[Yaesu] Fox Tango filter for FT-901/FT-980

[Fern Rivard]

    I have a crystal filter made by Fox Tango, model YF 89H 21, 
frequency 89875 khz marked on the box as correct for either the FT-901 
or FT-980 transceiver.  Bandwidth of this crystal filter is 2.1 khz. 
Asking price is $50 US plus mailing costs.
    Thanks from Fern
