I did two things to improve the connection between the speakermic plug and the jack on the FT-60. One was to ensure that the plug that goes into the speakermic jack has a very skinny body, so that the plug shell doesn't get hung up on the too small hole in the housing body of the radio that surrounds the jack opening. Conventional 3.5mm TRRS jacks often get hung up on the body and can't be fully seated into the jack. And they didn't even get it right on the next product. For example, the specified Yaesu cloning cable for the FT-70 has a body shell that is too fat to fit into the FT-70 speaker/mic jack; it's not even close. Yes, that's an FT-70 problem rather than an FT-60 problem, but it's an example of a problem not being corrected on the next design cycle. Second was to remove the black grommet from the FT-60 speakermic jack opening so that the plug can be fully seated all the way into the jack. If one looks carefully you will see that the grommet keeps the plug from being fully (and correctly) seated into the jack. There's no grommet on the adjacent power jack so why have one on the speakermic jack? Once I removed the grommet from all four (yes four!) of my FT-60 speakermic jacks and used short extension cables with skinny plugs, my speakmic problems all went away. Very reliable operation now. There's a lot I love about the FT-60; it's my favorite HT of all time. But how this speakermic plug/jack problem was allowed to get through the internal design review process is hard to understand.
