2300 Hz 455 kHz SSB 10-pole Collins filter
Note: bandwidth is measured by the manufacturer at -3 dB; we measured shape factor at -60/-6 dB.
Note: Collins mechanical filters are no longer in production. **THIS FILTER IS DISCONTINUED**
Note: For the closest compatible filter for FT-817, FT-818, FT-857, FT-897 try INRAD #706 at 2.5 kHz bandwidth. Plugs directly into the 2.3 kHz SSB filter slot in these transceivers and is only slightly wider than the 2.3 was.
