[Yaesu] anyone sweep a Murata K12 filter?

[Clark Savage Turner]

Just curious if anyone has ever swept the Murata CFJ455 K12 filter.  It 
is the stock filter in the Kenwood 850, 940 (some 930's and some 
830's).  I think it came stock in some FT 1000's (as well as the K13?) 
and perhaps others.

I wanted to compare it to the K14 filter, the stock filter in the TS 440 
and the FT-897.  It is the same size and plug compatible, the K12 has a 
little more bandwidth and was said by Rich Measures (some time ago) to 
have much better skirts.  Is it true?
