Anthony,
I suggest you consider AFC. Not enough demand for that wide a filter.
Murata makes some 30 KHz 10.7 MHz filters for communication receivers.

Hi David,
www.Mouser.com carries quite a few of the Murata filters
including this one: CFULA455KB2A-B0
which is spec'd at +/- 15KHz @ -6dB and is US$3.92 in qty 1.
Happy New Year and 73,
Tony AA2TX
