This is a heterodyne oscillator crystal for expanded 11 meter coverage for the Yaesu FT-101 /B/E/EE/EX/F series of HF transceivers. Crystal frequency is 32.520 MHz which will cover from 26.500 to 27.000 MHz. Would replace an existing 10 meter crystal. Thanks for looking! Please note this crystal will not work with the later FT-101Z series of radios. Free shipping in the ConUS.
