Just acquired a used FT-890 fron an estate.

Without opening the radio, is there a way to tell if any of the optional filters are installed?

Thanks,

John

If it's the same as the FT-900, and very likely it is, then you can check for the CW narrow filter by pressing the CW mode button that toggles the filter in and out. You will hear a clear difference when the filter kicks in. The SSB filter is more difficult to identify because once installed it is always active and my own experience is that I could not hear the difference between the delivered ceramic and the Collins or Yaesu SSB filters.
