR6300 for that.

The FR5x00 / 6x00 units are available in two packages: the IC-FR-5000 / 5300 / 6000 / 6300 rack mount package which comes with one radio module and an open slot for a UR-5000 / 5300 / 6000 / 6300 "channel expansion module" (a second repeater module). If the customer did not need a need a second repeater module then a power supply or a flat pack duplexer (or both) could be mounted in the space. The front panel on the rack mount package has a local speaker and there are two cables that plug into the microphone jack on each of the two modules… you could have two VHF modules, two UHF modules or one of each. A short tap on the blue power button switches the front panel between repeater modules.

There is an uncommon third package - the "CY" package that held one module, a power supply and a flat pack duplexer. I've seen the CY-5000 and CY-6000 in the field. The FR package was 2 Rack Units (RU) where the CY is 3 RU high and could hide a variety of add-ons, like a preselector, a preamp, or both. The CY housing also had a rear fan, and Icom provided a "CY mod" data sheet that documented the process to add a twisted pair fan harness to provide fan power from the UR module antenna relay connections (fan was on/off with PTT) or to direct DC power (fan on 24x7). The CY housing did not have a fan filter from the factory, that could be added in the field.

	The FR5000 / 5300 covers 136-174 MHz in one frequency range. The UHF FR6000 / 6300 are made in multiple ranges. The range information appears on one of the screens of the programming software, and is encoded as the last digit of the FCC ID number – it will be a 1 for low range and a 2 for high range. The first two digits of the serial number also has that information: FR6000: 400-470 MHz: 01, 14, 41, 63 450-512 MHz: 11, 19, 51, 67 FR6300: 350-440 MHz: 22 or 62 400-470 MHz: 11, 12, 13, 17, 18, 51, 52, 53, 57 or 58 450-512 MHz: 31 or 71 450-520 MHz: 32, 34, 72 or 74
