Yaesu: Can anybody help me wire my cable for FT-891

[paulears]

I rather thought you'd have tried that first, to be honest. You said you'd googled every combination in your first post. We kind of assumed you'd read the manual and it wasn't in there.

I read the stock manual. Just found the advanced manual. Actually didn't realize it existed before.

 

[paulears]

Got you!

 

[KF0AWL]

Got you!

I think my problem was I was i was so focused on wiring schematics during my search I didn't even notice some things that might have helped.
But I think with the help of everyone I have pieced this hint that hint together and might finally be there!

Most commonly called a TRRS, or Tip Ring Ring Sleeve.

My bad. It was late.

 

[KF0AWL]

Thank you everyone that added info here. I have it wired up and after supper ill come back and let you know how it worked!

We've all been there...

Well guys, after many frustrating hours and late evenings.
I'm not to big to admit when I have been bested... I gave up and ordered a NORMAL computer and audio splitter tonight. This is one time my build it myself just couldn't get it done.
Thanks for trying to help 🙁

 

[ArloG]

Works like a peach for me.

I wonder if maybe the issue is your computer? Have you actually checked it can send and listen at the same time to the headset port? What software are you using? Can this access the headset port? I've never managed to get this MacBook to allow input and output at the same time?

Which model did you order? What is a "computer and audio splitter"? If you ordered something like ArloG suggested, that's really an external sound card with USB interface - an excellent choice. That won't rely on the laptop's internal sound card.

Were you able to try your original DIY cable on a computer that had separate input / output to confirm your theory is sound? What is the pin-out for your DIY cable? What schematic did you follow?

If you did, now you need to make sure that changing formats to the TRRS works. You need to find out the pinout for the laptop TRRS. There's a good chance it's the CTIA standard, but that's not set in stone. I highly suggest buying a cable and connecting wires - soldering a TRRS plug is very hard to do. This can be done by cutting the TRS plugs of your DIY cable, or rig up a patch cable with one TRRS plug and two TRS sockets. Easy enough.

I gave up the whole idea mostly because the headphone plug i was using was crap to solder to. Plus a guy mentioned the Lenovo issue and the company admitted it on top of the fact I looked up the wire scheme and it is goofy.
So with all things considered I'm just going to take my din plug and wire that to a in and out duel pigtail and plug those into the 2 into one on a normal computer

Went with a Dell chrome book, the splitter will be I wire my Din cable into a duel pig tail of one for audio in one audio out that will plug into a 2 into 1 input 4 pole splitter made for (NORMAL for 99% of computers).
Most laptops these days have a single input output 4 pole plug so i didn't have anything in the house old enuf to accommodate testing the first DIY. THE schematic is from my hours of research online line of how to build this.

I have the din plug schematic from my my research, and just rebuild my original cable test it and see how it works.
Believe me when I say I learned a LOT from this adventure even if it didn't work as I hoped.
IF all goes well this time, then I'll pick up a external sound card to plug in.

Recording and pro audio people like me have a few unwritten rules about audio on computers and in general, it’s quite simple. PCs are universally awful with their audio. We gets hums, buzzes, noises, poor tolerance on the physical location of the two rings on a connector, the inability of four conductors to do two ins and two outs, and the dreadful audio quality. We are so used to odd noises superimposed on the audio, leakage between in and out and latency. Our solution is an external interface with decent connectors. The stories I hear of people doing radio things makes me wonder if audio problems are causing the radio people’s frustration. A thousand pound computer has ten pounds worth of audio quality if you are lucky.

It looks like what you need to build is at 3:01, but if he didn't show it tested, I'd think it wouldn't work. The image below infers most PCs use the ring 2 as ground - his ground uses the sleeve. It's possible his USB adapter uses the OMTP standard.




That said - the video

Like I mentioned. Measure voltage between ground and mic. You will probably find there is because pc and phone mic's use a condenser mic versus a dynamic, or moving coil, microphone.
And I 100% agree with paulears.
