Correction: I should have looked at "Resonators" instead of "Filters"
10MHz ceramic resonators are readily available and have Q factors in
the range of 900 to 4000 which results in a BW between 11kHz and 2.5kHz.

the prosperity and technological sophistication in the world is of no
use without that foundation.
