I have a Yaesu FT-101zd. My manuals are located quite a distance off. I'd like to provide keying for a Kenwood TL-922A. Where do I come off the FT-101zd for this purpose? If anyone can provide me the output, please do so. I am thinking it might be on the multi-pronged plug on the back. If you know the pinouts, it will certainly be a help to me.
