[Elecraft] 200Hz vs 250 Hz filter

[Ed Muns]

BTW, all this discussion about what each filter's bandwidth actually is vs.
what it's name is, raises a related point.  With the K3, the DSP bandwidth
at which a given crystal filter kicks in can be set to the nearest 50Hz.
For example, if your "500 Hz" filter actually measures 565Hz at the -6dB
point, then you can tell the K3 it is 550Hz wide.  Same for the center
frequency.  If yours is off by a few Hz, that can be cranked into the Fc
parameter for the filter.
