I have for sale a Yaesu MH-48 DTMF Hand Microphone which works with the FT-7800R, FT-8800R, FT-8900R, FT-2800M, FT-1802M, FT-1900R, FT-7100, FT-2900R, FT3000M, and probably a few others. It will also work with the FT100D but all of the buttons won't operate correctly on that radio. I am asking 25ドル shipped for it and can take paypal/check/MO. 73s John AA5JG
