My new Icom IC-E2820 uses an OPC-1529R cable for data communication (among other things) this same cable is also used by the IC-91, IC-2200, IC-V82, IC-U82 and probably others as well (ID-E880, see the bottom of the page). Here is how to make one (IC-2200, IC-V82 & IC-U82 users will find a connection diagram in their manual) and save around £20.
Assemble as shown below. Use the shield of the cable for the com ground connection and don't forget to put the cover of the jack plug on the cable before soldering!
Assemble the shroud over the DB9F for the finished article.
As noted by Andy (bottom) the addition of an RF choke may be a good idea, especially if using the lead for data while transmitting. Use one of the "split" types (pictured right) mounted close to the radio end, wind a turn of the lead around the choke and clip it shut.
I had a "not very nice" email from somebody (an MM3 licence holder, who will remain nameless) to say that this lead does not work, he wasted time and money on the "bits" to make it and making it. He also said that he had to buy the proper Icom lead in the end, which worked perfectly.
In reply I have told him:
I have made several of these leads, including one where I included the OPC-1529R wiring along with speaker audio and the normal control head wiring in one cable (I have had DSTAR Comms contacts and programmed the raidio memories from a PC laptop, proving that it works). Also Dave, 2W0RUH, Steve, GW6CUR and Wayne, GW1UDK (just 3 that I know of) use leads that were made to this scheme, so if the one you make doesn't work check that:
Further to the above I have received other messages:
Your OPC-1529R cable works like a dream. I did have a problem initially but that was down to my poor construction technique. When I went back into it and tidied up my soldering etc it works VERY well and is operating my 91AD as I write.
I would urge others having a problem to review their work quality as I did.
Thanks and cheers
I found and made the OPC-1529R cable using the instructions you made. It works great! 73!
Lasse Haugen emailed me from Norway:
Hi, just wanted to tell you that the description for OPC-1529R works fine on my new Icom ID-E880 with the Cloning software Icom provide at their WEB site
Thanks. LA5PPA / Lasse.

Just wanted to let you know that your design for a homebrew OPC-1529R ICOM cable works like a dream with my new ID-880H!
You might want to let your visitors know that
a) It can also be used with a USB to Serial adapter (as I am) if you don't have a serial port
b) That latest version of the ICOM software (currently rev 1.10) is a must. (Go to help/about and check 'Revision 1.1' to be sure). I found rev 1.0 didn't work with the radio I have.
c) The addition of an RF choke to the lead.
Thanks again. Keep up the good work!
Thanks Peter, Brian, Lasse and Andy, glad to be of assistance and good to know that it's still getting world wide "thumbs up".
