For Sale: MURATA CFJ455K-14 2.4Khz CERAMIC SSB FILTER

 

This 2.4 KHz SSB filter has been tested in my FT817.

The mounting PCB is a bit short so I just added an external connector. See the pic for details.

If you wish, you can order the exact mounting PCB for the FT817 by contacting Arthur, SP6AB. This filter also is used in some Kenwood radios.

Price: $25 US plus shipping from Ottawa, Canada

Isn't that the stock filter that comes inside the FT 817 and 818?? The K5 version has steeper skirts and comes stock in the TS 830 and the Icom 703 and 706 as I recall. I've had a few, they all had that filter.? It is a ceramic filter, not mechanical, and the skirts are not nearly as sharp as a mechanical filter.?

In my 817, I've replaced the K14 stock filter with a K12 (Murata CFJ-455-K12 is the nomenclature, I believe) and it has steeper skirts and a slightly wider bandwidth than the K14 and I like the difference.? A bit more selectivity AND a bit more sound.
