W4RT Electronics One-Board Filter Product Reviews

The bandwidth of the 7-pole CW filter is 500 Hz and the 10-pole SSB filter is 2.3 kHz. The OBF fits into the space where the Optional Filter is normally located except that the OBF requires all of the space in this optional filter area. The OBF SSB filter functionally replaces the Yaesu-stock 2.2 kHz MuRata ceramic filter contained in the FT-817.
