Read about MH-67A8J rlectret on eham and other groups - you must cut the yellow wire inside the mike. ?Audio is good snd crisp, cuts through unlike the muffled yaesu stock dynamic mike.
They ste Chinese copies, I use on both FT817 and FT857, heaps on ebay for around ?US$20 or less.
See what others think but CUT the yellow wire. 73,
