Repeater-Builder is looking for information on the various models of current and older Icom commercial mobiles as to their usefulness as remote bases or point-to-point links. Also we are interested in the commercial mobiles, the amateur and commercial repeaters with emphasis on:
  • What the differences are between the various models
  • The frequency ranges and which ones are crystal or synthesized
  • What makes one particular model better over another (i.e. which ones are the turkeys)
  • What it takes to move them onto amateur radio frequencies
  • If they aren't crystal controlled, information on how to program them (i.e. hardware programmer, PC program or front panel programming) would be appreciated, as well as what PC software do you need (and how to get it)

Interfacing the IC-RP1520 Repeater to a Computer Automation Technology Inc. Controller  105 kB PDF file
While the title specifies the IC-RP1520 the information is frequency independent and should be applicable to any Icom repeater that has the 8-pin DIN female accessory connector on the rear panel. And the interfacing of the the Scom and the Arcom controllers is very similar to the CAT controller family.

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/ y ahoo /dot/ com for the details of that but remember: you won't need the full version to make up this board.

Manuals and Brochures

The IC-F series, IC-U series, and IC-V series radios are commercial Land Mobile Radios (LMR).
The M-series are marine radios, the A-series are aircraft (AM modulation), the FR and UR-series are LMR repeaters and options.

IC-706 Service Manual   4.4 MB PDF file
Includes options UT-102 and AT-180. This is the HF radio that also does 6 meters. 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! And 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 remotely. There is a workaround for this that the NHRC-10 controllers have as a built-in feature: pre-program 32 memory channels with the 32 CTCSS encode tones, then to change frequency recall the appropriate tone-coded memory to the dial, then program the dial with your desired target frequency.

Data sheet on the rechargeable battery packs for the IC-2/3/4 and IC-02/03/04 series handhelds   64 kB PDF file
This data sheet covers the "amateur grade" BP-2, BP-3, BP-4, BP-5, BP-5A, BP-7, BP-8 and BP-70. Except for the BP-4 they are recharged in the BC-35 charger mentioned above (the BP-4 is a holder for ten AA penlight cells).
Data sheet on the rechargeable battery packs for the IC-H16, IC-U16   125 kB PDF file
This data sheet covers the "commercial grade" CM-5, CM-7, CM-8, CM-12, CM-96 series. The trailing B (as in CM-7B) indicates black plastic, a trailing G (as in CM-7G) indicated gray. No trailing letter (as in CM-7) indicated dark gray. All except the CM-12 series are recharged in the BC-35 charger mentioned above (the CM-12 is a holder for ten AA penlight cells).
CM-7 battery pack schematic   (also applicable to the BP-7)
This is the high power ("12 volt") pack that has an interesting design - since the BC-35 is effectively an 11v charger designed to charge 9.6v batteries this battery pack uses an internal relay to switch two 6v cell groups in parallel for charging and in series (12v) for operation.

A local group asked me to research how to use one of these as a plain analog repeater with an external controller.
This manual is useless for interfacing this repeater to an external controller...
IC-RP2010V VHF Repeater Service Manual   33.5 MB PDF file
Again, no mention of an external controller... and it's 144-148 MHz only. The local Civil Air Patrol group WAS interested in this unit for a few hours...
ID-RP2010V / ID-RP4010V / ID-RP1200VD Settings Guide   3.1 MB PDF file
Apparently this unit is designed for use as a singe D-Star repeater or as a member of a D-Star cluster. I'd like to find out I was wrong.
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.

LMR Repeaters

The FR3000 (VHF) / FR4000 (UHF) are the first generation factory repeaters.
The FR5000 (VHF) / FR6000 (UHF) are the second generation.
The FR5300 (VHF) / FR6300 (UHF) are the third generation.

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

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 label to all of his units...

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 FR6300 accessory connector pinout is identical except that pin 20 does nothing - which is a real problem as that pin is used for TX external data (like paging data) or as a flat audio input.
You are NOT going to be able to use a FR5300 or FR6300 as a MMDVM transmitter.

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 between repeater modules.
There was an third package (now discontinued) - the "CY" package that held one module, a power supply and a flat pack duplexer. That housing had a fan, and there was a "CY mod" data sheet that documented the process to add a twisted pair fan harness to the UR module. This connected the fan to the antenna relay connections inside the module.
