[ARC5] Crystal Filters in BC-455

[Fuqua, Bill L]

  I have been working on a homebrew receiver for the ARRL Frequency Measurement Test.
There are two receivers, one has crystal filters for 4 WWV frequencies. The other is the 
test signal receiver 
Anyway, I have used 2.5 MHz crystals from mouser to make a filter with less than 100 Hz bandwidth. Naturally that
can be widened by lowering the Q. 
  It occurred to me that 2.5 MHz is not far from the IF frequency of the BC-455. In fact
Digikey has a 2.949 MHz crystal which is even closer to the 2.830 MHz IF. Naturally the Local oscillator
would have to be aligned but being only 4% shift in IF it should still track and match dial fairly good.
  I remember some earlier discussions about using crystals in ARC5 receiver IF's but don't recall the 
outcome.
