[Elecraft] Need to shift 8 pole 2.1 filter?

[Don Wilhelm]

  That is only because TRX-manager does not "do the math" to shift the 
filter center frequency.
It can easily be calculated from the current width and filter center 
like what is done automatically for you inside the K3 when you turn the 
Hi-cut knob.  Yes, it is not provided as a separate command in the K3 
programmers reference, but it is easy to do - move the center frequency 
down (shift) by 1/2 of the frequency amount to be cut.

I was not saying or implying that it is available by means other than 
the K3 knob, but it could easily be done by the software application if 
the author is willing to "do the math".  You might try asking.
