[amsat-bb] FM receiver filters

[G0MRF@aol.com]

Hi all.
 
I'm trying to find some 455kHz filters suitable for FM +/- some  doppler.  
Ideally, 30kHz wide and fairly small
 
I have some by Murata. Types  BLFYM-455C and BLFCM-455C but these  are +/- 
12.5k.
 
Any ideas?  I've checked Digikey, but they only seem to list narrow  band FM 
or AM filters.
Is there a Murata or Toko distributor that I've missed?
 
Thanks
