YAESU FT-70 headset connector wiring

[kwhunter]

Hello.
I wonder if somebody knows how the 4 position 3.5mm connector for the headset is wired? I have an aviation headset I want to use with the handheld and short of buying a Yaesu headset and checking the wiring I have found no other information.
Thank you.

Hello,

I did a little googling and found this.

The official adaptor from Yaesu is a CT-44. It's used across a wide range of Yaesu HT's. Link above will download a word document that has details of the wiring for a FT-60. It should work for your FT-70

Hi.
Thank you so much! I might have used the wrong search criteria as I didn't find that doc.

You're welcome.
I searched for CT-44 schematic, as I figured someone would have worked out how the adaptor was wired.
