Hello,
Radio ID-52
Using the Icom OPC2144 ( Slim L-Type plug adapter cable for speaker-mic & headphone)
Can I use (Yaesu FT-65R Cable for Digirig Mobile – digirig) Yaesu FT-65R Cable for Digirig Mobile Cable along with the Icom OPC2144 adapter to my Digirig?
I am unable to find pinout information for the Icom and I am unsure if the pinout is the same between the two.

From what I understand the OPC-2144 adapter breaks out the connectors for regular stereo headphones and mic.
Here’s the pinout for Yaesu FT-65R cable:
If 3.5mm side of OPC-2144 is for headphones, 2.5mm side is for mic and if the spacing matches (7.5mm) then it might work.
Thank you for the assistance. I will measure the connector spacing and report back. I recently ordered the Yaesu HT cable from the Digirig website.

Spacing on the OPC-2144 adapter appears to be 10mm.
Count on me for the ID-52 cable too.
I am trying to get one of those cheap handmic and give this it a try.
I tried to use separate 2.5mm and 3.5mm to connect to the jacks. Unfortunately mine were not narrow enough to reach the jack.
I also could not find a cheap hand mic to buy and salvage the cable.
A baofeng cable DOES NOT have the right pitch or at least the one I got has a slightly bigger space between plugs.
While building the prototype cable I salvaged the cord from this fella:
Build info can be found here:
I was about to buy one but remembered that I tried this before, these dont go all the way in the ID-52 sp/mic jack.
Looking at speaker/mics specifically claiming ID-52 compatibility (HM-186LS), it appears that they have a wider notch with some o-ring for waterproofing:
These are pretty spendy, so I’d still go with the cheap one and give the molding a boxcutter treatment if it doesn’t cooperate.
I managed to make the cable, it works fine with the ID-52. Tested with Soundmodem. I used 4.9K resistor.
Did you use cable with waterproof connector or a cheaper one?
Did you have to modify the molding?
I used two separate 2.5 and 3.5 plugs, yes I had to cut/trip both, if it helps you I can do some measurements tonight.
Yes, somebody else following the same process will find this useful.
Here is my homemade test cable for ID-52 HT. I did not want to destroy my ICOM OPC-2144 adaptor so I ordered pigtails and a TRRS with a breakout. Works great! Now I will solder things together and clean it up.

Thanks for sharing, Chris. Looking forward to seeing the final build.
Testing a similar cable with Audio & CI-V.
For the ID-31Plus.

Good post!
Does the CAT control work well? What are your experiences with it?

Still testing, but it seems to work. 
【CI-V】無線の遠隔操作 【ID-31/ID-51/IC-R6】 - YouTube shows it working.
DIGIRIG and Ham Radio Deluxe works.
Need to test WSJT-X, VARA-fm, and Winlink.
A modified hand speaker/mic/digirig combo with PPT & PTL(push to listen) be nice to have for testing. Allowing for directed nets and monitoring signals received. Or just A/B switcher SPEAKER MIC / DIGIRIG might work.
Off topic: Does anyone monitor their DIGIRIG audio on the PC speakers?
